Chemical composition, secondary and primary metabolites of Tithonia diversifolia related to climate. Composición química, metabolitos secundarios y primarios de Tithonia diversifolia relacionados con el clima. Cuban Journal of Agricultural Sciencevol. Abstract: To establish the relationship between chemical composition, secondary metabolites, primary metabolites and digestibility chemistey organic matter, dry matter, protein, NDF and ADF of Tithonia diversifolia and climatic if, the correlation study was carried out.

The indicators were: What is composition of matter in chemistry chemical composition: ADF, NDF, lignin, cellulose, hemicellulose, cellular content, OM, ash, N, Si, Ca, P and Mg; B secondary metabolites: total tannins, total phenols, total condensed tannins, fiber-bound condensed tannins, free condensed tannins, alkaloids, saponins, triterpenes, steroids and flavonoids, and C primary metabolites: glucose, fructose, sucrose, N, verbascose, stachyose and raffinose.

For secondary metabolites, total condensed tannins and free condensed tannins stood out with temperatures and indicators of rain values of r between 0. In vitro digestibility of DM correlated r between Similar performance was registered for digestibility of organic matter and the r varied between Compositino showed the specific and variable effect of climate compowition in the studied indicators, which is useful for the efficient management of this plant under climate change conditions.

It what is composition of matter in chemistry recommended to consider these results to counteract the negative effect that secondary metabolites of Tithonia diversifolia can cause in ruminant feeding systems, apply mathematical modeling co,position predict the performance of these substances with climatic factors and other aspects of this plant management, as well as extend this type of research to other plants of interest to livestock.

Keywords: antinutritional factors, chemical composition, digestibility, temperature, rain.

Since the 90s of last century, it has been argued that cattle rearing in tropical countries has to be profitable and competitive, based on the minimum use of imported inputs, friendly to environment and use of local resources Roggero et al.

This geographical area has the greatest plant biodiversity, but animal feeding systems are mainly based on the use of few plant species. The use of shrubs in livestock systems has gained great importance in recent years due to its nutritional, productive and environmental contribution Schultze-Kraft et al. Gray stood whatt due to its genetic diversity Del Val mattdr al. In addition to the previously mentioned benefits, this plant contains secondary metabolites Verdecia that, due to its chemical characteristics, wjat it added value since its extracts can be used as insecticide and herbicide, among other properties Miranda et al.

Plants pastures, forages and shrubs, chemistyr what is composition of matter in chemistry used as food, in tropical areas, show marked seasonal yield, which responds to the existence of two well-defined climatic seasons rainy and dry periods. Tithonia does not escape this effect and its lower yield has been evidenced in dry season Ruiz et al. Considering the above, the objective of this study was to determine the relationship between chemical composition and secondary metabolites of Tithonia diversifolia with some climatic factors.

Data obtained by Verdecia was used. This data came from an experiment with Tithonia diversifolia of two years of established in plots of 0. It showed 6. Mean temperature and annual rainfall of cmoposition experimental period were No irrigation or fertilization was used. Samples were taken from 10 random plants per replicate samples in totalcut at 15 cm above soil level and were composed of leaves, petioles and stems smaller than 2. An amount of samples were analyzed in the two experimental years.

In addition, maximum, minimum and mean temperatures were quantified, as well as total rain and number of days with rain between samplings. Correlation coefficients Visauta were established what is composition of matter in chemistry secondary metabolites total phenols, total tannins, fiber-bound condensed tannins, free condensed tannins, alkaloids, saponins, triterpenes, flavonoids and steroidsas well as chemical composition NDF, Ib, lignin, cellulose, hemicellulose, cellular content, organic matter, ash, nitrogen, Si, Ca, P and Mg ; digestibilities of OM, DM, CP, ADF, NDF, what does dating a unicorn mean sugars verbascose, whaf, raffinose, glucose, fructose and sucrose of Tithonia diversifolia with some climatic factors maximum, compoistion and mean temperatures, number of days with rain and total rain.

The correlation between climate factors and chemical composition was variable table 1. The highest coefficients r were obtained for P, with the maximum temperature 0. For the rest of the chemical composition indicators, correlations were low or not significant. The highest correlations table 2 were found: between total phenols, total condensed tannins, fiber-bound condensed tannins and free condensed tannins with maximum temperature between 0.

For the rest of the secondary metabolites, correlations were low introduction to food science and technology pdf download not significant. The highest coefficients between verbascose and stachyose 0. For the rest of sugars, no relationship was found with temperatures, while relationships were low or not significant with rains and their distribution table 3.

DM in vitro digestibility DMIVD and of organic matter OMD were negatively correlated with temperatures, rains and their distribution, while in true digestibility DVcorrelations were significant only with temperatures. The highest correlations between digestibilities of protein CPDacid detergent fiber ADFD and neutral detergent fiber NDFD were obtained with rains and their distribution, although the latter also correlated with minimum temperature table 4. Most of research on yield and quality of whar, forages and other crops of interest for livestock compoxition carried out in field experiments and differences in the results have been explained by regrowth age, frequency what is composition of matter in chemistry cutting height, fertilization, irrigation, management, ie and varieties, among other factors.

While the aspects of the climate have been treated in a general way through the performance of its indicators in chemiztry periods. It is established science that climate features temperatures, rainfall, humidity and some others act in an interrelated manner on yield and quality of pastures. However, in the current research, the hypothesis of studying the individual influence of some climate factors temperatures, rainfall and their distribution on chemical composition, secondary metabolites and digestibility of Tithonia diversifoliawas used.

For this, climate data corresponding to each growth period were used in which samplings and chemical analyzes of studied indicators, during two years, what is the theory of evolution quizlet carried out. In this way, enough data was obtained to establish accurate correlations.

Furthermore, it was considered significant when the correlation coefficient reached a value superior to 0. References indicate the benefits of the chemical composition of I, characterized by high protein values, moderate contents of fiber elements and acceptable mineral content, which whhat depending on agronomic management variety, frequency and mahter height, fertilization, regrowth age hcemistry some other aspects to which the plant is subjected.

However, information shows high variability of values of chemical composition indicators with management Verdecia et al. Correlation coefficients between indicators of chemical what is composition of matter in chemistry and climate factors were, in general, low and with high variability, except cellulose, OM and P table 1. Negative correlation found between cellulose and maximum temperature could be possibly related to the fact that maximum temperatures were higher than optimum temperature for complsition growth and had a negative influence on it.

However, correlations with rain and its distribution were negative and what is composition of matter in chemistry, indicating the possible alteration of the synthesis of this what is composition of matter in chemistry. This confirms the findings of Nava et al. Negative complsition highly significant correlations of N with rain and its distribution could be related to the dilution effect suffered by N, as well as the probable decrease in the absorption capacity, by the root, of this element due to the existence of a humidity gradient in the soil that does not favor the referred what is composition of matter in chemistry Taiz and Oof Variability in the mineral composition of Tithonia has been reported what is amazon ppc and how does it work on the management, including the climate, to which it is subjected Verdecia and Guatusmal-Gelpud In the case of minerals Si, Ca and Mgno adjustments were found or they were low with climate factors, which could indicate some independence from climate factors, aspects that need future research.

Nevertheless, the highest correlations only corresponded to P with the maximum and mean matte. The above could indicate that the absorption of this element is favored with the increase of maximum and mean temperatures. Rivera et al. In this way, saponins have antibacterial activity and intervene in the decrease o removal of protozoa from the rumen. Flavonoids have antimicrobial properties and terpenoids can reduce the peptidolytic activity of ruminal bacteria and effectively inhibit the growth chemkstry ruminal bacteria involved in ammonia production.

This variety of chemical compounds that flavonoids, alkaloids, saponins, triterpenes, and steroids are constituted by, could be responsible for the variable relationships o these secondary metabolites and climate factors, with a low correlation coefficient in the current chemkstry. For this chemisry, future experiments are needed to deepen in this response, as well as its effect on animals. In relation to tannins, these are high molecular weight polyphenolic compounds with different properties, there are several chsmistry and these compounds can inhibit enzymes cellulases and pectinasesproduce alterations in cell walls, reduction of CH4 emissions and affect the transport of carbohydrates and amino acids, among other functions Makkar et al.

The chemical determination of these compounds requires specific analytical procedure, generally expensive, which is why their qualitative determination is frequently used What is composition of matter in chemistry et al. However, like all qualitative analytical procedure, it depends on several factors chemjstry and part of the sampled domposition, concentration of the compound in the material and sensitivity of the reagent to be used so the result may be variable and not reflect the true composition of the sample.

In Tithonia diversifoliaGallego-Castro et chemustry. Scull et al. In the present research, the best correlations were obtained in total condensed what are the 5 major types of infectious agents and free condensed tannins with temperatures maximum, minimum and average and rains and their distribution, which evidences the positive effect of climate factors on concentration of casual relationship meaning in hindi chemical compounds of Tithonia.

Therefore, it would be of interest to know what would be the limit value of temperatures and rainfall that would promote appropriate values of these compounds that compowition not negatively influence how are ferns classified physiology and nutrition of animals that consume this plant.

In relation to sugars, information is limited and has been based on the qualitative determination of reducing sugars. In the current research, the best correlations were found in verbascose and stachyose with temperatures maximum, minimum and mean. These sugars are composed by galactose, glucose compositlon fructose molecules in proportions and for stachyose and verbascose, respectively.

However, there was no correlation between glucose and fructose with climate factors, which attracted attention, since these substances are the basis for what is composition of matter in chemistry synthesis of verbascose and stachyose, classified cuemistry oligosaccharide and matyer, respectively. In addition, these compounds, when consumed, can produce flatulence and have a negative effect on animal nutrition. Therefore, all these aspects require future what is composition of matter in chemistry.

Digestibility indicates the efficiency of use of an indicator DM, OM, CP, NDF and ADF, among others by the animal, and it ehat been reported that it depends on pasture management, as well as internal factors such as content of fiber compounds, lignin and silica, among other aspects Valenciaga et che,istry. On the other hand, La O et al.

As these compounds of the plant vary according to the climatic season, it is expected that digestibility will also fluctuate and, therefore, climate factors can be considered to indirectly influence on digestibility. In the references consulted, no article similar what is composition of matter in chemistry the present study was found chwmistry it was interesting to find the negative and significant influence between maximum, minimum and mean temperatures correlation coefficient between These elements could serve as an alert to carry out the efficient management of this species during rainy period, characterized by high temperatures and precipitations.

Furthermore, it is necessary to consider the cheistry for future studies to counteract the probable negative effect that secondary metabolites of Tithonia diversifolia may cause in ruminant feeding systems. It is also necessary to apply mathematical modeling to predict the performance of these substances with climate factors and include xhemistry indicators such as duration and intensity of light, as well as consider these results when designing the efficient management of this plant and extend this type of research to other plants of interest for livestock.
