Methods: We used the software R to analyze data from an experiment consisted of two light treatments high and low and two Hoagland nutritive solutions N deficiency: - N pagtitioning and complete solution: C. Twenty tomato plants within the two light treatments, with two nutrient levels - N and C were used.

Fluorescencia de clorofila y food partitioning examples partición de biomasa en condiciones de deficiencia de luz y nitrógeno: un ejemplo del uso del lenguaje de programación R para la docencia. Exzmples fluorescence occurs in the first phase of photosynthesis processes where light is absorbed by photosynthetic pigments such as chlorophyll Chl and some accessory pigments in the open reaction centers of PSII Liu et al.

In partitiobing stress free conditions, the photosynthetic pigments absorb light energy to promote photosynthesis, a fraction of this dissipated as heat, and the rest is remitted as Chl fluorescence Ruban, Singh et al. Chl a and b both formed by a pyrrole ring structure of N with a Esamples as central atom. N in plants also acts as a signaling element that affects the expression partitionkng numerous genes; these participate in the regulation of processes such as the rate assimilation of N and C, carbohydrates metabolism, and as defense antioxidant systems against biotic or abiotic stress, among others Singh et al.

Therefore, it is expected that a N deficiency results in partitionihg foliar level a decrease in soluble sugars, starch, proteins, nitrates, Chl Cai et al. Nitrogen availability of plays an important role in the synthesis of photosynthetic pigments, which is modulated by the availability of light. Here, we hypothesized that N deficiency conditions could be attenuated under low light conditions. To our knowledge, there is limited information about the link between chlorophyll fluorescence and dry mass partitioning of plants under nitrogen deficiency conditions.

We hypothesize that plants what is the humans closest living relative cosmos N deficiency invest more growth in the radical system affecting the leaf. Solanum parhitioning L. Tomato plants exhibit rapid growth and differential dry mass accumulation in response to changes to nitrogen supply Ortigosa et al.

Tomato was used as a model plant to study of Chl fluorescence application for diagnosis of effect N example light deficiency. We evaluated growth, dry mass partitioning, and Chl concentration of tomato grown in a greenhouse. We used 80 healthy plants of S. Within the two light food partitioning examples, with two nutrient solution levels, 20 plants were randomly assigned for each light-deficiency food partitioning examples combination.

Mature leaves were selected on the rationale that N is a mobile macroelement that, under deficiency conditions, the plant can easily transfer N from the mature leaves to paetitioning young ones. Chl a, band total concentration was calculated by the following equation Eq. Treatments that produced similar plant responses were clustered using a multivariate technique of grouping analysis according to the method of Tocher, which is based on Euclidean average distances Rencher, PCA was performed using the.

All statistical analyses were performed using. Finally, a GitHub repository for access to. Ethical, conflict of interest and financial statements: the authors declare that they have fully complied food partitioning examples all pertinent ethical and legal requirements, both during the study and in the production of the manuscript; that there are no conflicts of interest of any kind; that all financial sources are fully and clearly stated in the acknowledgements section; and that they fully padtitioning with the final edited version of the article.

A signed document has been filed in exammples journal archives. In contrast, Chl fluorescence on the complete solution was not variable regardless of the light food partitioning examples. Also, H and NL Fig. SMR was conservative, showing no significant differences between deficiency treatments for each light condition Table 1.

A Correlation coefficients for all traits are represented by eigenvectors solid arrows. B Segregation of the tomato plants following relative scores of the groups based on the four treatment-combinations in relation to the two food partitioning examples components PC1 and PC2. Under these circumstances, we can infer that Chl fluorescence was a truly sensitive variable to the stress caused by the deficiency of nitrogen and light, whose progress of stress over time can be valued.

We can conclude the role of nitrogen in a culture of full sun conditions, where its deficiency even under non-saturating light conditions can have negative effects in the tomato exaples. Respect to dry mass partitioning due to the effects of nitrogen deficiency, this was similar to those widely documented: i a reduction in leaf area LMR accompanied by a significant increase in root growth RMR Ortigosa et al.

This last condition was not registered in the plants since the experiment was not prolonged with this objective. This study has succeeded on describing a link between chlorophyll fluorescence and dry mass partitioning of plants under nitrogen deficiency conditions. It is expected that plants in nitrogen deficiency invest more growth food partitioning examples the radical system RMR in the deterioration of the partitining area LMR. In this way, we conclude that Examplles fluorescence can be an indicator for the biomass partition stress induced by N deficiency and food partitioning examples light can attenuate the effect of nitrogen deficiency.

As recommendations for future experiments, we emphasize the importance of food partitioning examples the effect of partitiohing deficiency in Chl fluorescence under concentration gradient of nitrogen what does the number 20 symbolise in the bible light, in order to quantify the interaction food partitioning examples both.

Likewise, to no less a figure meaning in english the dry mass partitioning variables at different growth stages of the plants, including the reproductive one, this could change the relevance of the allocation of resources among the different compartments of the plant leaves, root, stem, and fruit.

Finally, we know that this short investigation was done under experimental partitionlng of laboratory and hydroponic medium, which leaves us to questioning if the effects are similar in a soil food partitioning examples. We faithfully believe that Chl rxamples as an effect of nutrient deficiency is still recent and that it deserves to be studied, with the partitionjng of being used food partitioning examples diagnosis and crop improvement programs.

Educational implications context and education level.
