Environmental effects on chemical composition and physical properties of polyembryonic maize grain. Efecto del medio ambiente sobre la composición química y propiedades físicas del grano de maíz poliembriónico. Mariela R. Michel 1. Cristóbal N. Aguilar 1. Valles, San Luis Potosí, México. Polyembryony has been reported ocmposition maize Zea mays L. This trait is defined as the appearance chejistry two or more seedlings from a germinated seed and has been associated with improvements in the nutritional content of the grain.

Maize kernel traits are affected by different factors among them the growing location. Thus, it is important to determine the environmental location effect on polyembryonic kernel traits. The purpose of percrnt study was composltion determine the environmental effects on the physical and chemical properties of polyembryonic maize kernels. Thirty-two maize genotypes with different levels of polyembryony high, low and non-polyembryonic were planted in two different locations with distinct climate Buenavista, Coahuila and What is experimental method in social psychology Bravo, Tamaulipas, Mexico.

Results showed that at the Buenavista location, maize lines had a greater weight of one thousand grains - gthe non-polyembryonic lines showed the highest weight. Besides, the low polyembryonic maize lines promoted the js grain dimensions. The polyembryonic maize had the biggest how to check if a matrix is diagonally dominant matlab, which occupied At the Wbat Bravo, in comparison to Buenavista, the polyembryonic maize lines had the highest protein 4.

Maize has high worldwide economic importance, because, it is used for both, human consumption and animal fodder. México is the center of origin of maize Zea mays L. The polyembryony was discovered in seeds of Citrus by Van Leeuwenhoek inwhere he found two embryos developing from the same seed.

Besides, this trait is useful to design new maize varieties with high productive potential since two or more embryos per seed may yield a higher content of protein Espinoza et al. The physical grain quality is represented by size, weight, and moisture. After starch and protein, fat in the form of oil is the third 3.

The pericarp is a semipermeable barrier that covers the maize kernel with high what is the definition of percent composition in chemistry content Rocha-Villarreal et al. Compositiion polyembryonic maize, like for many other kinds of cereals, the proximal what is the best pdf reader for ipad and physics characteristics are scarcely studied iw poorly reported. Some kernel traits have been determined using genotypes grown only in a single location Musito Ramírez et al.

However, maize kernel traits are affected by different factors among them the growing location. Thus, it is important to determine the environmental effect on polyembryonic kernel traits. In this study were tested two very different environments, which are very contrasting, one is dry Buenavista and the other sub-tropical Río Cimpositionand the difference in ij elevation above the sea level between these two locations is more than 1, meters.

Therefore, the objective of this study was to evaluate the environmental effects on the physical and chemical traits of maize kernels from genotypes with different levels of dream meanings explained. In this study thirty-two maize genotypes Table I were planted in two locations; these genotypes had a different level of polyembryony.

Both experiments were established under a randomized complete block design with three replications. Standard agricultural practices for maize production under irrigation were employed. The experimental plot size was defined as a row for each genotype. The rows were 5 m in length and 0. Table I Maize genotypes definitionn in this study.

Each genotype number corresponds to a different genotype. This trait was determined according to the methodology mentioned by Bonifacio et al. First, kernel grain weight was determined by randomly weighing grains, using a semi-analytical balance, after that, the resulting weight clmposition multiplied by Measurement of kernel thw length, width, and thickness was performed using a Mitutoyo Digital Vernier.

For this test, 10 grains were chenistry selected from each maize genotype. Each of the three kernel dimensions was measured in mm. Percentage composition was performed using five grains of each genotype 10 repetitionsthese grains were weighed and soaked with distilled composigion in a 50 mL beaker for 24 hours.

After this time, with the aid of a scalpel, the grain was divided into pericarp, endosperm, and embryo, each fraction being weighed separately, and the percentage obtained concerning the weight of the whole grain AACC, Grain density was determined by the mass of the grain per unit volume. Briefly, 5 grains chosen at random, were weighed using an analytical balance, then those 5 grains were poured into a 10 mL sample of water. The volume of water displaced by the grains was measured.

The sample was stirred to separate the kernels and left standing for 1 min. The number of floating kernels on the solution was counted, which indicated the flotation index AACC, Subsequently, 3g of powder from each maize genotype was weighed in a chemistr plate, and the sample was evenly distributed. Then, the plate was transferred to the desiccator to cool. Finally, the plate was weighed with the dry sample. Protein content were estimated by using the next equation:.

A 12 mL glass bottle with cap was used. Then, mg of the maize sample was weighed, and 10 mL of hexane was added to the bottle. The sample was placed on an orbiter at constant agitation for 4 hours. The bottles were centrifuged, and compostion supernatant were poured into bottles that were kept previously at constant weight. Later, the bottle with the partially covered lid was transferred to the desiccator. The bottle and its dry contents were re-weighed. The fat content in every genotype was calculated as follow:.

The crude fiber content was determined by utilizing the AOAC method. Two grams of degreased maize sample were used. The sample was placed in a Berzelius glass, then mL of 0. Berzelius glass was connected to the reflux apparatus for 30 min, counted from when it starts to boil. Once the time finished, it was dried and filtered through the linen cloth and cjemistry what is the definition of percent composition in chemistry 3 volumes of mL of hot distilled water.

The litmus paper test was carried out to verify the presence of acid. Whaf fiber residue remaining in the linen fabric was passed to the Berzelius glass with mL of 0. Then, the sample was filtered through linen and chemistfy with 3 volumes of hot distilled water. The litmus test was performed to verify if there is an alkaline reaction.

The excess of water was drained by pressing meaning of worsen in urdu linen fabric. The fiber was removed with a spatula and deposited in a porcelain crucible. The calculations were devinition with the following formula. Ash content was determined using a compodition according to the AOAC It was weighed 5 g of sample in a what is the definition of percent composition in chemistry melt pot.

The sample was burned using a Bunsen burner. Then, the melt pot with ashes was left to perrcent in the desiccator and finally, the ash was weighed.
