“…Starch content differed across the locations since quality of grain depend on interplay between the genetic characteristics of the plant and external factors that influence plant growth such as climate, soil and management practices. In this study, the different starch content among sites contradicted the findings by Buresova et al (2010) who indicated that starch content was significantly affected by cultivar and year. They indicated that starch content was not significantly influenced by growing variant or site.…”

“…They indicated that starch content was not significantly influenced by growing variant or site. The starch content of maize grains in this study differed across the seasons and this corroborates the findings the findings by Buresova et al (2010) who reported that starch content was significantly affected by weather during growing season. They indicated that warm weather during the growing season had a significant positive effect on starch content.…”

Maize seed quality during storage can decline to a level that may make the seed unacceptable for planting purpose. A factorial experiment randomized in complete block design with three replications was conducted during 2011/12 and 2012/13 planting seasons. The experiment comprised of three cropping systems (cowpea-maize rotation, monocropping maize and intercropped maize), three sites (Potchefstroom, Taung and Rustenburg) and two rates of nitrogen fertilizers applied in kg ha -1 at each site (0 and 95 at Potchefstroom, 0 and 92 at Rustenburg, 0 and 113.5 at Taung). The experiment was conducted to investigate the effect of cropping system, site and nitrogen fertilization on maize seed quality. Maize seeds harvested from Potchefstroom and Rustenburg had significantly (P < 0.05) higher oil content of 4.4% than maize seeds harvested from Taung. Maize plots applied with nitrogen fertilizer had significantly (P < 0.05) higher seeds protein content of 8.7% than maize plots without nitrogen fertilizer application. Maize seeds harvested from Potchefstroom had significantly (P < 0.05) higher starch content of 71.8% than maize seeds harvested from Rustenburg and Taung. Cowpea-maize rotation and intercropped maize had significantly (P < 0.05) higher seed phosphorus content of 0.50 and 0.52%, respectively than monocropped maize. In this study, site as factor played a vital role on quality of maize seeds. Maize seed quality was improved significantly by the interaction effect of site x season.

“…In general, triticales contain around 62.4-70.9% of starch with approximately 20.8-26.4% of amylose content (Burešová, Sedláčková, Faměra, & Lipavský, 2010). According to previous reports, substituted triticales contain lower amounts of amylose than complete triticales (Navarro-Contreras et al, 2014), which have been related to the size of starch granules (Ao & Jane, 2007).…”

The starch granules of complete and substituted triticale genotypes were analyzed for morphology and size distribution using scanning electron microscopy (SEM) and laser diffraction, respectively. A quantitative comparison of total carbohydrate, starch, and amylose contents was also performed. The results showed that the complete triticales contained 8.8% more total carbohydrate content and 13.8% more starch content than the substituted ones. No significant differences in the average amylose content (22.8%) were observed between the two sets of triticales. However, the A-and B-type starch granules of the substituted triticales showed significant differences in amylose content. Starch granule distribution profiles showed that the sizes of the A-and B-type starch granules of complete triticales were larger (in the range of 18-41 μm and 2-13 μm, respectively) than those of substituted triticales (in the range of 8-38 μm and 0.5-6 μm, respectively). This study demonstrated that the starch in triticale genotypes differs in physicochemical properties.Keywords: triticale; SEM; laser diffraction; starch; amylose; carbohydrate Se analizaron los gránulos de almidón de genotipos de triticales completos y sustituidos en morfología y distribución de tamaño utilizando microscopía electrónica de barrido (SEM, por sus siglas en inglés) y difracción láser, respectivamente. Se realizó una comparación cuantitativa del contenido de carbohidratos totales, almidón y amilosa. Los resultados mostraron que los triticales completos contienen 8,8% más en contenido de carbohidratos totales y 13,8% más de contenido de almidón que los triticales sustituidos. No se observaron diferencias significativas en el contenido de amilosa (promedio 22,8%), sin embargo, los gránulos de almidón tipo-A y tipo-B de los triticales sustituidos mostraron diferencias significativas en el contenido de amilosa, pero no los respectivos gránulos de los triticales completos. El análisis del perfil de distribución de los gránulos de almidón mostró que los gránulos de almidón tipo-A y tipo-B de los triticales completos son de mayor tamaño (rango de 18-41 μm y 2-13 μm, respectivamente) que el de los triticales sustituidos (rango de 8-38 μm y 0,5-6 μm, respectivamente). Se concluye que el almidón de los genotipos de triticales difieren en las propiedades fisicoquímicas estudiadas.

“…16 Triticale grain dry matter contains 62.4%-70.9% starch, a content that is dependent upon cultivar and year. 17 A recent scanning electron microscopy study of triticale starch granules during endosperm and seed development indicated unique and inherent structures, such as channels or pores that may facilitate the flow of hydrolytic enzymes into the granule matrix. 18 In addition, triticale starch has the apparent advantages of low phenolic acids content that otherwise negatively impacts starch hydrolysis, and a lower gelatinization temperature (of 65-68°C) compared to those of barley, wheat, and corn (in the range of 72-75°C; personal communication, T. Vasanthan, University of Alberta).…”
