“…The limits between the two populations were described as the minimum of the curves that occurred at~2.7 μm. The granule sizes were classified into large (>15 μm), medium (5-15 μm), and small (<5 μm) granules (Ketthaisong et al 2013). Average diameter of large, medium, and small granules ranged between 16.6 to 26.2, 5.7 to 14.2 and 0.4 to 4.9 μm, respectively.…”

The characteristics on physicochemical and morphological properties of starches were investigated in fresh waxy corn kernels. Starches were isolated from eight waxy corn genotypes at the immature kernel stage growing in Thailand. The starch content showed variation with genotypes and ranged from 77.76 to 90.97 %. Granule size distribution showed a two population of starch granules with peak values ranged from 0.8 to 1.1 μm (small) and 9.0 to 12.2 μm (large). Genotypes were also significantly different for average chain length (CL), unit chain length distribution and pasting properties. The small granule (<5 μm) was negatively correlated with CL and degree of polymerization (DP) 25-36 of amylopectin (−0.82 and −0.67, respectively, P<0.01). And a strong relationship between trough and final viscosity was consistent with the contribution of pasting properties.

Starches isolated from five corn cultivars namely C4, C5, C6, C8, and C15 were investigated for their physicochemical and structural properties. The amylose content of corn starches varied from 24.74 to 30.32 g/100 g among the cultivars. The starch granules showed polyhedral granule shapes and differences in their mean granule size ranged from 2.3 to 19.5 μm. The starch samples showed A-type diffraction pattern with strong reflection at 15.25, 18.11 and 23.33°.Pasting profile, textural and thermal properties of corn starch showed the cultivar differences.Raman spectroscopy showed the major band intensities at 1340, 1082, 940, 865, 523, 485, 440 and 412 cm -1 . Syneresis and turbidity of gelatinized pastes of starches varied among the cultivars and increased progressively with the increase in storage period. The present study can be used for identifying differences between corn genotypes for starch quality and could provide guidance to possible industries for their end use.

“…The following formula is used to calculate the speed of germination (SG): Dry weighs of seed parts were determined for all seed parts. Three replications of 10 seeds for each treatment were soaked in water containing 0.16% sodium hydrogen sulfite at 50 • C for 24 h [15]. Whole seed was separated into embryo, endosperm, and pericarp and then dried at 70 • C for 48 h. The weights of dry seed parts were expressed as mg/seed and total seed percentage.…”

The use of combinations of two or more genes controlling carbohydrate characters of corn is an attractive way to improve table quality of sweet corn. Poor seed quality of the inbred lines hinders the progress of this strategy for hybrid seed production. The objective of this study was to evaluate sweet corn inbred lines with combinations of double and triple recessive genes for germination percentage, seed vigor, total sugar content, and starch content. Eleven sweet corn genotypes including seven inbred lines (F6 generation) with different combinations of genes controlling carbohydrate characters and four F1 hybrids were used. The germination experiment was conducted under standard test between papers (BP) and accelerated aging (AA) test. The data were recorded for germination percentage, germination speed, normal and abnormal seedling, seedling length, and seedling dry weight. The seeds were analyzed for total sugar and starch content in endosperm at maturity stage. The results showed that single recessive genotype (sh2sh2) had high germination percentage and seedling vigor. The combinations of bt or sh2 gene with wx gene resulted in low germination percentage and poor seedling vigor. However, combinations of triple recessive genes (btbt sh2sh2 wxwx) had good germination in BP test but they performed poorly in AA test.
