등숙 시기 및 이삭 내 위치에 따른 찰옥수수 과피 두께 및 립중의 변화 = Change of Pericarp Thickness and Kernel Weight at Grain Filling Period and Kernel Set Position in Waxy Corn Hybrids (Zea mays L.)

다국어 초록 (Multilingual Abstract)

Pericarp thickness is thought to influence the palatability of waxy corn hybrids. In order to determine pericarp thickness and kernel weight, the present investigation was carried out at different grain filling stage and kernel set position in two waxy corn hybrids. The results showed that pericarp thickness did not have a substantial change as kernel weight increased until around 35 days after pollination and stayed constant thereafter. The correlation analysis indicated there is no relationship between the two traits at different grain filling stages. When kernel set position was considered, the average pericarp thickness and kernel weight had a tendency to decline from the bottom toward the ear tip. The standard deviation of the two traits at different kernel set position also tended to decline toward the ear tip but fluctuated at the bottom and ear tip. The correlation between the pericarp thickness and kernel weight at different kernel set position was significant in two waxy corn hybrids. This study suggests that pericarp thickness of fresh waxy corn ears harvested at around 24 days after pollination can be determined at any time after 18 days after pollination. We recommend collecting kernel samples for pericarp thickness from the middle part of an ear.
