新疆高产春大豆鼓粒的粒位差异研究
Study on Seed Position Difference of Seed-bulging of High-yield Spring Soybean in Xinjiang
摘要
Abstract
This study aims to find out the increasing law of seed weight of high-yield spring soybean in Xinjiang.In the field experiment,4 medium mature and high-yield spring soybeans(lines) including Jinyuan 20,11-109,Xindadou 27,and Heinong 61,were chosen as materials,and the regularity of the stem of different section with pods,the same node with different pods and 3 seed pods of seed-bulging process,and single seed weight variation were investigated were investigated in 2015 and 2016.The result showed that the pod seed-bulging stage of the main stem with basal section (1st-3th) of different varieties (lines) were the earliest and longest,and the single seed weight was the lightest.At the top section (1st-3th) of the main stem,the initial seed stage of pod was the last,the seed-bulging stage was the shortest,and the single seed weight was between the basal section (1st-3th) and the top section (4th-6th).At the top section (4th-6th) of the main stem,the initial seed and seed-bulging stage of pod was between the basal section (1st-3th) and the top section (1st-3th),and the single seed weight was the biggest.The initial seed and terminal seed stage of pod in the main stem increased with the differences of the node.The maximum differences were 9-24 days and 6-15 days respectively.The initial seed stage,seed-bugling stage,seed-bugling rate and single weight of large and medium pods with the same node were better than pods.Both the weight gain rate and single seed weight of 3 seed pods were middle seed (s) ＞ distal seed ＞ seed.The difference in the seed-bugling process and single seed weight were the same plant with different nodes ＞ the same node with different pods ＞ the same pod with different seeds.The effect of seed-bugling process on yield was affected by single seed weight.Differences in the seed position of seed-bulging and increased single plant with seed-bugling stage were advantageous to high-yield.The seed-bugling stage of single plant with yield of 5 000-5 600 kg·ha-1 was 45-60 days.关键词
