| 摘 要： | 采用人工遮光的方式,研究了挑旗-开花期弱光对强筋小麦植株生长发育的影响。结果表明,花前遮光抑制了强筋小麦地上部各部位的干物质积累,提高了退化小花和不孕小穗数的比例,与对照相比,表现为小麦株高变矮、干重降低和穗粒数减少。遮光撤除后,强筋小麦植株各部位干重出现补偿性增长。花前遮光后,强筋小麦穗数和穗粒数降低,千粒重提高,产量显著下降。花前遮光对强筋小麦干物质积累的影响存在明显的基因型差异。

| Abstract: | In order to study the effects of low light on the growth and development of wheat,two strong-gluten wheat cultivars,GC8901 and JN17 were first selected.After that,a self-made tent was used to shade wheat plants from flag leaf stage to anthesis under field conditions,and unshaded plants were used as control group.The results indicated that pre-anthesis shading inhibited the dry matter accumulation of each component part in wheat,increased the ratios of degraded floret and sterile spikelet.This dwarfed plant ... |
