谷物种子大小对于植株早期发育、幼苗长势以及谷粒产量的影响,许多研究者早有阐述,但种子重量对芽鞘长度的影响,仍很不清楚。而芽鞘长度及其与植株高度的关系,对育种有重大意义。由于对矮秆育种目标的研究往往导致芽鞘长度缩短,以致幼苗长势与出苗率降低。因此,对芽鞘长度的变异性及其与茎秆长度的相关性,包括种子重量对芽鞘大小影响
The effect of grain size on plant early development, seedling growth and grain yield has been well documented by many researchers, but the effect of seed weight on the length of the sheath is still unclear. However, the relationship between the sheath sheath length and plant height is of great significance to breeding. Studies on dwarfing breeding objectives often led to shortened shoot sheath lengths, resulting in reduced seedling emergence and emergence rates. Therefore, the variability of the length of the Ophiopogon japonicus and its correlation with the length of the stalk, including the influence of the seed weight on the Ophiopogon japonicus
