不同地点的黄秋葵部分数量性状表达差异

The Expression Difference of Some Quantitative Characteristics of Okra(Abelmoschus esculentus) in Different Regions

以16个黄秋葵品种为材料,通过种植试验探究不同生态区的环境条件差异对黄秋葵品种数量性状的影响。结果表明:叶片长度、宽度在品种及地区间数据波动较大,因此这2个性状受品种及环境的互作效应较大;叶柄长在品种间差异较小,但受环境影响较大;果实厚度和果实长度在品种内容易出现不稳定的情况,而果实长度和果实直径在品种间的平均变异系数相对较小,分别为9.68%和8.68%,因此环境作用对其影响相对较小;单荚种子数在不同生态区表现出显著差异,易受环境影响;在品种类型中,矮杆类型、长果类型、红果类型的黄秋葵相较于其他类型更易受到环境的影响。

In order to investigate the effects of environmental conditions on the quantitative traits in okra, 16 okra varieties were used as the materials in different sowing sites. The results showed that the leaf length and leaf width fluctuated greatly among varieties and sites. Therefore, the two traits were more affected by the variety and environment. The petiole length was less varied among varieties, but it was greatly affected by the environment. Fruit thickness and fruit length were prone to instability among the varieties, 9.68% and 8.68% respectively, while the average coefficient variation(CV) of fruit length and fruit diameter among varieties was less significant. The number of seeds per pod had significant differences in different sowing sites, so it was susceptible to environment. Dwarf type, long fruit type, and red fruit type of okra were more susceptible to the environment than other types.
