摘要: 为了探究环境温湿度对黄秋葵结荚量的影响,以矮秆、中秆和高秆3个不同类型的6个栽培种为材料,开展大棚设施环境和海南大田环境栽培,监测环境温湿度,观测黄秋葵结荚量。结果表明:结荚盛期,设施大棚栽培环境下,随着温湿度的变化,LQK-1和HQK-3的小区周平均结荚量明显增加,整体比大田环境高;绿秋葵品种的单株周平均结荚量(35~65)总体比红秋葵品种的单株周平均结荚量(16~39)高,且达到显著差异,其中红秋葵HQK-2的单株周平均结荚量(2~2.7)最低。不同类型黄秋葵结荚量受环境温湿度影响不一致,矮秆型较适合大棚设施环境栽培;结荚量可作为DUS测试的选测性状来区分品种。

Abstract: In order to explore the effects of environmental temperature and humidity on pod quantity of Abelmoschus esculentus L., six varieties of okra (three different types) were applied as materials and greenhouse facility cultivation and the field cultivation (as control) were carried out in this study. Environmental temperature and humidity and pod quantity of okra were surveyed. The results showed that under greenhouse cultivation environment, along with the changes in temperature and humidity, the average pod quantity (each week/one plot) of variety LQK-1 and HQK-3 increased compared with that under field cultivation. Also, the average pod quantity (each week/one plant) of green okra varieties (35- 65) was more than that of red okra varieties (16-39) at a level of significant difference, and the average pod quantity (each week/one plant) of red variety HQK-2 (2-2.7) was the lowest. The effects of environmental temperature and humidity on pod quantity of different okra types were inconsistent. The dwarf type is suitable for greenhouse facility cultivation. The pod quantity can be used as a selection characteristic for DUS testing to distinguish varieties.
