摘要

甘蓝（Brassica oleracea，var.Acephala）含有对健康非常有用的完整营养成分。羽衣甘蓝的栽培需要充足的水。然而，气候变化导致土壤供水不稳定，降低了植物生产力。研究了土壤含水量对羽衣甘蓝形态和生理的影响，并确定了羽衣甘蓝栽培的最佳土壤含水量水平（100、80、60、40或20%）。土壤含水量影响羽衣甘蓝的生长、鲜重、生物量和水分利用效率，但不影响蒸腾速率和叶片相对含水量。羽衣甘蓝的最佳土壤含水量是60%的田间容量或21.50%的粉壤土实际含水量，生物量为12.35 g，水分利用率106.38%。

Morphology and physiology of kale plants under excess and deficient water conditions

ABSTRACT Kale (Brassica oleracea, var. Acephala) contains complete nutrients that are very useful for health. The cultivation of kale plant requires adequate water. However, climate change results in erratic soil water supply and decreases plant productivity. This study investigated the effect of soil water content on morphology and physiology of kale and to determine optimum soil water content level for kale cultivation (100, 80, 60, 40 or 20%). Soil water content affected growth, fresh weight, kale plant biomass, and water use efficiency, but did not affect transpiration rate and leaf relative water content. Optimum soil water content for kale was 60% field capacity or 21.50% actual water content on a dusty loam soil, with a biomass of 12.35 g and water use efficiency of 106.38%.
