无棱丝瓜砧木对苦瓜品质和光合生理的影响
Effects of wild luffa rootstocks on fruit quality and photosynthetic physiology of bitter gourd
摘要
Abstract
[Objective]In order to provide scientific support to rootstock selection of bitter gourd,the effects of wild luffa rootstocks (Luffa cylindrical Roem.) on fruit quality and plant photosynthetic physiology were studied.[Method]Bitter gourd cv."Guinongke 2" were grafted on four different luffa rootstocks (IL1:Luffa acutangula cv.Shuangyi; IL6,IL9,IL16:Luffa cylindrica) to study effect of rootstocks on fruit quality,leaf chlorophyll content and photosynthesis characteristics of bitter gourd.[Result]All rootstocks improved fruit quality,and the best effect came from rootstock ILl6.The chlorophyll contents of young leaves of grafted seedling were significantly improved by all rootstocks,however,remarkably decreased in mature leaves.The most significant impact of chlorophyll content came from rootstock IL9.All rootstocks significantly improved the photosynthetic rate of grafted seedling with the highest one from rootstock IL9,while grafted seedlings with rootstock IL16 had the highest apparent quantum efficiency.Light saturation point and light compensation point were significantly decreased by grafting.[Conclusion]Luffa rootstocks IL9 and IL16 could better improve the fruit quality and luminous energy utilization of bitter gourd than other rootstocks.关键词
