日光温室中不同架式对葡萄光合特性及果实品质的影响
Effects of Different Training Systems on Photosynthesis and Berry Quality of Grapes in Solar Greenhouses
摘要
Abstract
Objective]This experiment aims to use "Summer black"grape in solar greenhouse to study the effects of different training systems on photosynthesis and berry quality,in order to evaluate the perform-ance of pergola and vertical trellis systems of grapes in solar greenhouses.[Method]The photosynthetic pa-rameters such as Net photosynthetic rate (Pn),Transpiration rate (Tr),Stomatal conductance (Gs)and In-tercellular CO2 concentration (Ci)were determined by Li-6400 portable photosynthesis system.The indexes of berry quality were measured in the maturity stage,and Vitamin C content was determined by 2,6-Dichlo-rophenolindophenol titration method,and the total acid content was measured by NaOH titration method.[Re-sult]The Pn value and the chlorophyll content in pergola training system in each growth period were higher than those in vertical trellis system.From fruit enlargement period,color rotation period to maturity stage,the peak and mean of Pn in two training systems were gradually reduced.Pn showed significant correlation with other photosynthetic factors.Single grain weight and soluble solids in pergola training system were significantly higher than those in vertical trellis system.Single panicle weight,total sugar and vitamin C content were high-er than those in vertical trellis system,but the difference was not so significant.[Conclusion]Summer Black grapes by pergola training system showed better performance in photosynthesis and berry quality than those by vertical trellis system in solar greenhouses.关键词
