葡大灵和利果美配施对‘红地球’葡萄生理生化特性和品质的影响

摘要

The effects of treatments of growth regulators PuDaling and Legumier (600 times)at differ-ent concentrations were studied on the physiological,biochemical characteristics of leaves and fruit quality of 6-years-old‘Red Globe’plants.The results showed that with the increasing of the concentrations of Pu-Daling,the activity of SOD and POD increased firstly and then reduced,MDA content reduced firstly and then enhanced.The maximum activity of SOD and POD in the leaves was found in the combined treatments with PuDaling at 200 times and Legumier at 600 times,were higher by 35.03% and 45.28% than CK, MDA content was lower by 32.18% than CK.The combinated treatments with PuDaling at 200 times and Legumier at 600 times had the maximum length,diameter,spike weight,grain weight,soluble solid content of fruit,which increased by 14.84%,10.1 9%,34.91%,1 6.54% and 20.25% than CK.The treatments also had the lowest acid content,reducing by 23.44% than CK.%试验以6年生露地栽培的‘红地球’葡萄植株为试材,研究不同浓度的葡大灵和利果美(600倍液)配施对‘红地球’葡萄膨大期生理生化特性和成熟期果实品质的影响.结果表明：随着葡大灵浓度的增加,葡萄叶片的SOD、POD活性均呈现先升高后降低的变化趋势,MDA含量先降低后升高,其中200倍液葡大灵和600倍液利果美处理的‘红地球’葡萄SOD、POD活性最高,分别高出CK 35.03%和45.28%,MDA含量最低,较CK低32.18%.果实品质方面,200倍液葡大灵和600倍液利果美处理果实的纵径、横径、穗质量、单果质量和可溶性固形物含量最高,分别较CK高出14.84%、10.19%、34.91%、16.54%和20.25%,可滴定酸含量最低,低于CK 23.44%.
