Study On The Effects Of Rootstocks On Growth And Physiological Biochemistry Of Grape

This experiment for verifies the effects of rootstocks ongrowth and physiological biochemistry of grape, Taking the 13 grapesstocks variety (table 1), 3 cultivateds variety and plants grafted oninner-rootstocks of grape provided by the teaching base of college ofhorticulture and gardening of Hunan agricultural university and NongkangHorticulture Development limited company for materaials. Study on thebiology characteristic of grape rootstocks, the cutting characteristic, theinfluence of physiological biochemistry and plants grafted oninner-rootstocks and so on, the findings as follows:1. In the biology characteristic observation of rootstocks variety, thesurvival rate of Beta, SO4, 5BB, 3309C, 8B, No 8 of Huajia is higher, It'sas follwed: 65%, 44%, 40%, 37%, 33% and 31%. Beta takes root to leadand the Survival rate respectively is 65% and 62%, the cutting ability isstronger than other rootstocks variety. Rooting rate of SO4 and 5BB is40% and 48%, but Survival rate is 44% and 40%, both of cutting ability ismedium.2. In the experiment of three cultivateds variety GaoQi, Victoria andthe red Earth grafted on 5BB and SO4, the effect is good. Also the stock toscion aspect and growth, bearing, fruit quality, physiological biochemistrycompoud and inorganic nutrition element has remarkable influence.The growth, germinating rate and the bearing rate of Plant grafted on 5BB ishigher. Absorbancy of Leaf blade to inorganic nutrition element is strong,fruit quality is good, degree of hardness big, stored, the ABA content ofpost harvest is lowly, and thus causes the variety prematurely dropped fruitto be few. The growth ability of plant grafted on SO4 is medium,germinating rate and beating rate is higher, fruit hardness is highest, thusfruit stored, fruit quality and flavor is good.3. In the effect of plant grafted on rootstocks with 5BB and SO4 andgrafted on inter-rootstocks with Victoria, again grafts on the marvelousnon-nuclear variety, can remarkably sharpen its germinating ability. Solvesthe germinating difficulty of plants grafted on rootstocks.The above findings for the development grape industry havereasonably provided the basis using the stock.
