Applicability Evaluation Of Different Grape Rootstock-scion Combinations Under Protected Cultivation

The experimental materials were ‘Summer Black’ grape grafted on 11 kinds of rootstocks and ‘87-1’grape grafted on 9 kinds of rootstocks.Comparing the effect of different rootstocks have on the environment adaptation,perinatal regulation characteristic,new shoots laboring-saving characteristics,yield characteristics,quality characteristics of ‘Summer Black’ and ‘87-1’ to evaluate the suitability of the 20 rootstock-scion combinations for planting in the greenhouse.This paper provided a theoretical basis and reference basis for selecting the best rootstock-scion combinations in the greenhouse.1.Among the 11 rootstock-scion combinations of ‘Summer Black’,‘Summer Black’/SO4rootstock-scion combination has the highest environmental adaptability index,suggesting its strongest environmental adaptability.Among the 9 rootstock-scion combinations of ‘87-1’,‘87-1’/3309 C combination has the highest environmental adaptability index,suggesting its strongest environmental adaptability.2.Among the 11 rootstock-scion combinations of ‘Summer Black’,‘Summer Black’/140 Ru combination has the highest perinatal index,suggesting its perinatal time is the shortest;‘Summer Black’/5BB combination has the lowest perinatal index,suggesting its perinatal time is the longest.Among the 9 rootstock-scion combinations of ‘87-1’ grape,‘87-1’/kangzhen NO.1 combination has the highest perinatal index,suggesting its perinatal time is the shortest,‘87-1’/SO4 combination has the lowest perinatal index,suggesting its perinatal time is the longest.3.Among the 11 rootstock-scion combinations of ‘Summer Black’,‘Summer Black’/huapu NO.1combination has the highest new shoot labor-saving index,its inter-node length is short,new shoot growth rate is slow,the germination rate of the secondary shoots is low and management is the most labor-saving.On the contrast,‘Summer Black’/140 Ru combination has the lowest new shoot labor-saving index,its internode length is long,new shoot growth rate is quick,the germination rate of the secondary shoots is high and management is the most laborious.Among the 9 rootstock-scion combinations of ‘87-1’,‘87-1’/huapu NO.1 combination has the highest new shoot growth index,its inter-node length is short,new shoot growth rate is slow,the germination rate of the secondary shoots is low and management is the most labor-saving.‘87-1’/5C combination has the lowest new shoot labor-saving index,its inter-node length is long,new shoot growth rate is quick,the germination rate of the secondary shoots is high and management is the most laborious.4.Among the 11 rootstock-scion combinations of ‘Summer Black’,the soluble solid content of‘Summer Black’/101-14 M and ‘Summer Black’/kangzhen No.1 combinations are high,their vitamin C content are also high,their acid content are low.The single grain weight of ‘Summer Black’/SO4rootstock-scion combination is the biggest,the hardness of ‘Summer Black’/kangzhen NO.1rootstock-scion combination is the biggest,‘Summer Black’/5BB combination fragility is the biggest.According to the Topsis comprehensive evaluation method,the fruit quality index of ‘Summer Black’/1103 P combination is the highest and the quality is the best,but the fruit quality index of‘Summer Black’/140 Ru combination is the lowest,suggesting its quality is the worst.Among the 9rootstock-scion combination of ‘87-1’,the soluble solid content of ‘87-1’/kangzhen NO.1rootstock-scion combination is the biggest.The content of vitamin C of ‘87-1’/1103 P combination is the highest,panicle weight of ‘87-1’/3309 C rootstock-scion combination is the biggest.Single grain weight of ‘87-1’/5C combination is biggest,acid content of ‘87-1’/huapu NO.1 rootstock-scion combination is the biggest.Topsis comprehensive evaluation method was used to find ‘87-1’/1103 P rootstock-scion combination fruit quality is the best,‘87-1’/kangzhen NO.1 rootstock-scion combination fruit quality is the worst.5.Among the 11 rootstock-scion combinations of ‘Summer Black’,‘Summer Black’/huapu NO.1has the highest output index,suggesting its output is the highest.‘Summer Black’/140 Ru output index has the lowest output index,suggesting its output is the lowest.Among the 9 rootstock-scion combination of ‘87-1’,‘87-1’/huapu NO.1 rootstock-scion combination output index has the highest output index,suggesting its output is the highest.‘87-1’/SO4 rootstock-scion combination has the lowest output index,suggesting its output is the lowest.6.Among the 11 rootstock-scion combinations of ‘Summer Black’,the order of facility c ultivation suitability is: ‘Summer Black’/huapu NO.1> ‘Summer Black’/SO4> ‘Summer Black’/420A>‘Summer Black’/101-14M>‘Summer Black’/kangzhen NO.1>‘Summer Black’/3309C> ‘Su mmer Black’/5BB>‘Summer Black’/Beta>‘Summer Black’/140Ru>‘Summer Black’/1103P>‘Su mmer Black’/5C.Among the 9 rootstock-scion combination of ‘87-1’,the order of facility culti vation suitability is: ‘87-1’/SO4>‘87-1’/3309C>‘87-1’/huapu NO.1>‘87-1’/5C>‘87-1’/101-14M>‘87-1’/1103P>‘87-1’/Beta>‘87-1’/kangzhen NO.1>‘87-1’/140 Ru.
