In Guizhou Province, systematic investigation and gathering of wild grape species on the basis of resources, originating in Guizhou wild species Vitis species distribution, introduction and preservation, site conditions, biological characteristics, reproductive characteristics and utilization of fruit quality analysis and the use of evaluation research, mainly to obtain the following results: 1 Guizhou Province Wild Vitis rich germplasm resources, the study found that the 10 kinds and two undetermined species, namely Vitis, stockwork grapes, cotton wool grapes, Vitis, beautiful grapes, grape leaf birch, glandular branches of grapes, grape fengqing, Yunnan grapes, East grapes, Aung Aung 14 # and Aung Aung 15 # . Geographical distribution and the distribution of different types of different densities, which Vitis most widely distributed, highest density, followed by glandular branches of grapes, distribution least in East grapes and Aung Aung undetermined species 15 # . From the geographical distribution point of view, the most abundant species Qiannan distribution, a total of eight kinds, and two undetermined species. 2 Guizhou Wild Vitis Species ability to adapt to a different environment, in which East grapes and Aung Aung 15 # , Aung Aung 14 # Habitat demanding; while gross Grape ability to adapt and adapt the scope of the soil is also very broad. 3 Guizhou wild grapes can available nitrogen, organic matter, total N, available phosphorus and boron content effectively grown on different soils; different site conditions different wild species, its native soil nutrient content are quite different kinds of different single strain differences in site conditions exist, especially in organic matter, available N, available P content on the difference more obvious. Vitis on soil available N and available P content requirements and glandular branch of grapes on a wide range of soil organic matter content requirements; Vitis huishui 1 # , Qianling 2 # and glandular branches of grapes Fanjingshan 6 # , Ray Hill 5 # in the soil relatively barren area planted and utilization. 4 different grape varieties and wild species of wild grapes with different biological characteristics of different strains. Diurnal variation of net photosynthetic rate is divided into \Grapes> Beautiful Grapes> Yunnan grapes> Aung Aung 14 # > Aung Aung 15 # . The same species there are also differences between different plant, the average daily net photosynthetic rate than the crystal strains followed Vitis HUAJIANG 2 # > HUAJIANG 3 # > XIAOQIKONG 1 # > Nishiyama 7 # > HUAJIANG 1 # > Agriculture 3 # > Huaxi 9 # > Ding cans City 1 # > Agricultural School 11 # > Administrative Building 2 # > HUAJIANG 10 # > Crystal; daily average net photosynthetic rate is higher than the crystal stockwork grape strains were: Dongpo 9 # > Nishiyama 42 # > Dongshan 28 # > Nishiyama 39 # > Crystal; daily average net photosynthetic rate is higher than the crystal grape strains glandular branches were: XIAOQIKONG 4 # > Small seven holes 5 # > MAOLAN 7 # > Fanjingshan 5 # > Crystal. The growth potential of wild grapes there are also differences, including Vitis lines Huaxi 4 # and farm homes 11 # , glandular branches grape strains XIAOQIKONG 5 # , stockwork grape strains Dongpo 1 # shoots better performance in the growth process. 5 Wild Vitis Seed germination rate naturally low, less than 25%, and the use of exogenous GA 3 treatment can improve the germination rate of wild species of grapes, but a different kind on the GA 3 ability to respond to different branches of which thorn vines and grapes with glandular 250m (?) L ? of GA 3 best effect, the germination rate reached 45.70% and 45.00%. Wild Grape seed germination process, its metabolic inclusions provide energy for seed germination and nutrition, but different species of wild grapes, their different metabolic inclusions which Vitis lowest carbohydrate content, and the metabolism of the most slow; thorn vines and grapes branch gland metabolism of carbohydrates similar. 6 hardwood cuttings of wild grapes Even with ABT treatment, the survival rate is very low, and the different types and different strains of the same species differences exist between the highest branches gland grapes MAOLAN 6 # (28.57%); followed Vitis Fanjingshan 3 # (23.81%); while the majority of species and strains of wild grapes rooting difficulties, cuttings difficult to survive. 7 different species of wild grape vine grafting affinity with crystal differences, where the highest survival rate Vitis grafting (69.23%), Vitis minimum (10.00%); Vitis cultivars with different affinity between the grafted also there are differences, of which the highest survival rate of ultra-vine (93.33%), the highest degree of crystal lignification year (4.30). 8 Guizhou wild grapes ear smaller, lighter weight of single, but some strains (Vitis Tian Tan 2 # ) yield per plant is very high, higher soluble solids; Some species The reducing sugar content, soluble sugar content can be comparable with the cultivar.
