Abstract


This paper was that technology of seedling propagation of Jujube, Walnut, Almond and Grape of characteristic fruits in south Xinjiang was studied. Tissue culture rapid propagation of Hui-zao Jujube was preliminary established. And studied on growing of tissue culture seedling effected by growth hormone. Studied on growing of grafed seedlings of Walnut and Almond effected by different graft methods and selecting best graft method. In test studied on factors of rooting of green cutting of Red Globe grape effected by ABT 1 power and selected optimal concentration of ABT1 power. The main results were as follows:1. In this experiment 0.1% HgCl2 was used as disinfectant and treatment explant. It showed that explants were washed in water for 30 minutes before putting in 75% alcohol for 30 s, and then the explants were disinfected for seven minutes in 0.1% HgCl2. This kind of treatment can achieve good disinfenction effect. The stem segments of Hui-zao Jujube were used as explants and carried out tissue culture. The result indicated that the optimal initial medium was MS+6-BA 0.8mg·L-1 +NAA0.1mg·L-1, multiplication medium was MS+6-BA 2.0mg·L-1+IBA 0.2mg·L-1 and rooting medium was 1/2MS + IBA 2.0mg·L-1+ NAA 0.3mg·L-1.2. The text was comparative study on different graft methods of walnut. The result indicated that survival ratio of“工”bud-grafting and single green branch grafting（83.4% and 82.4% respectively）are extremely remarkably higher than survival ratio of shield bud（78.5%）. But new tree top length and coarseness of shield bud and single green branch grafting are extremely remarkably surpass“工”bud-grafting . And new graft method of singal bud green wood grafting was hightest grafting efficiency. By comprehensive comparative analysis, the resulut was that singal bud greenwood grafting was best.3. Grafting experiment results of Almond showed that all investigation indexes of“T”bud-gtafting were the hightest. Seedling height（H）and base diameter（D）were proposed as indexes of quality. The standard of seedling grading of Almond was studied by using the method of gradual cluster analysis. Standard for classification can be follow as: GradeⅠ: 154cm≥H≥135cm, 1.36cm≥D≥1.21cm; GradeⅡ: 135cm >H≥117cm, 1.21cm>D≥1.04cm; GradeⅢ: H<117cm, D<1.04cm.4. Softwood cutting experiment of Red Globe grape indicated rootting rate was 100% when concentration of ABT 1 rooting power was 75mg·L-1 and root fresh weight and root quantity were all highest.
