中华猕猴桃系藤本果树,枝蔓缠绕、纵横交错,叶片大、徒长枝多,使树冠郁闭、通风透光不良,旺盛的营养生长常常限制了同化产物向生殖器官的运输,从而导致落花落果,影响花芽形成,严重地影响果品产量和品质。许多研究证明,光合产物的运输是受激素控制的。大量报道认为,B_9、PP_(333)有提高座果的作用,而CEPA具有诱发果实脱落的作用。因此,我们推想可能和光合同化产物的调配有关。所以利用放射性C~(14)研究了生长抑制物质对C~(14)—光合同化产物调配的影响。材料和方法试验于1985年5月中旬至6月中旬在西北农业大学同位素实验室进行。供试材料为4
Chinese Actinidia is a vine fruit tree, branches and intertwined, criss-crossing, large leaves, long branches and more, the canopy canopy closed, poor ventilation and ventilation, strong vegetative growth often limits the assimilation products to the reproductive organs of transport, leading to the fall and fall, the impact Flower bud formation, seriously affecting fruit yield and quality. Many studies have shown that photosynthate transport is hormone-controlled. A large number of reports that, B_9, PP_ (333) have to improve the role of fruit, and CEPA has induced fruit shedding effect. Therefore, we speculate that it may be related to the formulation of photosynthetic products. Therefore, the effect of growth inhibiting substances on the distribution of C ~ (14) - photo assimilation products was studied by radioactive C ~ (14). Materials and Methods Experiments were conducted at the Northwest Agricultural University Isotope Laboratory from mid-May 1985 to mid-June. The test material is 4
