葡萄果实以来自根部的无机盐、水分和来自叶片的光合产物作为营养原料,在消耗与积累的矛盾运动中生长发育。在此生长发育过程中,经常可见第一期与第二期的果粒变形和大小不一的现象,第三期又往往有成熟延迟及干物质积累不足的情况发生。一般认为,造成这种后果的原因之一是,营养物质往果粒的输送量不够以及果穗与其它营养 Grape fruit grows and grows in the contradictory movement of consumption and accumulation with inorganic salts, water and photosynthate from the roots as the raw material of nutrition. In this process of growth and development, we can often see the first and second phase of the grain deformation and size of the phenomenon, the third phase often have maturity delay and lack of dry matter accumulation occurs. It is generally accepted that one of the reasons for this is the lack of delivery of nutrients to fruit grains and the combination of ear and other nutrients
