果实的生长主要是指果实细胞的分裂和细胞体积的增大,有的还包括细胞间隙的增大。这些过程受多种内源激素的调节,已经证明,五类激素在果实的发育中都存在。下面分别讨论植物激素与果实细胞的分裂和果实细胞体积的增大的关系,举出一些外用植物生长调节剂促进果实生长的例子,并提出今后应用植物生长调节剂促进果实生长的可能途径。一、植物激素与果实细胞分裂已经发现,在未成熟的香蕉、桃、李、梨、榅桲和苹果的果实以及柠檬种子中、芒
Fruit growth mainly refers to fruit cell division and cell volume increases, and some also include increased cell gap. These processes are regulated by a variety of endogenous hormones and it has been shown that all five hormones are present in fruit development. In the following, the relationship between plant hormones and fruit cell division and the increase of fruit cell volume are discussed respectively. Some examples of the application of plant growth regulators to promote fruit growth are also discussed. The possible ways of applying plant growth regulators to promote fruit growth are also proposed. First, plant hormones and fruit cell division has been found in immature bananas, peaches, plums, pears, emus and apple fruit and lemon seeds, Mount
