成块作用通常被孤立地研究,而未考虑到这是将碳水化合物输往地下贮藏器官的诸生理过程的总综合。成块作用和同化物的分配是不可分割的二个过程,它们受所有已知内源激素的控制。赤霉素通过调节地上茎枝的生长速度间接地影响成块过程。细胞分裂素、生长素和脱落酸,看来是通过控制细胞分裂和细胞扩大来决定块的库活性。已发现乙烯能影响成块作用,但尚不清楚其作用部位。近来研究表明, Blocking is often studied in isolation, without considering that this is the total synthesis of the physiological processes that transport carbohydrates to underground storage organs. Blocking and assimilation are two indivisible processes that are controlled by all known endogenous hormones. Gibberellin indirectly affects the lump formation process by regulating the growth rate of shoots on the ground. Cytokinins, auxins and abscisic acid appear to determine the library activity of the block by controlling cell division and cell expansion. It has been found that ethylene can affect agglomeration but it is unclear where it is applied. Recent research shows that,
