柑桔树通常抽生无叶花序,无叶花序以后可以成为无叶结果枝。根据许多报道,无叶花序极少座果。例如,Lenz等(1969)曾把华脐的花序分成4种类型(即有叶单花A.无叶单花B;有叶花序C.无叶花序D),并研究了花的发育和这4种类型花的座果情况。他们的观察表明,尽管花序上叶片的分化延迟了花的发育,但在以后又有利于花果的生长。这就是为什么果实几乎都着生在有叶花序 Citrus trees usually pump leafless inflorescences, non-leaf inflorescence can later become non-leaf fruiting branches. According to many reports, leaves rarely inflorescence fruit. For example, Lenz et al. (1969) classified inflorescences of the umbilical cord into four types (ie, leafy single flower A. leafless single flower B; leafless flower C. leafless inflorescence D) and studied flower development and 4 kinds of flowers of the fruit situation. Their observations show that, although the differentiation of the leaves on the inflorescence delayed the development of the flower, it later favors the growth of the fruit. This is why almost all fruits are born in the leaves
