作者在浙南以“元红”为试材,经石腊切片观察表明,荔枝的花芽形态分化宜分为花序原基分化始期以及主序、多级侧序、花萼、雄蕊和雌蕊等6分化时期。10月底出现花芽形态质变,花序原基开始分化,11月至翌年3月是主序和多级侧序分化期,1至4月为花萼分化期,雄蕊分化期集中于4月上、中旬,雌蕊分化期集中于4月中、下旬。低温主要影响主序和多级侧序分化期的延长。
In southern Zhejiang Province, “Yuanhong” was taken as experimental material. The observation of paraffin section showed that the flower bud differentiation of litchi should be divided into the initial stage of inflorescence primordium differentiation and the differentiation of main sequence, multilevel sequence, calyx, stamens and pistil period. At the end of October, flower bud morphological changes occurred, inflorescence primordia began to differentiate, from November to March next year was the main order and multi-stage differentiation, from January to April for the calyx differentiation, stamen differentiation concentrated in April, mid, Pistil differentiation concentrated in mid-April, late. Low temperature mainly affect the main sequence and multi-level sequence of the extension of the differentiation.
