荔枝开花与正常成花诱导期的休眠程度密切相关。低温和缺水看来会限制营养生长,并促进花蕾形成。但是也有许多例外的情况,因此可列举出各种因素(结果量、植株营养等)相互作用的例子。业已证实,缚扎枝条(环割)和外源生长素可抑制营养生长和提高开花率,但结果不甚一致。提高开花率最理想的前景,看来是选择能适合于比原产地中国的自然环境更温暖、潮湿的条件下开花的基因型(或许是长势不旺的基因型)。一种可供选择的方法,是深入研究在非诱导条件下,能限制营养生长,并促进营养生长休眠的处理技术,即缚扎枝条、施用生长抑制剂以及控制灌溉和施肥。
Lychee flowering is closely related to the degree of dormancy during the induction of normal flowering. Low temperatures and water scarcity appear to limit vegetative growth and promote flower bud formation. However, there are many exceptions, and examples include the interaction of various factors (amount of results, plant nutrition, etc.). It has been demonstrated that binding of shoots (ring mowing) and exogenous auxins can inhibit vegetative growth and increase flowering rates, but the results are less consistent. The best prospects for increasing flowering rates appear to be to select genotypes that may be suitable for flowering under warmer, wetter conditions than the natural environment of the country of origin (perhaps a growing genotype). An alternative approach is to delve into treatment techniques that limit vegetative growth and promote dormancy of vegetative growth under non-induced conditions, ie tie the branches, apply growth inhibitors and control irrigation and fertilization.
