摘要
对4个晚熟龙眼(DimocarpusLonganLour)品种的挂树期及其影响因素进行了观测研究,结果表明:晚熟龙眼挂树期长短与种脐大小、果皮及果蒂结构密切相关。果实的外表皮表面洐生物较多对挂树不利;果实表面蜡质多且连续,外果皮结构紧密、细胞排列有序、细胞间隙小,果蒂薄壁组织细胞排列均紧密,果实种脐小,有利于延长挂树时间。
Time of fruit keeping on plants and the influencing factors in four late maturing longan varieties were observed. The results showed that the time of fruit keeping on plants was related with the hilum size, pericarp structure and stem-end structure. Too much derivative on exocarp was a disadvantage to longan fruit keeping on plants, but plentiful and consecutive fruit surface waxiness was an advantage. Compact exocarp with orderly arranged cells and narrow extracellular space was helpful to prolong the time of fruit keeping on plants. Stem-end with compact parenchyma and small hilum were also helpful to prolong the time of fruit keeping on plants.
