本研究证明,荔枝的果实及其各部分组织的鲜重和干重生长基本上都呈单S型。水分和溶质的进入,在前期基本上是同步的,没有明显的错开现象,但后期则往往出现不一致的情况,排除了果皮向假种皮转移贮藏养分的可能性。观察到溶质进入胚的速率高峰总是超前于进入假种皮,以及果实维管系统的分布有利于种子优先摄取养分,从而使胚的生长一度抑制假种皮生长的现象获得解释。假种皮的最终生长程度受到种子所占据的空间、假种皮细胞的溶质势和压力势三个因素的调节。
This study shows that the fresh weight and dry weight growth of the litchi fruit and its various parts of the organization are basically single S type. Moisture and solute entering in the early stage is basically synchronous, there is no obvious staggered phenomenon, but the late are often inconsistent situation, ruled out the peel to leave the possibility of the transfer of storage of seed coat. It was observed that the peak rate of solute entry into the embryo was always ahead of the entry into the pseudocapsule and the distribution of the fruit vascular system favored preferential nutrient uptake by the seed so that the growth of the embryo was suppressed once the growth of the seed coat was explained. The final growth of the aril is affected by the space occupied by the seeds, the solute potential and pressure potential of the pseudocapsule cells.
