摘要:
 通过对盆栽的1年生刺槐（Robinia pseudoacacia）幼苗进行为期8周的适宜水分、中度和重度干旱3个土壤水分梯度(分别为田间持水量的(70±5)%、(50±5)%和(35±5)%)处理，研究不同土壤含水量对刺槐叶片光合能力及碳水化合物在不同器官中分配的影响。结果表明：1）随着土壤含水量减少，刺槐叶片的净光合速率及光合能力逐渐降低；2）叶、茎干和细根的生物量显著减少，粗根的生物量也表现出降低的趋势，但根苗比增大；3）叶片中可溶性糖含量保持不变，但淀粉含量显著减少，同时，茎干、粗根和细根中可溶性糖和淀粉含量均升高；4）可溶性糖和淀粉的总量在叶片和茎干中显著减少，在粗根和细根中也表现出下降的趋势。说明在干旱条件下，刺槐光合能力降低，有限的碳水化合物优先分配给非光合器官，特别是根系，引起根苗比的增大。
Abstract:
 In order to examine the effects of soil water contents on leaf photosynthesis and carbohydrate partitioning in different plant organs, one-year-old Robinia pseudoacacia seedlings were planted individually in pots and exposed to three soil water contents (suitable water condition, medium drought, and severe drought, corresponding to soil water contents between(70±5)%,(50±5)% and (35±5)% of field water capacity, respectively) for eight weeks. The results showed that under decreased soil water contents, 1) leaf net photosynthetic rate and photosynthetic ability reduced; 2) biomass of leaves, stem, and fine roots reduced significantly, while biomass of coarse roots tended also to reduce, however, in result, the rate of roots to shoot increased; 3) soluble sugar contents in leaves were not affected by soil water contents, but starch contents reduced significantly, whereas in stem, coarse and fine roots the contents of soluble sugar and starch increased; 4) the total contents of soluble sugar and starch in whole leaves and whole stem of individual plant decreased significantly, also tended to reduce in coarse and fine roots. In conclusion, under reduced soil water contents, leaf photosynthesis ability reduced, and limited carbohydrates were preferentially partitioned to non-photosynthetic organs, resulting in an increase in the rate of roots to shoot.
