为探究黄瓜双断根嫁接苗合适的贮藏时间，对不同时间贮藏处理后嫁接商品苗成活率、生理和形态指标进行了研究。在20℃黑暗高湿（99%）条件下，对黄瓜双断根嫁接苗进行0（对照）、4、8、12、16、20、24、28、32、36、40、44、48 h不同时间贮藏。试验结果表明，黄瓜断根嫁接苗在贮藏48 h后，虽然保持较高的成活率（98.50%），但植株的壮苗指数、植株干质量、地下部干质量、真叶可溶性糖含量、根表面积、根长和根体积等指标与贮藏40 h的嫁接苗存在显著差异。说明在20℃黑暗高湿环境下，在保证黄瓜双断根嫁接苗成活以及商品苗质量的前提下，贮藏时间应控制在40 h以内。

s:In order to investigate the suitable storage time for the root-cutting grafted cucumber seedling, this experiment studied the effects of different storage times on the survival rate,morphological and physiological indexes of commercial seedlings of root-cutting grafted cucumber(Cucumis sativus L.).Under 20 ℃,in darkness and high relative humidity(99%),we compared the effects of storage times including 0(control),4, 8,12,16,20,24,28,32,36,40,48 hours,respectively on root-cutting cucumber grafted seedlings. The results indicated that the treatment of 48 hours,in spite of high survival rate(98.50%),showed significant differences with 40 hours treatment in the following terms of dry weight,root dry weight,seedling index,soluble sugar of true leaf,absorption area,volume of rootand root length compared.These results also indicated that under 20℃,in darkness and high relative humidity,the suitable storage time should be controlled within 40 hours to assure the high survival rate and good quality of commercial seedlings of root-cutting grafted cucumber.
