| 摘要: |
| 以春季日光温室的光温环境为对照,与冬季进行比较研究。结果表明在冬季低温寡照逆境中,黄瓜叶片光合产物的输出率及向果实中分配的比例减少,而向茎中分配的比率增加。无论冬季或春季,黄瓜光合产物绝大部分在白天输出,冬季夜间输出只限于盖苫后2h 以内。品种间比较,农大14在冬季光合产物输出率高,向茎及其他器官分配比例也多。 |

| Abstract: |
| The influence of light and temperature in winter in solar greenhouse on the transportation and distribution of cucumber assimilation products was studied,by comparing with that in spring.Results are as follows:The poor light and low temperature in winter reduced the assimilates expot rate,decreased the carbon distribution to fruits but increased that to stems.The export of cucumber assimilating products was mainly in the daytime no matter in winter or in spring,and the export during winters night was just w... |
| Key words: solar greenhouse cucumber assimiltion prodacts transport distribution |
