- 摘要:
- 以山杏（Armerniaca vulgaris Lam）叶片为试材，叶面喷施外源一氧化氮（Nitric Oxide，NO）供体硝普钠（Sodium Nitroprusside，SNP），研究其对杏叶片净光合速率（Pn）、蒸腾速率（Tr）、胞间CO2浓度（Ci）以及叶绿素含量的影响。结果表明，在一定浓度范围内，杏叶片Pn、叶绿素含量随处理浓度的升高而增加，其中以100μmol/l处理最高。SNP处理后，叶片的Tr均低于对照而Ci均不同程度有所升高。
- Abstract:
- Experiment was conducted with the leaves of apricot tress. The effects of exogenous nitric oxide on the net photosynthetic rate (Pn), transpiraton rate (Tr) and chlorophyll content were studied after spraying the exogenous nitric oxide (sodium nitroprusside, SNP) on the leaves. The results showed that, within certain concentration, the Pn and chlorophyll content of leaves were raised along with the treated concentration increased. 100 μmol/l was the best one increased the Pn and chlorophyll content. Comparing to the control, the Tr was decreased and Ci was increased.
