蔗糖基聚合物对玉米呼吸作用和光合作用的影响

Effects of the Sucrose-based Polymers on the Rate of Respiration and Photosynthesis in the Leaves of Maize

试验用浓度为2%的蔗糖基聚合物水溶液在玉米各个生长期进行叶面喷施,研究其对玉米叶片呼吸作用及光合作用的影响。结果表明,蔗糖基聚合物能明显提高玉米叶片中的叶绿素含量,提高叶片的光合速率,同时降低叶片的呼吸速率和蒸腾速率,减少呼吸消耗,增加玉米子粒产量。

Sucrose-based polymers with concentration of 2% sprayed the leaves of different stages of maize. Effects of the sucrose-based polymers on the rate of photosynthesis and respiration were investigated. The results showed that sucrose-based polymers could increase chlorophyll content and the rate of photosynthesis of the leaves of maize, and decrease the respiration and transpiration rate at the same time.
