硅对水稻叶片光合特性和超微结构的影响
Effects of Silicon on Rice Leaf Photosynthesis and Ultrastructure
摘要
Abstract
To further investigate nano-silicon on rice growth, using "nongda 19" as material, by spraying nano-silicon and sodium silicate, the chlorophyll content of flee leaves, peroxidase (POD) activity, net photosynthetic rate (Pn), stomatal conductance (Gs) and intercellular CO2 concentration (Ci) were measured. Simultaneously, surface uhrastrueture of rice leaves and Si element content of flee leaf surface were determined and analyzed. The results indicate that application of silicon to rice can increase chlorophyll content, stomatal conductance and net photosynthetic rate, thereby enhance the photosynthesis of leaves; Application of silicon to rice can be conducive to formation of silicified leaf cells and enhance the content of silicon on leaf surface and leaf photosynthesis, but too large silicon will reduce chlorophyll content and net photosynthetic rate. Through comparing between concentration of SiO2 hydrosol and sodium silicate, application concentration of 80 mg/L of Si02 hydrosol was found to be the best result.关键词
