- Abstract:
- Following the summer heat is studied under different root temperature processing of tomato plants growth and the impact on the stomata，to delve into the different root temperature treatment on the influence of tomato leaf microstructure.Taking tomato as material,using the nutrient cycle cultivation，three treatmeats of （23±1）℃，（28±1）℃ and（33±1）℃ were done，the microstructure of leaf was observed and measured by the method of paraffin section.The results showed that with the increase of root temperature，plant leaf thickness,palisade tissue thickness,sponge tissue thickness were decreased；epidermis thickness,the thickness of palisade tissue/spongy tissue increased.So the root of high temperature on plants constituted the drought stress，plants changed the structure characteristic of itself in order to meet the environment of high temperature and drought.
