Coupling effects of light and temperature on growth and seedling quality of cherry tomato
Abstract：Light and temperature are important conditions for plant growth and development, in a controlled environment, grasp the light temperature ratio parameter to a reasonable and effective regulation of cherry tomato growth and quality, achieve the high yield and high efficiency. In this experiment, the cherry tomato "Millennium" as the material, the research intensity in the 300 μmol m-2 s-1, a temperature of 25±1℃(G2T1); 250 μmol m-2 s-1 light intensity, temperature 28±1℃ (G1T2) effect on Cherry Tomato Seedling Growth and seedling quality of the two parameters were found: compared with G1T2, G2T1 treatment of cherry tomato seedling stem diameter, leaf area, the length of the first internode, on the ground the fresh and dry weight, underground fresh and dry weight, total dry weight and fresh weight, seedling index has improved significantly; the net photosynthetic rate, chlorophyll a, chlorophyll b, chlorophyll (a+b) content and chlorophyll a/b had no significant change; but G1T2 carotenoid content increased significantly. Compared with G2T1 ensemble Considering all factors, under controllable environment, the light intensity is 300 μmol m-2 s-1, and the temperature is 25±1℃, which is more conducive to the growth of cherry tomato and the improvement of seedling quality.
