Dynamic Changes of Physiological Metabolism in Chrysanthemum Induced by Photoperiod During Flowering
Abstract: This paper studies the light in different period (a group for a 1 month of shading 15 hours a day, while the control group normal daylight conditions do not do any processing) after treatment, according to the chrysanthemum in its metabolites qualitative change happened in the process, to determine the photoperiodic flowering chrysanthemum. Experiment is by measuring the chrysanthemum flowering process (including beginning flowering, early flowering, coated, out of four periods) in leaves is a reducing sugar, soluble protein, starch and other metabolic substance content changes to your conclusions. Experiments, after dealing with the shorter of the experimental group than the control group of chrysanthemum into full bloom, 16 days in advance according to the same time found short day treatment after experimental analysis with the blade of chrysanthemum leaf can reducing sugars, starch content is relatively low, and the content of protein is relatively a bit higher. Through these experimental data, we can determine the photoperiodic effects on chrysanthemum flowering, out light cycles can induce chrysanthemum flowering and photoperiod changes affect chrysanthemum leaf metabolites qualitative conclusion, according to the research conclusion to achieve the goal of regulating the chrysanthemum flowering.
