Research on the Effects of Drought Stress at Different Stages of Chrysanthemum Growth and Development
In this paper,the effects of drought stress on the growth and development of chrysanthemum and its seeds were studied by adopting the method of controlling water by pot culture(soil culture).The results showed that the germination rate,germination potential and germination index of chrysanthemum seeds decreased with the intensification of drought stress;the plant height,root length and dry matter quality of chrysanthemum seedlings showed a decreasing trend.With the intensification of drought stress,the growth and development of chrysanthemum plants were inhibited,and the ornamental value of chrysanthemum plants decreased significantly.Experiments show that the basic growth needs of chrysanthemum can be satisfied by watering it once every 6 days with the pot-culture method.
