菊花为短日照植物,在短日照下能提早开花。喜阳光,忌荫蔽,较耐旱,怕涝。

Chrysanthemum is a short-day plant, which can bloom early under short-day sunshine. Like sunshine, avoid shading, more drought tolerant, afraid of waterlogging. I like the warm and humid climate, but also tolerant, the roots can overwinter underground in severe winter season. The flowers can withstand the slight frost, but the seedling growth and branching buds need a higher temperature. The optimal growth temperature is about 20 ℃. Low temperature is one of the important factors that restrict the geographical distribution and production of chrysanthemum. Under low temperature stress, the plant membrane system is damaged, resulting in changes in related physiological indicators. Chrysanthemum production often suffers from overwintering injury and causes huge economic losses. Despite optimizing cultivation measures and improving cultivation conditions, the cold resistance of chrysanthemum can be improved. Osmotic adjustment substances are mainly soluble sugar, soluble protein, proline and so on. By studying the effect of low temperature stress on osmotic adjustment substances in chrysanthemum leaves, the cold tolerance of chrysanthemum can be improved and the yield of chrysanthemum can be further improved.

Chrysanthemums are short-sunplants that can flower early in short sunlight. Happy sunshine, shade, more drought-tolerant, afraid of flooding. Happy warm and humid climate, but also can withstand the cold, strict winter root can be in the underground winter. Flowers can withstand microfrosts, but seedlinggrowth and branching require higher temperatures. The optimum growth temperature is about 20 degrees C. Low temperature is one of the important factors to limit the geographical distribution and production of chrysanthemums, and the plant membrane system is injured under low temperature stress, which leads to the change of relevant physiological index. Chrysanthemum production often suffers huge economic losses due to winter injuries, although the optimization of cultivation measures, improved cultivation conditions can improve the cold resistance of chrysanthemums. Osmosis regulating substances are mainly soluble sugars, soluble eggs, proline and so on. By studying the effect of low temperature stress on the permeation and regulating substance of chrysanthemum leaves, the cold resistance of chrysanthemumcane can be improved and the production of chrysanthemum can be further improved.

Chrysanthemum is a short sunshine plant, which can bloom early under short sunshine. Like sunshine, avoid shade, more drought tolerance, fear of waterlogging. I like warm and humid climate, but I can also endure it. In severe winter, rhizomes can survive underground. The flower can endure frost, but the temperature is higher for seedling growth and branch bud formation. The optimum growth temperature is about 20 ℃. Low temperature is one of the important factors limiting the regional distribution and production of chrysanthemum. Under low temperature stress, the membrane system of plants is damaged, resulting in the changes of related physiological indexes. Chrysanthemum production often suffers from overwintering injury and causes huge economic losses. Although optimizing cultivation measures, improving cultivation conditions can improve the cold resistance of chrysanthemum. Osmoregulation Substances are mainly soluble sugar, soluble egg self, proline and so on. By studying the effect of low temperature stress on osmoregulation of chrysanthemum leaves, the cold tolerance and yield of chrysanthemum can be improved.<br>
