温度与花卉生长的关系一般花卉在其生长的适温范围内(10～25℃),温度升高,则促进细胞分裂和伸长,增加生长量。温度越高,光合作用越强,有机物的积累越多;同时呼吸作用也越旺盛。在10～35℃之间,温度每增加10℃,呼吸速率就增加2～2.5倍。温度与花卉开花的关系花卉的花芽分化都需要有一定的温度。一二年生草花必须经过一段低温期(即春化阶段)才能开花,如秋播草花必须经过10℃左右的低温才能形成花芽而后开花。梅花、玉兰、碧桃等花木多在当年开花后的6～8月间进行花芽分化,分化完后即进入休眠状况,经过一冬的低温期到翌春气温回升时自动解除休眠,然后花芽伸长继而开花。
The relationship between temperature and flower growth In general, the growth of flowers in its suitable temperature range (10 ~ 25 ℃), the temperature increases, then promote cell division and elongation, increase the amount of growth. The higher the temperature, the stronger photosynthesis, organic accumulation of more; the same time, the more vigorous respiration. Between 10 and 35 ° C, the respiration rate increases 2 to 2.5 times for every 10 ° C increase in temperature. The relationship between the temperature and the flowering of flowers Flower bud differentiation requires a certain temperature. First and second year old flowers must go through a period of low temperature (that is vernalization stage) to flowering, such as autumn sowing flowers must go through a low temperature of about 10 ℃ to form flower buds and then flowering. Plum, magnolia, bounty and other flowers and trees in flowering in June to August after the flowering bud differentiation, that is, after the differentiation into the dormant state, after a winter’s low temperature to the next spring temperatures automatically lift dormancy, and then flower bud elongation Then flowering.
