Generally speaking(10 gallon nursery pots wholesale), the flowers originated in tropical climate type have higher requirements for temperature, and they can't bear low temperature, otherwise they will suffer from low temperature. After the seedlings are unearthed, the temperature should be slightly lower to prevent the seedlings from growing too long(v12 nursery pots). Low temperature is the most taboo of the genus Calamagrostis.

If photosynthesis is inhibited, chlorophyll is destroyed, and the color of leaves turns yellow and brown(1 gallon nursery pots wholesale). Therefore, in the cultivation of such flowers, only in the medium temperature or high temperature environment can the growth and development of normal(nursery tray price). The highest temperature that can be tolerated varies with the species and origin of flower waste. Wang Lian and tropical water lily require higher temperature.
(cheap plastic plant pots wholesale nigeria)Most biennial flowers need to go through the vernalization stage after a period of low temperature of 1 ~ 5 ℃ in seedling stage(15 gallon nursery pots wholesale), otherwise, flower bud differentiation can not be carried out, so it can not bloom normally. The optimum temperature for the growth of Alocasia macrocephala was 28 ~ 18 ℃(propagation trays for cuttings). If the environmental temperature is lower than 15 ℃, the leaves will curl, shrink, and even fall off.
When plants enter vegetative growth, higher temperature is needed to promote vegetative growth, which is conducive to the accumulation of nutrients(3 gallon nursery pots wholesale). In addition to the above flowers, brandy, tropical orchid, cabbage, goldfish enzyme, Guangdong evergreen, star point evergreen, Douban green, Xilin taro and other flowers also like higher temperature(elfin thyme plug tray). This is often used in flowering control practice.(cheap plastic plant pots wholesale nigeria)
In addition, flowers are also vulnerable to high temperature during flowering and fruiting period(20 gallon nursery pots wholesale). This is because this kind of flower must go through a period of low temperature stimulation, in order to turn into reproductive growth stage. For example, the room temperature should not be lower than 15 ℃ in winter(9cm plastic grow pots), the leaves appear burn and necrosis spots, such as Alternanthera alternifolia and Tongfeng pear.
(cheap plastic plant pots wholesale nigeria)Temperature also has a great influence on the normal flowering of most woody flowers, such as plum blossom, Magnolia, green peach, Haitan, etc(5 gallon nursery pots wholesale). these flowers and trees usually undergo flower bud differentiation from June to August after flowering in the current year, and enter into dormancy after the differentiation is completed(mushroom growing trays). If the winter temperature is lower than 5 ℃, they can be killed in a short time.
Among them, the taro and the rose taro have higher requirements on temperature(128 cell seed trays wholesale): taro and HuangJinGe (green Luo) grow poorly below 10 ℃, and even yellow leaves and fallen leaves appear. When the temperature exceeds the upper limit of the flower temperature, white taro(72 plug tray), turn yellow, the flower will be damaged by high temperature and many physiological abnormal phenomena will appear.(cheap plastic plant pots wholesale nigeria)
In general, the response of leaves to high temperature is the most sensitive(7 gallon nursery pots wholesale), and the leaf surface temperature can be more than 10 ℃ higher than the temperature under strong light, so the leaves are most vulnerable to high temperature. The causes of high temperature damage to flowers can be divided into direct causes and indirect causes(4.72inch plastic nursery pots). For most flowers, the highest temperature is between 35 ℃ and 40 ℃.
