What are the control measures for flower tissue culture conditions? The regulation measures of flower tissue culture and seedling environment mainly include temperature, care, humidity and gas. When carrying out tissue culture and seedling cultivation, it is necessary to pay attention to these four points. The specific small series will be explained in detail below. I hope everyone will Can help.
First, the temperature
(1) The temperature of the plants that cultivate the native tropics must be controlled within the range of 26-27 degrees. In the cold area, the plant temperature should be controlled at 20-23 degrees, and the temperature is generally controlled at 23-27 degrees to adapt to the vast majority. plant growth.
(2) The night is a few degrees lower than the daytime, for example, the daytime temperature is 25 degrees, and the nighttime temperature is 15 degrees, depending on the type of flower.
(3) Conditional can establish a natural light culture room, which is conducive to the growth of seedlings and robust growth.
Second, the light
(1) Illuminance
The growth of the shoot tip of the plant and the subculture of the seedling need to be carried out in a light environment, and most types of illumination are controlled at 1000-3000 lx;
When the plants are rooted, the light is controlled in the range of 300060001x, and gradually increases to 10001x before the seedlings are removed.
(2) Spectral
There are three kinds of spectra: ultraviolet light, blue light, and red light.
Ultraviolet light and blue light energy can effectively promote the differentiation of plant buds;
Red light can promote the formation of plant roots and can be regulated with different light at different stages.
(3) Lighting time
Long-day plant illumination time should be more than 12 hours, while short-day plant care time is less than 12 hours.
Third, humidity
In particularly dry areas or very dry seasons, it is necessary to keep the relative humidity of indoor air in the range of 70-80%. It is necessary to avoid too much water loss in the medium, especially when cultivating long-term woody flowers in the growing season. Based on dryness.
Fourth, the gas
(1) In the sugar-free medium, carbon dioxide as a carbon source can effectively reduce microbial contamination and facilitate better plant growth, but the carbon dioxide in the container is insufficient to meet the growth of the seedling, so human input is required;
(2) For those cultivated plant larvae, ethylene will be produced, and if it is in a sealed bottle, it should be treated to avoid harmful gases from harming the plant itself.
