LED Grow Light for Plant Tissue Culture
Plant tissue culture is a biotechnology, which is developed based on the plant cell totipotency principle. Over the years, several economically important plants have been multiplied and conserved using tissue culture technique in which whole plants are re-generated from parts of plants.
Early in the plant tissue culture research, people mainly focused on the study of plant culture medium composition. We know that various kinds of plants have different requirements of medium. The common culture medium are inorganic salt, hormones and organic matters. In recent years. With more and more research achievements in culture medium, people gradually turn to research the tissue culture conditions such as temperature, light intensity, air composition in the container and how these factors affect the quality and the speed of tissue culture.
lighting is an important condition in tissue culture. Atop Lighting Horti-spec single bar led grow light has been an very successful technique support for tissue culture .
Light intensity has an important influence on the proliferation of cultured cells and the differentiation of organs. According to the current research, light intensity has an obvious influence on the initial division of plant cells. Generally speaking, light intensity is strong and the seedlings grow strongly, while light intensity is weak and the seedlings tend to grow slender. There is no doubt that the light intensity tissue require is not as strong as that of robust plant.
Light quality also play an important role in the process of callus induction, proliferation of cultured tissue and organ differentiation. For example , when Lily tissues were cultured under red light. Callus generate after 8 weeks. However, when under blue light,callus appear after just several weeks. If culture calamus tissues in blue light. After 15 days, you will find seeding are in vigorous growth, while under white light, the seedlings are slender.
Study shows that monochromatic light has inhibitory effect on chlorophyll synthesis. The synthesis of chlorophyll needs to be done under the condition of compound light.
Along with the advance of technology, the development of LED grow light is quite rapid in recent years. As a new type of high efficiency and energy saving LED light source, LED grow light is becoming more and more common in the application of tissue culture. Because it features high efficiency, low energy, safety, reliability and durability. what’s more,the illuminated spectrum coincide with the requirement of plant photosynthesis.
Tube tissue cultivation should choose suitable photoperiod to conduct tissue culture. The most commonly used photoperiod is 16 hours in light, 8 hours in darkness. Research shows that plant organs of short-day plants are more likely to differentiate in short sunlight lighting condition. While under long sunlight, plant organs of short-day plants are more inclined to produce callus. Some plant callus cultured in dark condition is better than under the condition of light, such as the callus of safflower and blueberry. With the exception of some special plants, most general tissue cultures require a certain amount of light.
