Can the orchid of tissue culture become old kind, the advantage of tissue culture orchid and disadvantage introduction

There are two ways to propagate avocado, one is sowing and the other is grafting. Sowing is usually done in the spring. Soak in water for a day before planting, and then seal and moisturize for germination. After budding, it is planted in a loose and fertile seedbed, and then transplanted when it grows to 15-30 centimeters. Grafting is mostly selected from Mexico as rootstock, West Indian or Guatemala as scion, bud grafting, cleft grafting and close grafting can be carried out.

1. can you change

You can't become an old breed.Old seed refers to the offspring seedlings obtained by completely propagating in the natural environment, which can better maintain the characteristics of the original seed.The tissue culture seedling is a complete plant regenerated from the mother plant by artificial culture under aseptic conditions.Therefore, tissue culture seedlings can not become old seeds.Although both of them use the mother plant to propagate, the difference is still relatively large.The roots of tissue culture will be whiter, thinner and smoother than those of the old ones.

Advantages and Disadvantages of Tissue Culture

1. Advantages: Tissue culture orchids can make some precious orchids get a lot of reproduction.In addition to the cheaper price, it can make many precious varieties of orchids into ordinary people's homes.It can also meet the growing demand for orchid seedlings in the market, otherwise only wild flower seedlings can not meet the needs of the public.Secondly, tissue culture orchids can be concentrated to cultivate exactly the same orchids, their color and leaf shape will not be different.In addition, virus-free seedlings can be obtained by tissue culture.

2. Disadvantages: higher difficulty of breeding.Because tissue culture orchids are cultured in a sterile environment, temperature and humidity are strictly controlled.Therefore, its resistance is relatively poor, the temperature and humidity requirements are relatively high, and it is not resistant to diseases.That is to say, it is much more delicate than wild orchids.The flower of tissue culture orchid is easy to degenerate, and the leaves will be shorter, and it is not easy to blossom.The growth of tissue cultured orchids is unstable, and the problems of short and thin leaves, difficult flowering, falling seedlings and light fragrance are prone to occur.In addition, the color and leaf shape of tissue culture orchids will not change, lacking the beauty of personality.Few wild orchids are exactly the same, even if the same species of orchids in the same mountain, because of the different growth sites, there will be slight differences.
