Abstract
The invention provides a seedling strengthening and rooting culture medium of pear tree somatic embryos. The culture medium comprises 1/2 improved SH, 0.2-0.5mgL<-1> of 6-BA, 0.05-0.1mgL<-1> of 2,4-D, 0.1-0.15mgL<-1> of NAA, 6.0-7.0gL<-1> of agar and 30gL<-1> of sucrose and has pH value of 5.8-6.0. The culture medium has the beneficial effects that pear trees difficult to propagate are rapidly propagated through somatic embryogenesis by improving a basic culture medium and components and adjusting the culture conditions; the plant transplanting survival rate is more than or equal to 96%; seedlings grow robustly, thus the problem of germplasm degeneration of good seedlings can be effectively solved, plenty of high-quality purified and rejuvenated seedlings can be also provided for production and an ideal receptor system can be also provided for breeding new varieties through genetic transformation or mutation breeding of the pear trees.
Description
Technical field
The present invention relates to a kind of strengthening seedling and rooting medium of pear tree excised leaf, belong to botany field.
Background technology
Pear tree is rose family pear, perennial deciduous fruit tree, and arbor all has extensive distribution in the whole world, and about there are 35 initial specieses in the whole world, is wildly distributed in Europe, Asia and African, classification is divided into east pears and the large class of European pear two.Chinese pear area under cultivation and output are only second to apple.
Pear tree is a kind of seeds with higher Development volue, and at present, the modes of reproduction usually adopted is cottage propagation, and the fungal diseases such as this kind of modes of reproduction easy infection leaf spot, spring and summer, it was subject to again aphid damage, and its virus is serious, blade piebald easily comes off, and improved variety degree reduces; And the good characteristic that the use of seedling inferior causes pear tree intrinsic is lost day by day, this constrains the development of these seeds to a certain extent and applies, therefore, selection, breed good pear tree strain become a very outstanding production problem, tissue-culturing rapid propagation is a kind of effective way of pear tree breeding industrialization, the report of related fields is also more, but about the direct somatic embryos of Pears and regenerate fast numerous system technical research there are no successful report.
Summary of the invention
In order to overcome the deficiencies in the prior art, the object of the present invention is to provide a kind of can be effectively the strengthening seedling and rooting medium of the pear tree somatic embryo of the pear tree nursery stock that the amount of providing in production is of fine quality greatly, purificate and rejuvenate.
