the invention selects undeveloped leaves, stem segments and seed hypocotyls of dormant buds of schisandra chinensis as explants for inducing embryogenic callus, and uses the explants as comparative examples 1, 2 and 3 respectively, the influence of embryogenic callus induction when different parts of schisandra chinensis are used as the explants is researched, and culture steps which are not explicitly described in the comparative examples 1 to 3 are the same as the culture steps in the example 1.
Comparative example 1
Comparative example 1 provides a method for regenerating plants using unexpanded leaves of dormant buds of schisandra chinensis (schizandra sinensis) as explants, which is substantially the same as example 1 except that:
firstly, cleaning undeployed leaves of dormant buds with sterile water, soaking the leaves in 75% alcohol for 60s, washing with sterile water for 4 times, then placing the leaves into 0.1% mercuric chloride solution, standing for 10min, washing with sterile water for 5 times, and sucking water on the leaves for later use;
the rest of the cultivation steps and conditions were the same as in example 1.
Comparative example 2
Comparative example 2 provides a method for regenerating plants using stem segments of schisandra chinensis (schizandra sinensis) as explants, which is substantially the same as example 1 except that:
comparative example 2A stem section of Schisandra chinensis (Carthamus tinctorius) was used as an explant, the leaves of the young stem section of the upper half of the aseptic seedling were cut off, leaving only the stem section, the stem section was cut into 2-4cm pieces, and several cuts were made on the top with a scalpel, and the cut was sterilized and used.
Comparative example 3
Comparative example 3 provides a method for regenerating plants using hypocotyls of seeds of schisandra chinensis (schizandra androsaccensis) as explants, which is substantially the same as example 1 except that:
comparative example 3 the hypocotyl of the seed of schisandra chinensis (safflower) is used as the explant, and the early stage treatment is as follows: cutting the embryonic axis into 1-3cm segments, and cutting several knives thereon for inoculation.
As can be seen from the examples 1 and the comparative examples 1 to 3, the occurrence time sequence of the embryogenic callus is stem section > leaf section > undeployed leaf section, wherein the embryogenic callus which is visible to naked eyes appears at the incisions at the two ends after the stem section is inoculated for about 15 days, and then the embryogenic callus appears at the incision in the middle, the embryogenic callus is different in size, light yellow in color and loose in structure; the leaf blade is inoculated for about 15 days and begins to expand and curl, the embryogenic callus appears at the cut of the base part and the edge of the leaf blade for about 20 days, and then a thin layer of embryogenic callus appears on the surface part of the leaf blade, the color is light yellow green, and the structure is loose; the undeployed leaves begin to expand and curl about 20 days, embryogenic callus appears at the first edge cut in about 25 days, and the undeployed leaves are light green and green in color and loose in structure. As can be seen from Table 1, the embryogenic callus induced by the leaf and stem of the schisandra chinensis (Carthamus tinctorius L.) has good growth status, the embryogenic callus of the stem is early, the growth speed is high, and the embryogenic callus induced by the undeveloped leaf has relatively poor growth status;
TABLE 1 Effect of explant type on embryogenic Induction of embryogenic callus
Figure BDA0002488278020000091
The leaf and stem induced embryonic callus has good growth condition at the early stage, but in the late subculture process, a small part of the stem induced embryonic callus turns yellow brown, hard and compact.
Therefore, the leaf is the most suitable explant for inducing embryogenic callus, which is favorable for preserving excellent germplasm and better and directly obtaining excellent characteristics of a parent.
Compared with the invention, the comparison of different explants taken as comparative example regeneration plants shows that the growth conditions of the leaf and stem embryogenic callus induced by the leaf and stem are better and more, the embryogenic callus generation speed of the stem is high, but the browning is serious in the successive transfer process, the leaf browning is less, the number of leaf explants is more, the embryogenic callus generation speed of the unexpanded leaf is low, and the number of the embryogenic callus is less, so that the leaf is the most suitable explant for inducing the embryogenic callus.
The following comparative examples 4 to 6 were used to study the effect of exogenous plant growth regulator ABA on embryogenesis and development aberrations;
comparative example 4
Comparative example 4A method for regenerating plants from callus of Schisandra chinensis (Vaniot) is substantially the same as the step of example 1, except that:

in the step S3, the first step,
the No. 3 culture medium is based on an MS culture medium, is added with 0.2 mg/L2, 4-D +0.5 mg/L ABA and is not added with TDZ;
TABLE 2 Effect of exogenous plant growth regulator ABA concentration on embryogenesis and development
Figure BDA0002488278020000111
As can be seen from comparative examples 4-6, it is not easy to add TDZ and 2, 4-D to the MS medium during the embryogenesis, and the number of embryos is reduced; and the addition of ABA in the MS culture medium is beneficial to the improvement of the malformed embryos, greatly reduces the generation of the malformed embryos and is beneficial to the development of the embryos into seedlings (Table 2).
