The invention provides an anther-stirring, pollen-collecting and hybrid pollination method of tobacco by using an artificial pollination pin. The method comprises specific steps that: during 8:00am to 10:00am or 4:00pm to 6:00pm, flowers of tobacco plants in post pollen tube growth periods are cut off and stored; flowers in blooming periods or blossom periods are selected as female parent flowers; during 8:00am to 9:00am or 5:00pm to 6:00pm on a sunny day, anther-stirring, pollen-collecting and hybrid pollination are carried out by using a pollination pin. According to the invention, male parent stamens and female parent pistils are in periods with optimal activities and affinities, such that pollination effect and seed quality are effectively improved; pollens in two pollen sacs of one anther are respectively used for pollinating two female parent flowers, and five anthers of a male parent flower can be used for pollinating 6 to 10 female parent flowers, such that a large amount of male parent pollens are saved, and the plantation amount of male parent tobacco is reduced; the pollination device is easy to manufacture and convenient to use, and the pollination method is simple, such that the seed yield is greatly improved, and the comprehensive cost of seed production is reduced. Therefore, the method is suitable to be applied in tobacco hybridization scientific experiments and tobacco large-area hybrid species propagation and production.

The invention discloses a method for flowering test-tube plantlets of Chinese roses in a test tube and carrying out pistil monosexual flowering and a culture medium thereof. The method comprises the following steps: (1) obtaining rootless test-tube plantlets through subculturing; (2) flowering diploids of the rootless test-tube plantlets of Chinese roses in the test tube; and (3) carrying out induced-flowering on pistils of the diploids of the rootless test-tube plantlets of Chinese roses. According to the method, the flowering rate of diploids of test-tube plantlets can reach about 50%; and diploid flowers and pistil haploid flowers are flowered in a tower mode and exist for 20-35 days, and the flowering rate reaches about 30%.

The invention discloses a cultivating method of red-flesh apples. The cultivating method comprises the following steps in sequence: selecting the branches of apple trees with bud change; grafting the branches with bud change on Fuji apple trees to be used as male parents, wherein the branches with bud change are wooden, and the bast is red; collecting the pollen from the grafted branches; drying at 35 to 37 DEG C for standby; selecting the Fuji apple trees as female parents; removing stamens of the fame parents and remaining pistil at beginning-flower stage; and covering by a bag; pollinating the female parents by the prepared pistil at pistil mature stage; and cultivating the hybrid seeds in current season; and the seeds are flowered and fruited in the fourth years after the seeding, and is one month earlier than Fuji apples in mature stage. According to the cultivating method of the red-flesh apples, natural pistil is collected, and artificial pollination is implemented, so that the fertility rate is increased, natural pollens are adopted, and transgenosis molecules do not exist, so that the red-flesh apples are healthy and have no pollution; and according to the cultivating method, the germination rate and the branching rate are high, the fruit setting rate and the output are high, the yield stabilizing ability is high, and fruits are premature, high-quality and high-output.
