How to carry out Scientific Hybridization in Magnolia

The scientific hybridization methods of Clivia: ① selecting hybrid parents. Before artificial pollination, parents should be selected according to needs to form hybrid combinations. Selecting male parents with excellent traits can influence the traits of female parents and achieve the purpose of complementing each other.

(2) Artificial pollination process. First of all, when a single flower begins to bloom, stamen anther is not dehiscent before, should use tweezers to pull out stamen completely as soon as possible. If it is not only a pot of flowers, to stamen after the entire inflorescence with a transparent paper bag cover, in case of natural hybridization. Second, select and collect pollen grains. Pollen should be taken with tweezers to hold the filaments, after picking the pollen shake off in a glass culture dish covered, put to 0℃-4℃ dry dark shade preservation, generally can survive for about a week. The best time for pollination is the morning of the second day after the pistil ovary egg cell and stigma mature, about the second day after the petals open. At this time, use a magnifying glass to see that there is mucus secretion at the top of the pistil stigma. Dip the collected male pollen grains with a new writing brush and gently smear them on the pistil stigma. Repeat once more on the second day to fertilize. After pollination of each flower, a label should be hung indicating the name of the parent, the date of pollination and the number of times, so as to facilitate variety selection.
