The invention relates to the field of cross breeding of plants and particularly relates to an interspecific hybrid embryo rescuing and seedling forming method of sweet cherries in southern China and Chinese cherries. The method combines advantages of European sweet cherries and the Chinese cherries, and takes the 'European sweet cherries' as a female parent and the 'Chinese cherries' as a male parent to carry out interspecific distant hybridization. Aiming at the abortion problem of a distant hybrid embryo, the hybrid embryo is subjected to embryo rescuing. A proper sampling period of the embryo rescuing of each hybrid combination, concentrations and ratios of respective exogenous growth regulators for hybrid young embryo germination, subculture propagation and rooting culture, and a proper acclimatization and transplanting method are determined. By applying an interspecific hybrid embryo rescuing system of the sweet cherries in southern China and the Chinese cherries, which is established by the technology, the embryo germination rate reaches 80.00 percent, the multiplication coefficient of subculture hybridized new shoots reaches 5.0, the rooting rate of rooting culture is 90.91percent, the growth vigor of embryo culture seedlings is good and the seedlings grow robustly and have green leaves, and the acclimatization and transplanting survival rate reaches 77.27 percent.

The invention discloses a cherry seedling cultivation method. Newly germinating green plump buds without leaf expansion are cut from a cherry plant and serve as explants for plant tissue culture to obtain non-toxic cherry seedlings with good varieties. The cherry seedling cultivation method has the advantage that an improved 1 / 2 MS culture medium is prepared and serves as a rootless seedling rooting culture medium. All components in the 1 / 2 MS culture medium have coupling functions, the activity of polyphenol oxidase (PPO) can be effectively improved, the condensation reaction rate of catalytic IAA (indoleacetic acid) and phenolic substances is increased, production of 'IAA-phenolic acid compounds' is increased, formation of adventitious roots is promoted, grown roots are white and robust,and water and mineral substance absorption efficiency is high. Finally, the obtained cherry seedlings are virus-free, and good varieties of female parents are effectively retained.

The invention discloses a control technology applied in the cherry maturation stage. The control technology applied in the cherry maturation stage comprises the steps that a sunshade net is arranged above Summit cherry trees in a covering mode after fruit setting; water is sprayed to the cherry trees at noon every day, so that the cooling function is achieved, wherein the spraying frequency is that spraying is conducted once per half hour and spraying is conducted four times every day, and the spraying amount meets the requirement that each whole cherry tree is wet; after 80vt% trichlorfon is diluted 1000 times, the diluted trichlorfon is sprayed to the root portion of each cherry tree, so that drosophila eggs are prevented from entering cherry fruits, and the problem that drosophila larvae appear in the cherry fruits is solved, wherein the problem that drosophila larvae appear in the cherry fruits bothers farmers. By the adoption of the control technology applied in the cherry maturation stage, the cherry maturation time can be postponed until over 25 days later.
