Induction of Flowering in Asian Pear ( Pyrus spp. ) – A Review

摘要: Fruit production of Asian pear (Pyrus spp) trees is increased by the use plant growth regulators through bud breaking and flowering grown in subtopical to tropical areas. The effective are Hydrogen Cyanamide, Thioureas, KNO3, H2O2, GA3 GA4 GA 7. These (PGRs) may be used singly or combinations. In cell PGRs produce super oxide ion that alters protein structure phosphorylation which cause higher C:N ratio resulted heavy flowering. As dormant period shortened these bio-chemicals, earlier harvesting noticed treated plant. Now a day's Glutabion ® mixtures polysaccharides (W Uniformity Superplus) nutrients N-acetil cysteine, betains vitamins (Promvit) flower forming bio-chemicals for where HCN thiourea not available (Portugal). Growth retardant chemicals like SADH shoot bending increase ethylene synthesis damaged cells influence early formation Paclobutazol also promotes reduction spur.
