A Tree Physiologist's View of Growth Regulators

Changes of Lipid Metabolism and Their Effects on Cold Hardiness of Fapanese Pear during Flowering and Fruit Setting Periods.

“…Although overwintering floral buds may be quite resistant to Iow temperature damage, the results of our observation show that the flowers of pear gradually lose their cold hardiness with increasing differentiation, especially after full bloom. Abbott (1986) During flowering period, the changes in lipids and their fatty acid composition of the flowers were not significant. After full bloom stage, C16:0 in PI and DGDG , and C18:2 in PA, PC, PE and MGDG increased with time.…”

“…Flowering and fruit setting are associated with a great surge of physiological activities in plants (Abbott, 1986), during which the cold hardiness of flowers and fruitlets declines drastically (He, 1985). Lipid matrix and its fatty acid composition play fundamental roles in the physical and chemical properties of cell membranes which are the active sites for metabolic activities involving growth and the responses of plants to the environment (Kuiper, 1985).…”

Effect of the co-application of Promalin® at different bud phenological stages and notching at different distances on lateral branching of three sweet cherry cultivars (Prunus Avium L.) in central Chile

“…Important aspects to be considered at the moment of application are the phenological stage, the correct composition, concentration and timing of spray (Abbott, 1986).…”
