Inhibition of pear fruit ripening by mannose.
Softening of the flesh and the rise in ethylene evolution and respiration associated with ripening in pear (Pyrus communis L.) fruit was delayed when mannose was vacuum infiltrated into intact fruit. The extent of delay could be modified by altering the concentration or the volume of mannose applied to the fruit. Inhibition of ripening was associated with phosphorylation of mannose to mannose 6...
متن کاملTemperature-dependent Changes in the Polysomal Population of Senescent (Ripening) Pear Fruit.
A loss and recovery of polysomes coincident with the temperature-dependent interruption and resumption of pear fruit (Pyrus communis, L.) senescence establishes a close correlation between the presence of protein-synthesizing machinery and the progression of senescence and ripening.
متن کاملEffect of high temperature on calcium uptake by suspension-cultured pear fruit cells.
Uptake of Ca(2+) by suspension-cultured pear (Pyrus communis L. cv Passe Crassane) cells and protoplasts was significantly enhanced by exposure to 38 degrees C compared to 25 degrees C. The increased uptake was specific for Ca(2+) and was not due to cell wall binding. Tissues pretreated at 38 degrees C showed increased uptake even upon return to 25 degrees C. Treatment with carbonylcyanide m-ch...
متن کاملMetabolic and Other Responses of ‘Bartlett’ Pear Fruit and Suspension-cultured ‘Passe Crassane’ Pear Fruit Cells Held in 0.25% O2
‘Bartlett’ pears (Pyrus communis L.) that had been stored for either 2 or 8 weeks in air at 0C were placed under an atmosphere of 0.25% 0, (balance N2) at 20C for 4 days then returned to air. Control pears were kept in air at 20C. Suspension-cultured ‘Passe Crassane’ pear fruit cells in aging medium were treated similarly. During exposure of the fruit to 0.25% O2, loss of greenness and ethylene...
متن کاملseasonal changes in fruit growth and development in some asian pear (pyrus serotina rehd.) genotypes under tehran
growth in plants is defined as irreversible increase in volume and size. these changes are varied depending on stage of growth and physiological activity of the fruit tree. this research was conducted to determine the duration period of fruit growth and development and to come up with a mathematical model representing the relationship between fruit diameter, volume, and fruit fresh and dry weig...
