Ethylene production by auxin-deprived, suspension-cultured pear fruit cells in response to auxins, stress, or precursor.

Auxin-deprived, mannitol-supplemented, suspension-cultured pear (Pyrus communis L. Passe Crassane) fruit cells produce large quantities (20-40 nanoliters ethylene per 10(6) cells per hour) of ethylene in response to auxins, CuCl(2) or 1-amino-cyclopropane-1-carboxylic acid (ACC). Maximum rates of production are achieved about 12 hours after the addition of optimal amounts of indoleacetic acid (...

The effect of virulence on cultivation of Theileria annulata strains in lymphoid cells which have been cultured in suspension

Metabolic 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...

Non-destructive Measurement of Calcium and Potassium in Apple and Pear Using Handheld X-ray Fluorescence

Calcium and potassium are essential for cell signaling, ion homeostasis and cell wall strength in plants. Unlike nutrients such as nitrogen and potassium, calcium is immobile in plants. Localized calcium deficiencies result in agricultural losses; particularly for fleshy horticultural crops in which elemental imbalances in fruit contribute to the development of physiological disorders such as b...
