Research Topics : Physiological responses of harvested horticultural commodities to the abiotic stresses of wounding, chilling temperatures, and altered gaseous atmospheres. Understanding the physiological basis of stress responses and devising treatments to minimize chilling injury and reduce wound-induced browning of fresh-cut lettuce are currently our major areas of research. Plants respond to stresses in a hierachical order such that the response to one stress can supplant the response to another stress. The response to heat-shock and associated stresses supercedes the response from wounding. The resultant synthesis of heat-shock proteins monopolize the protein synthetic capacity of the cell and thereby prevents the synthesis of wound related enzymes that among other things, result in tissue browning.

Commodities : Lettuce, cucumber and rice sprouts, tomato fruit.

Instrumentation : CA chambers and control system, controlled environment chambers, fluorometer, GC’s for ethylene determination, HPLC, incubators, Instron firmness testers, IRGA CO 2 analyzer, Minolta chromameter, paramagnetic O 2 analyzer, refractometers, SDS gel units, slab mini agarose gel units, UV/Vis spectrophotometer,
