Influence of clomazone herbicide on postharvest quality of processing squash and pumpkin.

 

The influence of clomazone on fruit colour retention was evaluated over time in six processing squash and pumpkin cultivars that exhibited various degrees of clomazone sensitivity (marrow squash NK 530, field pumpkin Howden 691, Buttercup squash NK 773, Golden Delicious squash NK 792, Butternut squash Waltham 825 and Turk's Turban NK 822). Colour retention was monitored by total carotenoid content after curing. Relative levels of fatty acids and peroxidase (POD) and lipoxygenase (LOX) enzyme activities, associated with membrane and pigment integrity in higher plants, were assayed. Total carotenoid content of treated tissue varied, with Golden Delicious and Butternut squash significantly affected by herbicide treatment. Treatments of clomazone resulted in increased POD activity in Turk's Turban and Buttercup squash. No difference was observed for LOX activity in treated and control samples.
