The effects of three antitranspirants on yield and transpiration of potato cultivars

Abstract EN

Under greenhouse conditions.

antitranspirant chemicals wilt pruf, folicote and vapor guard.

reduced tran spiration rate of potato plants und er study by 38 to 50 % , Significant differences among chemical treatrncnt s as well as among potato cult ivars werc found .

Plant height.

dry mailer.

and yield .

were increased by antitranspirant treatments.

There are significant differences among chemical tre atments as well as among potato cultivars.

No signif icant differences among treatments for plant height was found but there were significant differences among cuitivars.

The effect of antitranspirant on number of leaves.

number of leaflets, and leaftlet size was insignificant.

Wilting degree was significantly reduced by antitranspirant chemicals , It appears that no economical profit was found by using two applications of chemicals compared to one application ,
