A significant increase in L/D ratio was attained with both GibberellinsA₄A₇ +6-benzyladenine
containing compounds as compared to the Untreated Control in both experiments. In the Pittstown
Fruit Farm trial both Typy[TM]and Promalin^®significantly increased average fruit weight.

Typy[TM]performed as expected significantly increasing the L/D ratio on two strains of Red Delicious at
two locations and significantly increased average fruit weight of Red Chief^®

The test was considered to be definitive.
