THE EXPERIMENTAL RESULT WITH HIGHBUSH BLUEBERRY UNDER VINYL HOUSE

In this experiment, the plant of Weymouth, Earliblue, Spartan and Collins were grown in pots.
The plants were prepared in early March under the vinyl house and a small honey clony was provided during the time of flowering.
Openleaf and flowering time advanced earlier about 10 days due to relatively high temperature under the vinyl house.
The first harvest was 17 days earlier than plants set in the open field.
Fruit set’s percentage by honey bees caged under the vinyl house was higher than by open pollination in the open field.
Honey bees that bring about pollination under the vinyl house have resulted in increaseing the number of seeds above 0.71mm diameter per fruit.
A berry weights of the plants that moved from the vinyl house to the open field after falling of blossoms were much larger than the plants that grew throughout experiment in the open house.
However this experiment showed no difference in fruit quality.
Leaves of the plants grown throughout experiment under the vinyl house showed tendency to form shade leaves.
