STUDIES ON SOME MUL TIUSES OF Annona. senegalensis AS POLLINATOR, ROOTSTOCK AND POLLINATION TREATMENTS FOR IMPROVING FRUIT SET PERCENTAGES AND FRUIT QUALITIES

The studies were conducted during the two successive seasons of 2001 and
2002. The studies aimed to focus on A senegalensis as multiuses fruit tree which was
not established enough in Egypt. Some of the uses are investigated in the present
study (1) The use as pollinator, (2): The availability of non edible fruits to be used in
food processing and trial to solve processing problems using cross hand pollination of
Annona atemoya, Asquamosa and selected Squamosa male parents. Pollination is
also used for improving fruit qualities to meet the future needs of processing. (3): The
use as rootstock for different cherimoya (Annona) species, (4): The availability of
seeds to produce sufficient rootstocks and some and the best container, (5): fresh
consumption. The data indicated the effeciency of using A senegalensis as pollinator
for other annona in controlled pollination increasing fruit weight, pulp and TSS
percentage while decreasing seed number and could be used also as complementary
pollinator during lack of pollen. The primery studies encourage the processing to of
fruits and trial to improve qualities for processing by pollination of other annonas
increased pulp weight. The tree had superior survivability under different
environments and is excellent rootstock to known and selected annonas, the growing
in black bags is better than plates and pots to raise suitable rootstocks. The annona
senega/inses is a fighter tree under different conditions and multiuses easy
propagated tolerant tropical fruit tree recommended to be more established. The
disadvantage is the high seed number could be overcome buy pollinating with good
variety or use the seeds for medical or natural pesticide uses
