546 FUNDAMENTALS OF FRUIT PRODUCTION 



cross pollination in established self unfruitful or inter-unfruitful orchards. 

 Insects, particularly the honey bee, are the most effective pollinating 

 agents in the deciduous fruit plantation. There should be ample provi- 

 sion for pollen transfer, even in orchards of self fruitful varieties. The 

 fruit setting habits and polHnation requirements of different deciduous 

 fruits are discussed.
