COMMUNITY STUDIES 



1. Visit several orchards and determine whether any provisions have 

 been made for cross-polHnation between varieties. 



2. Secure data on the date and length of the blooming period of 

 several varieties of all tree fruits in the community. 



3. From the data obtained from Study 2, determine what varieties 

 would be suitable for cross-pollination purposes as far as the over- 

 lapping of their blooming periods is concerned. 



4. Determine whether orchards consisting of several varieties "set'' 

 a higher percentage of their blossoms than orchards of one variety. 



5. Which varieties of the different tree fruits appear to '^sef the 

 highest percentage of blossom, when planted in solid blocks? 



6. Is the ^^set" of fruit as heavy in seasons when the weather is cold, 

 rainy, and windy during blossoming time as when it is warm, quiet, 

 and sunny? 



7. Determine where beehives should be located in the orchard for 

 cross-pollination purposes. 



8. Remove the petals from a few apple blossoms before the petals 

 open, and determine whether bees visit such blossoms when the showy 

 attractive petals have been removed. 



9. Place some paper bags over several blossoms of the different tree 

 fruits just before the petals open, and remove the bags after the petals 

 have fallen. Determine which varieties ^^set" fruit under the bags. 



10. Collect and ripen pollen of several varieties of apples, emasculate 

 a few blossoms of each variety, and make several different cross-pollina- 

 tions. Determine later which crosses have resulted in the best set of fruit. 



11. Collect blossoms of several different kinds of fruit. Study them 

 carefully, make drawings, and label the different parts. 



12. After the "June drop" determine whether there are more or less 

 good seeds in the apples which have fallen compared to those still 

 remaining on the tree. * 



13. Visit several orchards at blossoming time and determine the 

 different insects that are visiting the blossoms. 



14. What percentage of the blossoms "set" fruit in : (a) a well-cared- 

 for, vigorous orchard, and {h) a poorly cared-for weak one?
