4 MODERN STRAWBERRY GROWING 



can, or cannot, withstand the long cold of 

 the North or the frosts (both early and 

 late), or they cannot stand the exces- 

 sive heat or sunlight of the South or mid- 

 South. 



This adaptability is not surprising, since 

 we recognize such things as "plant associa- 

 tions" or "societies" in which a certain 

 group of plants live together under certain 

 conditions of climate, moisture and other 

 factors. And it has been found that by selec- 

 tion and breeding, or both, either natural 

 or artificial, it is possible to change the 

 requirements of a plant so that it is more 

 adapted to a condition of cold weather than 

 it is to hot weather, or vice versa; or it has 

 changed its characteristic choice for great 

 moisture to a liking for drier conditions; or 

 in some other way it has been so modified 

 that it can and does live under different 

 environment or surroundings than it re- 

 quired in earlier stages of its develop- 

 ment. 



Applying this idea to strawberry plants 

 originating in the South: They can be 

 brought North, and in a few years their 

 descendants will be, or can be made to be.
