FUNDAMENTALS OF FRUIT PRODUCTION 



Table 4 indicates the amounts of water found in various parts of the 

 chestnut and walnut at different seasons and Table 5 shows the mois- 

 ture content of bearing, non-bearing and barren spurs of the apple at 

 various periods. All spurs have a maximum water content during or 

 directly after the time of blossoming, but blossoming spurs contain 

 much more water than spurs in the off year and these more than 

 barren spurs.

 Chestnut and Walnut^ 



Besides being a plant constituent, water is a plant nutrient and as such 

 is indispensible for the manufacture of plant material, particularly in the 

 photosynthetic production of carbohydrates. Finally, water is the 

 medium in which all the nutrients essential to green plants, except carbon, 

 occur in solution. >
