Abstract:
The change of the content of soluble sugar,starch,the nitrogen in apical buds and leaves of short branches and long branches of ‘Gala’ apple with different branch bending angles were studied.The results showed that the content of soluble sugar and starch was raised with the increasing of branch angles.The difference of content of starch in apical buds of long branch and soluble sugar in leaves of short branch between the branch angle of 90° and 110° was not significant,the other was obvious.With the increasing of branch angles,the content of nitrogen was declined,the different was not significant,the content of nitrogen in apical buds was declined with time,but the content of nitrogen in apical buds of long branches was raised in September.The content of nitrogen in leaves was showed an upward trend in its opening stages,the content was declined since peaked during June 15 to 25.The C/N was raised with the increasing of branch angles,but the different was not significant between the branch angle of 90° and 110°.
