Özet:

 


Thirty year old
non-productive coffee (Coffea arabica
L.) trees were treated with three levels  of paclobutrazol (0 control, 0.5 g a.i and 1.0
g.a.i. PBZ /meter canopy span) using Cultar 1 and 2 months before rejuvenation
pruning and the effects on root carbohydrate, macronutrient contents and fine
root growth were assessed. Application of 1.0 g a.i. PBZ significantly
increased root starch content but did not affect the root sugar content. Plants
applied with PBZ 2 months prior to pruning had higher root P content compared
to those applied 1 month prior to pruning. 
Root N, P, K, Ca and Mg contents did not differ with time of PBZ
treatment.  The timing of PBZ application
had no significant effect on the root volume and dry weight but PBZ
concentration significantly affected root volume with plants applied with 0.5 g
a.i. PBZ per meter canopy span having  40% bigger fine roots volume relative to the
non-PBZ treated control.
