A Study of the Impact of Pruning on the Growth and Vigority of the Hand-Planted-Haloxylon Trees in Kerman, Iran

Abstract:
Pruning and reaping different quantities (P1-5) of air biomass of the haloxylon trees were studied in two different haloxylon planted areas from the viewpoint of vigority. It was done within the format of the design of fully random blocks with five treatments (pruning from the 10 cm over the collar, pruning 150 cm of the top branches, pruning 100 cm of the top branches, pruning 50 cm of the top branches and control) and four repetitions as possible ways to remove wilting state, dying status and revive the vigor condition of hand-planted shrubs. The index of VI = H (CD) a-1 was accepted out of many quantitative indexes as the symbol of vigority (quality) which could show the vigorous quality in the form of a quantitative quantity after testing in hand-planted shrubs of Kerman Province. The average of this index in each of the three germinating conditions (vigorous, wilting and dying) was 1370, 780 and 280, respectively. The statistical studies showed that there was a significant difference among its quantities in different degrees of vigority. In other words, the quantities of this index, in addition to the size of growth showed its quality (the vigority degree) as well. The analysis of the data in LSD method during a 5-year research showed that the impact of P1 and P2 on the growth of trees and also VI in both regions were significant. The results showed that the intensive prunings are able to increase the growth of wilting haloxylon and rejuvenate their vigority and freshness.
