Comparison Test of Training Systems and Its Influence on Yield and Fruit Quality of G.Delicious on Clonal Rootstocks
Journal Title: Scientia Agriculturae - Year 2016, Vol 14, Issue 3
Abstract
In order to determine the best form of training on Golden Delicious variety grafted on dwarf apple rootstocks, five different forms of training were examined to increase productivity and quality of apple fruits in different regions of Iran. The experiment was conducted in randomized blocks design arranged in split plots with three replications at two phases. The first factor consists of four different apple rootstocks include: B.9, M.26, M.9 and MM.106 and the second factor consisted of five training forms include: Spindle bush, Slender spindle, Solen, Modified leader and Palmet. During 2002 and 2003, rootstocks were planted. During the experiment, vegetative characteristics and fruits characteristics of apple trees such as tree height, vegetative shoots growth, trunk diameter, expand the tree canopy, fruit size, fruit weight, fruit hardiness, fruit aroma and flavor, fruit soluble solid substance (TSS), titrable acidity (TA), sugar, yield and cumulative yield of trees were measured. The obtained results indicated that the effect of year, rootstocks and training forms as well as their interaction was significant on all vegetative traits at 1 %. Although, the effect of rootstocks was significant on fruit yield, fruit size, fruit weight and fruit hardiness at 1 %. But was not significant on qualitative traits in some regions. The effect of training forms was significant on most of fruit characteristics. The MM.106 rootstocks produced the highest yield and cumulative yield compared to other rootstocks. Palmet and Solon training forms in different regions caused less vegetative growth and yield compared with other training forms. In addition, slender spindle training form produced the highest fruit yield. In general, the lowest fruit yield was related to Palmet and Solen training forms practiced on M.26 and B.9 rootstocks and the highest fruit yield was related to slender spindle and Modified leader practiced on MM.106 rootstocks.
