Abstract

Background and Objectives Grape is one of the fruit trees which require good management for economical production. Farmers often do not properly prune vine Grape. Grape cultivars show different responses to pruning severity. Perlette cultivar is among the new cultivars whose cultivation has recently been on the rise in Iran. The main objective of this research was to determine the effect of severity and the number of buds per shoot on yield and productivity coefficients of perlette Grape cultivar. Materials and Methods A factorial experiment based on randomized complete block design with three replications was conducted to evaluate the pruning effect on yield and yield components. Treatments included 42, 60 and 72 buds per vine and 6, 5 and 4 buds per cane during 2012 in Garaban agro industrial complex. Some different traits on fruit quantity and quality were measured. Results Results showed that the number of buds per vine and cane had a significant effect on the number of clusters, cluster weights, and yield and productivity coefficients. Vine yield was significantly different under various treatments: whereas the highest yield (about 12 kg/vine) was obtained by 60 buds/vine and long pruning with 6 buds/cane, the lowest yield (about 5. 6 kg/vine) was recorded in 42 buds/vine with 4 buds/ cane. The highest cluster weight (of about 250 g) was obtained in 60 buds/vine with 4 buds/ cane and the lowest cluster weight (182 g) was found in 72 buds/vine and 4 buds/ cane. The productivity coefficient was significantly different among the treatments at 1% statistical level. The highest productivity coefficient (0. 98) was found in the case with 42 buds/vine and 5 buds/ cane and the lowest was in 60 buds/vine with 4 buds/cane. Generally 60 buds/vine was recommended for this cultivar as a Mixed pruning with two replacing buds and a cane with 6 bearing buds. Discussion The number of clusters was increased by increasing the number of vine buds and cane buds. Cluster number is possibly dependent on the number of vine buds, which is one of the factors to increase the yield. The weight of cluster is affected by several factors such as productivity, the cultivar and so on. The highest yield was recorded in 60 buds/vine and 6 buds/cane. This phenomenon is related to a balance of vegetative and reproductive characters in this cultivar. Yield reduction occurred in 42 and 72 buds/vine. The decrease in the yield was due to a decrease in the weight of the clusters in 72 buds/vine. This is possibly due to the lack of adequate nutrition by the vine for cluster growth. Yield reduction was due to a decrease in the cluster production number in 42 buds/vine. Yield was increased with a decrease in pruning intensity. This phenomenon represents an increase in the number of buds on the fruiting canes. The long pruning with 6 buds/ cane and 60 buds/vine was superior to the others. This pruning severity was determined based on fruit yield and quality. Proper pruning leads to a balance between vegetative and reproductive growth and the quantitative and qualitative yields will be increased.
