Read More Background and ObjectivesGrape is one of the fruit trees that need to well management to produce economical production. Farmers often do not properly prune vine grape. Grape cultivars show different response to pruning severity. Perlette cultivar cultivation is increased recently. The main objective of this research was to determine the severity and number of buds per shoot on yield and productivity coefficient of perlette grape cultivar. Materials and methodsA factorial experiment based on randomized complete block design with three replications was conducted with three charges levels 42, 60 and 72 and three buds number per shoot include (6-2 buds), (5-2) and (4- 2) during 2012 in Garaban agro industrial complex. Some different traits on flower and fruit quantity and quality were measured. ResultsResults of mean comparison showed that Charge, number of buds per shoot and their interaction effects were significant on number of cluster, cluster weight, yield and productivity coefficient. The interaction effect between charge and the number of buds on the yield per plant showed that the highest yield (about 12 kg) was obtained by charge 60 and long pruning with 6 buds and the lowest yield (about 5.6 kg) was in charge 42 with 4 buds on the branches. The highest cluster weight of about 250 grams was obtained in charge 60 with 4 buds on the branches and the lowest cluster weight (182 g) found in charged 72 and 4 buds on the branches. The interaction effect of charge and the number of buds per shoot was significant on productivity coefficient at 1%. The highest productivity coefficient (0.9833) was found in the charge 42 and 5 buds per shoots and the lowest was in charge 60 with 4 buds per shoots. Generally 60 charge was recommended for this cultivar as mixed pruning with two replacing buds and a shoot with 6 bearing buds.DiscussionIncreasing the number of clusters possibly depend on increasing the charge level, which is one of the yield increasing factors. Berries weight loss and berries abscission lead to cluster weight reduction and yield was affected. Thus, the high charge of 72 buds per plant caused yield loss due to small clusters. This phenomenon is possibly due to lack of adequate nutrition by the vine for cluster growth. Yield reduction in 42 charges was due to a reduction in the cluster production number. Yield was increased with a decrease in pruning intensity, which represents an increase in the number of buds on the fruiting branches. The long pruning with 6 buds per cane and 60 charges was superior to the others. This pruning severity was determined based on fruit yield and quality. Proper pruning lead to balance on vegetative and reproductive growth and quantitative and qualitative yield will be increase.

Read More Abstract Background and Objectives Olive (Olea europaea L.) belongs to Oleaceae family. Olive fruit has been used for oil and table olive. Olive is one of the most important fruit trees around the world. Iran is one of the regions of the world with different wild olive genotypes distributed in different provinces. Olive genotypes are important genetic resources for Iran. These genotypes can be selected as promising genotypes and used in breeding programs. The objective of this study was to evaluate adaptability of 8 olive genotypes from Gorgan and Taroum. Materials and Methods This experiment was conducted to evaluate adaptation ability of 8 olive genotypes in Tarrom olive research station during 2007- 2011. Trees were planted under a complete randomized block design with a 6 × 6 distance. Vegetative and reproductive characters of olive trees were measured. The collected data were analyzed with MSTATC and the means were compared with Duncan's multiple test. Results Vegetative results showed that tree height, wide, shoot season growth and trunk cross sectional areas were significantly different at 1% between olive genotypes in Tarrom olive station. Inflorescence number per shoot, flower number per inflorescence, perfect flower percent, and final fruit set were significantly different at 1% statistical level. Fruit weight was significant between olive genotypes and it varied between 2.3 and 9.8g. G4 genotype had the biggest fruit and flesh weight. Fruit yields were significant between genotypes so that T2 and B1 had the highest and lowest yields respectively. The oil percent in dry matter was significantly different between genotypes. All genotypes had higher than 40% oil in dry matter. The highest oil percentage (52%) was recorded in G4 genotype. Generally, G4 olive genotype could be a promising genotype due to the large fruit (more than 9 grams), relatively high yield (about one ton) and high oil content (more than 52% of the dry matter). Discussion Wild olive genotypes are very important gene pole for any purposes in each county. Iran has different wild olive genotypes in different regions like Golestan, Gilan, Kerman, Kermanshah, Ilam and so on. Identification and evaluation of adaptability of local olive genotypes are very important for new olive cultivar selection and breeding programs. As mentioned above, the evaluated olive genotypes show different responses in Taroum olive research station. Different vegetative and reproductive characteristics were recorded on evaluated olive genotypes. Generally, results showed that G4 olive genotype was superior based on fruit traits, oil and yield.
