Evaluation effect early fruit let harvest on the growth indices in almond (P. amygdalus)

ABSTRACT: Tress almond has a best adaptability to arid and stony region. Seedling grafted product a fruit in first year after cultivation, but this fruit harvested by farmer for uses. This operation has a suitable because a tree has a time for best growth and development. This work was studied in almond selections and established at 3 m x 5 m (667 trees/ha) in Ilam province. The evaluated affect of fruit let (unripe fruit) harvest on branches growth, number branches (spurs), length and width leafs, trees canopy, bloom density, fruit set. Flower quality and later fruit quality of fruit trees have been shown to be dependent on the type of fruiting branch. The analysis of variance showed significant differences among genotypes for these tree traits. Flowers morphology may also affect in harvested branches. Although, morphological condition will be related to genotypes and environment condition. Showed a highly correlated with bloom and fruit density. Fruit density was positively correlated with bloom and spur density. Too was significant correlation between fruit let harvested with number branches, tree canopy, bloom density and fruit set but not significant with length and width leaf. At this study was significant the yield result. The results showed a large variability of bloom density among the genotypes traits.
