Amygdalin contents of the seeds, endocarps, and mesocarps from three peach cultivars (i.e., Stone Peach, Hikawa Hakuho, and Bakhyang) were measured at three stages of fruit development (stone-hardening, fruit enlargement, and ripening). The peach samples were dried and defatted with a Soxhlet apparatus, reflux extracted with methanol, and analyzed using reverse phase high-performance liquid chr...

The present study was aimed to determine the effect of foliar application of micronutrients (Fe, B and Zn) on the quality of mango (Mangifera indica L.) cv. Dusehri plants. For this purpose, 21 healthy, full bearing and mature (20-25 years old) trees were subjected to foliar application of different combinations of FeSO4, H3BO3 and ZnSO4 before flowering and at full bloom stage. Results reveale...

Mangoes account for approximately half of all tropical fruits produced worldwide. India is the largest mango producer, accounting for about half of the global mango production. But, less than five per cent of the produced mangoes are processed and mango pulp is the main export product both in terms of volume and value. Contract system is the major marketing system in the supply of mangoes becau...

plum pox virus (ppv), the causal agent of sharka disease, belongs to the genus potyvirus in the family potyviridae and has been reported from some regions of iran. surveys were conducted to determine the incidence of the virus in khorasan razavi province in 2010 and 2011 and 553 samples of stone fruit trees were collected and tested by das-elisa. in this method 12 samples were infected with ppv...

BACKGROUND AND AIMS There is good evidence for deciduous trees that competition for carbohydrates from shoot growth accentuates early fruit abscission and reduces yield but the effect for evergreen trees is not well defined. Here, whole-tree tip-pruning at anthesis is used to examine the effect of post-pruning shoot development on fruit abscission in the evergreen subtropical tree macadamia (Ma...

We studied the influence of branch autonomy on the growth of reproductive and vegetative organs by establishing different patterns of fruit distribution within and between large branch units (scaffolds) in mature peach trees (Prunus persica (L.) Batsch cv. 'Elegant Lady'). Different patterns of fruit distribution were established by defruiting either whole scaffolds (uneven fruit distribution b...

Sixteen mature Valencia orange trees on rough lemon rootstock were selected on the basis of approximately equal, naturally occurring populations of Tylenchulus semipenetrans in soil. In March, fruit 1 cm in diameter or less were removed from eight of the trees, which were kept free of fruit for 15 months. In July, 4 months after fruit removal, fibrous root (<2 mm d) mass density of defruited tr...
