growth in plants is defined as irreversible increase in volume and size. these changes are varied depending on stage of growth and physiological activity of the fruit tree. this research was conducted to determine the duration period of fruit growth and development and to come up with a mathematical model representing the relationship between fruit diameter, volume, and fruit fresh and dry weig...

high-density planting system is one of the effective methods for improving production and profitability of tree orchards. in this research, the effects of four planting densities (1904, 2666, 3137 and 4800 tree/ha) on annual shoot growth, tree yield, physicochemical properties of fruit and leaf mineral contents of apple (malus domestica borkh cv ‘granny smith’treegrafted on m26 clonal rootstock...

this study was conducted with the main purpose of investigating genetic variation among 13 selected sweetcherry (prunus avium cv. siah mashhad) genotypes, i.e., the most important iranian sweet cherry cultivars based on their pomological, morphological, and phonological characteristics. the experiment was laid out in a randomized complete block design with three replications at khorasan-e-razav...

selection and introduction of superior genotypes from native populations is one of the most common improving methods for fruit trees in the world. iran as a very important origin of apricot has a huge diversity of varieties, so a rich collection of local and imported genotypes of apricot was induced in sahand horticultural research station from 1971. nasiri 90 and other four superior varieties ...

quince fruit has many benefits to human health and is an excellent source of pectin for jellies and jam industry. the objective of the present research was to study fruit physio-chemical attributes of some quince genotypes at harvest and their changes during cold storage. the fruit of 15 genotypes were harvested at optimum maturity and stored for 0, 30, 60, 90 and 120 days in cold storage and s...

five levels of salicylic acid (sa), (0, 2, 4, 6 & 8 mm) were sprayed on strawberry cv. comarosa fruit bearing plants in a hydroponic culture. growth, yield & fruit quality attributes were assessed. vegetative characteristics (crown number, root & shoot weight), reproductive traits (yield, fruit number as well as shape), fruit quality, macro elements (ca, mg, k & p), dry weight & ash were evalua...

the effect of shoot pruning (2, 3 and 4 branches per plant) and fruit position selection (on main branch vs on main and lateral branches) on yield and qualitative characteristics of two greenhouse grown pepper (capsicum annuum l.) cultivars (torkal and paramo) was studied through a factorial experiment arranged in a completely randomized block design, of three replications. results indicated th...

to study yield and its components by the method of multivariate analysis, 25 genotypes of melon were sown on the basis of square lattice design of 2 replications in zahak agricultural research station. analysis of variance showed that there were significant differences among genotypes in some such characters as: fruit weight, width, and seed weight and yield. simple correlation coefficients sho...
