generally, fruit trees should produce sufficient yield annually through their economic life. fruit trees usually produce flowers over their ability of productivity. if all of the flowers are converted to fruit, the tree will be weak and poor smaller fruit will be produced and it may cause alternate bearing. thus some flowers must be removed by hand, mechanically or chemically. in this study, 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...

Endocarp lignifi cation is important fruit growth phenophase since aft er its completion fruit starts with oil accumulation. Th e information about duration of endocarp lignifi cation is important for timing of management practices, irrigation and pest control in oil cultivars, and fruit thinning in table cultivars to obtain uniform fruit weight and size. In this study, fruit length, width and ...

The present study was conducted on five ber (Ziziphus mauritiana Lamk) cultivars (Komethry, Pakstany, Um-sulaem, Toffahy and Peyuan) grown in Saudi Arabia during 2005 and 2006 seasons. The aim of the present study was to investigate fruit properties (fruit weight, length, diameter, shape, specific gravity, seed weight, pulp percentage, total soluble solids (TSS), acidity percentage, TSS/acid, v...

Prolonging the marketing period of peach fruits in Egypt through introducing new cultivars, breaking dormancy early or delaying maturity of some cultivars by safe compounds would increase the growers' profits. This study was conducted during two successive seasons 2005 and 2006 by using "Desert Red" peach cultivar (Prunus persica L.) grafted on Nemaguard rootstock. Trees were grown at El-Noubar...

abstract evaluation of pomological characteristics can be useful in selection of best cultivars for commercial purposes. during this project, seven cultivars of sweet cherry including five cultivars from hungary (‘stella’, ‘sunburst’, ‘germesdorf’, ‘summit’ and ‘subima’) and two control cultivars (‘cillage blamarka’ and ‘siahmashad’) were studied by completely rondomized blocks design with thre...

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...

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...

Heterogeneity in fruit quality (size and taste) is a major problem in pineapple production chains. The possibilities were investigated of reducing the heterogeneity in pineapple in the field by pruning slips on selected plants, in order to promote the fruit growth on these plants. Slips are side shoots that develop just below the pineapple fruit during fruit development. Two on-farm experiments...

this investigation was carried out in a commercial orchard in ashtian city, markazi province. the effect of n-phenyl-phthalamic acid and nutrition on fruit quantity and quality of plum cv. maragheh was studied with the aim of increasing yield. the n-phenyl-phthalamic treatments (concentrations, 0, 500 and 1000 mg/l) were performed at full bloom (80 % flowering) on 29 march. also, nutrition was ...
