abstract in order to provide optimal yield and quality of tomato fruit (lycopersicon esculentum mill. cv. beril), different growing media for soilless culture of tomato plants were studied. seedling of tomato (lycopersicon esculentum mill, cv. beril ) were cultivated in perlite, mixture of perlite with nh4-zeolite and with raw zeolite (z:p ratio 10v:90v) and fed by two nutrient sources: a) comp...

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...

orchard intensification is motivated by the desire to produce fruit early in the life of the orchard to rapidly recover establishment costs. intensification is possible using dwarfing rootstocks that control tree size, induce early cropping and produce large quantities of fruit compared to the amount of wood produced. therefore, this study attempts to compare some yield and fruit properties of ...

Municipal solid waste compost (MSWC) and/or fertigation used in greenhouse pepper (Capsicum annuum L.) cultivation with five different substrates with soil (S) and/or MSWC mixtures (0-5-10-20-40%) used with or without fertigation. Plants growth increased in 10-20% MSWC and fertigation enhanced mainly the plant height. Fruit number increased in S : MSWC 80 : 20 without fertilizer. Plant biomass ...

Limited-cluster production systems may be a useful strategy to increase crop production and profitability for the greenhouse tomato (Lycopersicon esculentum Mill). In this study, using an ebb-and-flood hydroponics system, we modified plant architecture and spacing and determined the effects on fruit yield and harvest index at two light levels. Single-cluster plants pruned to allow two leaves ab...

Pear (Pyrus spp) is an important fruit crop, grown in all temperate regions of the world, with global production ranked after grape and apples among deciduous tree crops. A high-density linkage map is a valuable tool for fine mapping quantitative trait loci (QTL) and map-based gene cloning. In this study, we firstly constructed a high-density linkage map of pear using SNPs integrated with SSRs,...

the effect of the organic, integrated and conventional methods of kiwifruit cv. 'hayward' production on the fruit quality at its harvest time was investigated. such traits as fruit size, firmness, total soluble solids (tss), titratable acidity (ta), total chlorophyll, total carotenoids, vitamin c, total phenol, flavonoid compounds (catechin, quercetin 3-glucoside and chlorogenic acid)...

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...

grading of agricultural products has always been a subject of research by scientists. one of the criteria to be chosen for grading of fruits is the fruit's level of ripeness. different methods have been employed to assess the status of fruit ripeness some of which are destructive and others are not so. in this research, a noninvasive capacitive method was used to estimate the ripeness leve...
