The effects of pre-sowing magnetic treatments on the growth and yield of tomatoes (cv. Vyta), cultivated late in the season, were studied under field conditions. Tomato seeds were exposed either to a 120 mT dynamic magnetic field (induced by an experimental electromagnet) for 10 min or to a 80 mT field for 5 min. Non-treated seeds were used as controls. Plants were grown in experimental plots (...

abstract considering to importance and high genetic diversity of pear (pyrus communis l.) in iran, a study was conducted on the effect of genotype on fruit physicochemical properties and qualitative characteristics of six mature european pear genotypes in teheran, iran environmental conditions. in this study some physicochemical fruit properties and qualitative characteristics such as: fruit le...

carbohydrate flow between vegetative and reproductive parts of trees is one of the determining factors of yield and fruit quality. therefore, it varies during different times of growth season. the aim of this study was to investigate the carbohydrate content variation during growth season between leaf and fruit of nectarine. so, eight nectarine trees cv. red gold selected randomly in the orchar...

abstract to study the effects of xenia and methaxenia on the pistachio nut, 4 male genotypes from among all male genotypes provided by rafsanjan pistachio research institute were selected. the flowering period of the chosen genotypes was the same as 3 female cultivars of kalleghoochi, ohadi, and ahmadaghaii. by using split plot in the form of completely randomized blocks design, we conducted va...

Organic vegetable production has specific research and innovation requirements which are not shared by other parts of the food and farming sector. A pot experiment was conducted to investigate the interactive effects of few permitted organic inputs such as arbuscular mycorrhizal fungi, biochar, and different ratios of peat:worm casting on tomato (Solanum lycopersicum L.) growth, mycorrhizal dep...

in this investigation some chemical and morphological properties of dog rose fruit in 10 regions of north iran were measured. results showed significant difference between traits in studied regions. beta-carotene ranged between 0.05 – 0.323 (mg/g fw). total soluble carbohydrate varied from 5.9 – 23.3%. the highest content of total anthocyanin 23.7 and the lowest was 7.71(mg/l cyanidin-3-glucosi...

The objective of this study was to investigate the effect of pruning in different developmental stages on growth, development, seed yield and active substances of medicinal pumpkin (these active substances are uses for remedy the Benign Prostatic Hyperplasia (BPH)). The experiment was performed in a RCB design. Five pruning treatments in different developmental stages (no pruning, after 3-5 nod...

SUMMARY Avocado seed are usually considered as waste or as a source of seedlings suitable for use as rootstocks. This paper emphasizes the changing composition of avocado seed and how as a storage organ certain constituents are translocated from it to other portions of the fruit or tree. The fresh and dry weight and some of the inorganic constituents were determined in the dry matter of the see...
