Abstract Plants need adequate nutrients in all stages of growth, which should be available in the growing medium. This study was performed to examine the effect of different substrates on nutrient uptake and quantitative and qualitative yield of greenhouse strawberry. The experiment was carried out in the research greenhouse of Jihad-e- Daneshghahi, West Azarbaijan, using a completely randomiz...
In order to investigate the effect of pruning and potassium nutrition on pumpkin grain yield and quality, a factorial experiment based on complete block design with four replications was carried out in nooshar village of ardabil province, Ardabil, Iran, in 2007. Experimental factors include potassium nutrition in three level (0, 75 and 150 kg/ha from potassium sulfate) and stem pruning (without...
In order to study of marmarine spraying effects on some physiological and antioxidant parameteres of tomato Lycopersicon esculentum cv. Teena, an experiment was conducted in complete randomized block design with 3 replications in field. Experiment treatments were three ascophyllum extract concentrations as (0, 1.5 and 3 ml/L) and four spraying stages of plant growth including (exactly after tra...
The effects of salinity and supplied calcium chloride on growth and leaf ions concentration of tomato (Lycopersicon esculentum L.) were investigated in Gorgan, Iran. A factorial experiment was conducted based on RCBD with four NaCl levels (0, 50, 100, and 150 mM) and four CaCl2 levels (0, 100, 200 and 300 mg L-1). Data of growth, yield and leaf’s Ca, K, and Na content were subjected to analyze ...
Self-incompatibility has been studied by using controlled pollination, pollen tube growth and PCR methods in the Iranian almond ‘Mamaei.’. Pollen tube growth and fruit set following self and cross-pollination treatments were evaluated. The percentage of initial and final fruit set was determined for each treatment at 30 and 60 days after controlled pollination. Pollen germination and pollen ...
This experiment was conducted to determine the effect of salinity and nitrogen on growth and yield of tomato and concentration and total uptake of some nutrients in different parts of plant in hydroponics culture. Nitrogen (N) was used at 0, 1.5 and 3% levels as NH4Cl and NH4H2PO4 and salinity consisted of 0, 30 and 60 mM as NaCl and CaCl2 (2:1 w/w). A completely randomized design experiment wa...
Key mechanisms controlling fruit weight and shape at the levels of meristem, ovary or very young fruit have already been identified using natural tomato diversity. We reasoned that new developmental modules prominent at later stages of fruit growth could be discovered by using new genetic and phenotypic diversity generated by saturated mutagenesis. Twelve fruit weight and tissue morphology muta...
Background and purpose: The majority of patients with cancers of the digestive system admit themselves to the health care systems in the final stages of the disease and conventional treatments do not have a major impact on the prognosis in these patients. Therefore, utilization of new methods of treatment with lower adverse effects can cause higher survival rates. In this study, the in vitro ef...
This experiment was conducted to evaluate the effects of foliar application of different K:Ca ratios (0, 0.5, 1 and 1.5) on growth parameters, yield and fruit quality of strawberry 'Selva' in greenhouse conditions based on completely randomized design with three replicates. Based on the results, spray application showed significant effects on the photosynthetic capacity, enzymatic and non-enzym...
with the increasing population and the need for more food, as well as with the development of science and technology, human approach to unnatural and often chemical inputs to increase agricultural production has been a great expansion and problems such as increased cancers, chronic diseases has created environmental pollution. implementation of organic organic is a solution to these problems . ...
