For maintaining a steady food supply, the trend has been toward developing factorylike production methods in Japan. To date, there has been no indicator that can predict the growth status of crops. We have accordingly focused on the bioelectric potential inside the plant, which could be an indicator of plant growth. However, a few research studies have been conducted on its role in determining ...
rangelands have been composed of different plant species that emergence of phenological stages in every one of them will be influenced by environmental and genetic factors. in order to exploit the time and achieve acceptable performance in each plant species, it is necessary that the emergence of biological phenomena are recorded and studied. the objective of the present study is to survey the ...
The present study was carried out to evaluate the effects of light and plant growth regulators on callus induction and explant browning in date palm cultivar, Estameran in in vitro condition. The explants were pretreated by an antioxidant combination (100 mgl-1 citric acid and 150 mgl-1 ascorbic acid) for 3 days in 5 °C. Then, the leaf explants were cultured in Murashige and Skoog medium (MS)...
In order to investigate the best planting time and rice cultivars for the conditions in Khuzestan Province, seven high quality cultivars of rice namely Domsiah, Binam, Ramasanali Tarom, Sang Tarom, Hasansarai, Tarom Mahalli, Daylamani and Anboori were selected and studied in 4 planting dates starting in Mid-May, with intervals of 15 days. The experiment was conducted as a split plot design in r...
To investigate the effects of sowing date on yield and some physiological index of six forage maize cultivars in Rasht region, a field study was conducted in 2010. The experimental design was randomized complete blocks with factorial arrangement with three replications. Treatment consisted of four levels of sowing date (22 May, 3, 15 and 25 June), and six maize cultivars (SC 260, DC 370, SC 500...

in a completely randomized design, the effect of the extract from trifolium alexandrium (0, 0.2 and 0.4%) on the germination, some morphological characteristics, photosynthetic pigments, and nutrients uptake of prosopis cineraria was evaluated. the highest germination rate and percentage (9.16 and 21%, respectively) were recorded in the 0.2% treatment. the maximum and minimum lengths of radicle...
Dubas bug, Ommatissus lybicus de Bergevin (Hem.: Tropiduchidae), is a key pest of date palms in Iran.This pest was first reported on date palms in 1966 and has been established throughout the date producing regions in southern Iran since. Date palm is the only host plant of Dubas bug. It attacks almost all date palm varieties, esp. Mazafati variety in city of Bam, Kerman Province and other vari...
In order to study the effects of irrigation and planting date on selected traits of ajowan (Carum copticum BENTH. & HOOK.F.) an experiment was conducted in two successive conducive seasons of 2009/2010 and 2010/2011 in Birjand. The experimental design was a split plot based on randomized complete block with three replications. In the present study, two irrigation treatments (irrigation terminat...
faba bean is one of the proper crops for cultivation in guilan climate conditions in rotation with rice. one of the limiting factors in development of cultivating this plant is late maturity and synchronizing of its ripening with rice transplanting. to investigate the effect of planting date, timing and consumption rate of paraquat herbicide on the ripening, grain yield and some of the agronomi...
