Establishment of seedlings at early growth stages of crop plants as one of the most important determinants of high yield is severely affected by soil salinity. Therefore, high germination rate and vigorous early growth under saline soils is preferred. In this study 15 wheat (Triticum aestivum L.) cultivars were used to investigate the effects of three salinity concentrations including 4, 8 and ...

The natural occurrence of free cytokinins was examined in relation to the growth of serially propagated pea-root callus tissue cultures. The relatively slow-growing pea-root callus was harvested at regular intervals throughout a 12-week period and fresh weight, dry weight, cell number, and cytokinin activity were determined. At the end of the culture period the fresh weight had increased about ...

In the present study, the effect of seaweed liquid fertilizer (SLF) of Ulva fasciata, Nizimuddinia zunardini and Gracilaria corticata without chemical fertilizer on seed germination, growth parameter, pigment and carbohydrate content of Wheat var. (Chamran) was investigated. The seeds soaked with aqueous extract of seaweeds performed better when compared to the water soaked controls. The 10% co...

Frequency of irrigation to the crops is the key factor for proper growth and economic yield. Therefore, in the current study growth of broccoli plants was investigated under different irrigation levels in pot culture condition. Five levels of irrigation schedules were applied including I0 [Non-irrigation control], I1 [Irrigation up to 15 days after transplanting (DAT)], I2 [Irrigation up to 30 ...

This experiment was conducted to determine allopathic effects of Cyperus rotundus extracts on the tomato germination. It was a completely randomized design (CRD) with four replications, carried out in the laboratory of the Agricultural College of University Jiroft during 2011. The various test treatments were extracts of Cyperus rotundus taken from aerial organs, root, and com...

this research evaluated the effects of gibberellin (ga3) and abscisic acid (aba) on emergence capability, rate of emergence, vigor index and some physiological characters of chickpea seedling (cicer arietinum l.) in a field experiment (as split) under dry and irrigated conditions. seeds were primed with 0, 50, 100 and 150 ppm of each phytohormones. examined chickpea cultivar was azad. the resul...

Responses of barnyardgrass (Echinochloa crus-galli var. crux-galli) to water drained, saturated, or flooded soils were assessed in relation to the aerenchyma formation in crown roots. Plant height, fresh weight of shoots, the number of crown roots, and the fresh weight of roots of 4-week-old barnyardgrass increased in the following order: saturated>drained>flooded. By contrast, aerenchyma was r...
