SEED GERMINATION AND SEEDLING GROWTH OF SUNFLOWER (Helianthus annuus L.) UNDER SALT STRESSED CONDITIONS

نویسندگان

چکیده

The experiment was conducted during October 2014 to December evaluate the effect of different levels salinity on seed germination and seedling growth sunflower. factorial consists three variety sunflower such as BRAC HySun 33, BARI sunflower-2, KU SL-1 five viz. 4, 8, 12, 16 dS m-1 with control. salt stress were varied significantly. (germination energy, capacity speed germination) parameters (root length, shoot length growth) significantly affected by gradually declined increasing levels. Hysun 33 (V1) showed better performance upto 12 m 1 in laboratory condition.

Sunflower (helianthus Annuus L.) Response to Drought Stress at Germination and Seedling Growth Stages

Response of six sunflower hybrids/ breeding lines viz., G-101, SF-187, Hysun-33, Hysun-38, 64A-93 and S-278 to drought stress imposed at germination and seedling growth stages was investigated in a laboratory experiment (25±3C). Five water stress levels of zero (control), -0.35, -0.6, -1.33, and 1.62 MPa were developed using polyethyleneglycol-6000 (PEG-6000). Complete randomized design with th...

Effect of salinity on seed germination, seedling growth, and inorganic and organic solutes accumulation in sunflower (Helianthus annuus L.)

To investigate the effects of saline stress on seed germination, ion distribution, and organic solutes changes of sunflower (Helianthus annuus L.), in the present study, seeds and 3-week-old seedlings were subjected to a series of external NaCl concentrations (5–200 mmol). The results showed that high salinity (200 mmol) remarkably inhibited the germination of seed and delayed germination time ...

Effects of Salinity, Temperature, and Polyethylene Glycol on the Seed Germination of Sunflower (Helianthus annuus L.)

Salinization has severe influences on agriculture in the whole world. The main aims of this work were to evaluate osmotic effect and ion effect of NaCl on seed germination of three sunflower (Helianthus annuus L.) cultivars interacting with three alternating temperature regimes and to select the most salt tolerant cultivars to plant in the saline region. Seeds were germinated in the isotonic Na...

Priming-induced metabolic changes in sunflower (Helianthus annuus) achenes improve germination and seedling growth

Seed priming improves vigor, but priming agents may differ greatly in their effectiveness. The present study was performed to unravel the physiological basis of vigor improvement by priming sunflower achenes with pre-optimized levels of hydrogen peroxide (H2O2), salicylic acid (SA), thiourea (TU), gibberellic acid (GA3), ascorbic acid (AA), sodium chloride (NaCl), freezing and heating. Most of ...

Incorporation of Polyamines in the Priming Media Enhances the Germination and Early Seedling Growth in Hybrid Sunflower (Helianthus annuus L.)

A laboratory study was conducted to evaluate the benefits (if any) associated with the incorporation of polyamines in the priming media for hybrid sunflower achene priming. Achenes were subjected to hydropriming for 24 h and in the solutions containing 10 mg L spermidine and putrescine for 24 h. All the achene priming treatments resulted in improved germination and early seedling growth. Primin...
