Impact of salinity on seed germination and early establishment of field dodder (Cuscuta campestris Yunck.)

effect of seed priming and irrigation regimes on yield,yield components and quality of safflowers cultivars

این مطالعه در سال 1386-87 در آزمایشگاه و مزرعه پژوهشی دانشگاه صنعتی اصفهان به منظور تعیین مناسب ترین تیمار بذری و ارزیابی اثر پرایمینگ بر روی سه رقم گلرنگ تحت سه رژیم آبیاری انجام گرفت. برخی از مطالعات اثرات سودمند پرایمینگ بذر را بر روی گیاهان مختلف بررسی کرده اند اما در حال حاضر اطلاعات کمی در مورد خصوصیات مربوط به جوانه زنی، مراحل نموی، عملکرد و خصوصیات کمی و کیفی بذور تیمار شده ژنوتیپ های م...

The effect of salinity on seed germination, early seedling growth and anatomical structure of Beta vulgaris

Beta vulgaris belongs to the family Amaranthaceae and was found to have halophytic ancestors. The objective of this study was to investigate the effect of sodium chloride on seed germination, therefore the early stages of seedling growth of Beta vulgaris grown under different salinity levels (0, 100, 150 and 200 mM of NaCl) were studied. The experiment was laid out in a completely randomized de...

Effect of Magnetic Field on Seed Germination and Early Growth of Calendula officinalis L.

 In order to study on effect of magnetic field on germination characteristics and early growth of marigold (Calendula officinalis L.) seeds an experiment was carried out in laboratory conditions in Arak University of Iran. Seeds were magnetically exposed to magnetic field strengths, 100 or 200 mT for different periods of time; D1 (control), D2 (1 h), D3 (6 h), D4 (12h), D5 (24 h) and D6 (contin...

allelopatic effect of different caster bean organs (ricinus communis l.) on reducing germination and growth of dodder (cuscuta campestris yuncker)

introduction dodder (cascuta campestris yuncker) is an annual parasitic plant from the convolvulaceae family (mishra et al., 2007). it wraps around many adjacent dicot and a few monocot plants, penetrates in their vascular tissue and exploits photosynthates, nutrients and water (lanini & kogan, 2005). consequently, the growth, vigor and production of the host plant will be severely reduced (nad...
