This study was conducted to evaluate the effects of paclobatrazol and cycocel on some quantitative and qualitative traits of zinnia. Seedlings were transplanted on Horticulture Department Farm , College of Agriculture, Isfahan University of Technology. The experiment was carried out in the framework of randomized complete block with 3 replications. Triats which were studied included plant heigh...

آویشن دنایی یک گیاه دارویی بومی ایران است که متعلق به نعنائیان (Labiatae) می‌باشد. این گیاه به‌طور گسترده در طب گیاهی و صنایع غذایی استفاده می‌شود و حاوی متابولیت‌های ثانویه (کارواکول و تیمول) می‌باشد. تنش خشکی، رشد و متابولیسم این گیاه را تحت تاثیر قرار می دهد. در این تحقیق اثر سطوح مختف تنش خشکی شامل شاهد (100 درصد ظرفیت مزرعه‌ای)، تنش ملایم (50 درصد ظرفیت مزرعه‌ای) و تنش شدید خشکی (25درصد ظر...

Biofertilizers are important sources for plants' supplementing nutrition program, which have significant effect on reduction of costs and adverse effects of mineral fertilizers on the environment. This research was conducted as two different experiments. In experiment 1, effect of biofertilizer (0, 1 and 1.5 L nitroxin/ 500 m2), paclobutrazol (0, 25 and 50 mg/L) with/without pinching, and in ex...

Drought stress is a limiting factor for production in agriculture. In order to evaluate the impact of plant growth regulators, Salicylic acid and Paclobutrazol on growth and physiological traits of Sweet Basil (Ocimum basilicum) under drought stress condition, a factorial pot experiment based on Randomized complete design with 4 replication was carried out at research greenhouse of Mohaghegh Ar...

Drought stress is one of the limiting factors for plant growth and yield all over the world. Stevia rebaudiana from semi-humid area of Paraguay contains steviol glycosides with pharmacological properties. In the present study, the callus obtained from Stevia rebaudiana were treated with different treatments of poly ethylene glycol, paclobutrazol and gibberellin under in vitro culture and then s...

This study was carried out to evaluate the effects of Gibberellic acid and Paclobutrazol respectively on promote flowering and vegetative growth reduction in strawberry in order to enhance production. Gibberellic acid and paclobutrazol are plant growth regulators. Gibberellic acid can act as a promoter while, paclobutrazol act as an inhibitor. Gibberellic acid at 100 mg/l, 30 and 90 days and pa...
