تحقیق حاضر به منظور پیش¬رسـی و کوتـاه نمودن دوره گلـخانه و بررسی شـاخص¬های کمی و کیفی رشد و گلدهی نرگـس دروغین در سال 1392 در طرح دو عاملی و به صورت کاملاً تصادفی با سه تکرار در گلخانه¬ای از توابع شهرستان تنکابن انجام گرفت. گروه اول پیاز¬ها به مدت 12 هفته و گروه دوم به مدت 15 هفته، تحت دمای 9 درجه سانتی¬گراد تیمار شدند. فاکتور دوم شامل جیبرلیک اسید با چهار سطح صفر (آب مقطر)، 250، 500، 750 پی پی ...
The germinatioil of seed can be controlled by ap)plication of exogenous hormones at physiological concenitrations. It is therefore possible that the n-atural control of germination involves an interplay of hormones, both promoters and inh,,ibitors. WXe have shown that cytokinins overcome the inhibitoryaction of several natural inhibitors in the germination of the photosensitive Grand Rapids let...
In the present study, synthetic seed production of medicinally important plant Enicostema axillare through nodal and root explants were attempted. plantlets germinated seeds using in vitro explants. Synthetic prepared from 3% Na+ 100mm calcium chloride was optimum concentration for uniform compact synseed formation. Alginate beads containing derived successfully entrapped with sodium alginate h...

To improve Agrobacterium-mediated transformation of tobacco, factors influencing gene delivery, including genotype of the plant, bacterial strain, and Agrobacterium transformation procedure, were tested via direct somatic embryogenesis. Leaf tissue of three different tobacco genotypes (Nicotiana tabacum L. cvs. Samsun, and Xanthi, and N. benthamiana) we...
Gamma-linoleic acid in the seed oil of evening primrose makes it nutritionally and pharmaceutically valuable. If evening primrose wants to be cultivated as an annual plant, sowing time is important. By the late sowing and depends to time most plants do not produce flower stem and stay in rosette stage until next spring. To solve this problem, the present study was performed. Seedling were trans...
effect of gibberellic acid on marigold (calendula officinalis l.) was evaluated in a pot culture experiment. a factorial experiment based on completely randomized design including 12 treatments and four replications was carried out. main factor was foliar application stages (first, second and third) and sub factor included different concentrations of ga3 (0, 50, 150 and 250 mg l-1). results sho...
Aims. The Herschel-ATLAS survey (H-ATLAS) will be the largest area survey to be undertaken by the Herschel Space Observatory. It will cover 550 sq. deg. of extragalactic sky at wavelengths of 100, 160, 250, 350 and 500 μm when completed, reaching flux limits (5σ) from 32 to 145 mJy. We here present galaxy number counts obtained for SPIRE observations of the first ∼14 sq. deg. observed at 250, 3...
Gentiana lutea L. is widely used in bitter beverages and in medicine; Gentianae Radix is the pharmaceutical name of the root of G. lutea. These uses have generated a high demand. The wild populations of Gentiana lutea var. aurantiaca (M. Laínz) M. Laínz have been decimated; it is necessary to establish guidelines for its cultivation. Gentian as most alpine species has dormant seeds. Dormancy ca...
