Abstract Elucidating the regulatory mechanisms of environmental factors on seed dormancy and germination will provide guidance for tree regeneration. Toward understanding coupled effect light temperature release Pinus koraiensis seeds, we set up three conditions (L200: 200 μmol m −2 s −1 , L20: 20 L0: 0 μ ) four storage temperatures [T-5: − 5 °C (50 days), T5: days) + T25: °C(50 25 T15: 15 days...
abstract the present study was conducted to investigate the effect of using model essays on the development of writing proficiency of iranian pre-intermediate efl learners. to fulfill the purpose of the study, 55 pre- intermediate learners of parsa language institute were chosen by means of administering proficiency test. based on the results of the pretest, two matched groups, one as the expe...
BACKGROUND AND AIMS Despite the intense interest in phenological adaptation to environmental change, the fundamental character of natural variation in germination is almost entirely unknown. Specifically, it is not known whether different genotypes within a species are germination specialists to particular conditions, nor is it known what physiological mechanisms of germination regulation vary ...
introduction: diabetes mellitus is an growing national and international public health concern. the number of people affected by diabetes in world by 2030 will be 69% in developing countries. regular physical activity plays a key role in the management of type 2 diabetes melitus, particularly glycemic control. it has been recommended that peoples with type 2 diabetes participate in moderate-int...
abstractof two mcall programs introducing 100 vocabulary items through two im the researcher of the present study was intrigued to compare the effects age modalities (pictures and streaming video) with those of a conventional method (teacher instruction) in an efl context. she set out to investigate whether such multimedia environments could provide a more effective environment for vocabulary...
Effects of application in vivo of glyphosate, fluridone, and paclobutrazol to glasshouse-grown donor plants of Pennisetum purpureum Schum. on endogenous levels of abscisic acid (ABA) and indole-3-acetic acid (IAA) in young leaves and on somatic embryogenesis in cultured leaf explants were studied. Treatment of plants with glyphosate (100 milligrams per liter) resulted in elevated levels of endo...
Background: Gibberellic acids are naturally occurring plant hormones that are used in agriculture as plant regulators and enter animals and human cells through diet. This study was undertaken to investigate effects of gibberellic acid on testicular tissue of adult rats. Materials and Methods: Twenty seven adult male Wistar rats after a one week acclimatization period were randomly divided into ...
The fungus Cercospora rosicola produces abscisic acid (ABA) as a secondary metabolite. We developed a convenient system using this fungus to determine the effects of compounds on the biosynthesis of ABA. Inasmuch as ABA and the gibberellins (GAs) both arise via the isoprenoid pathway, it was of interest to determine if inhibitors of GA biosynthesis affect ABA biosynthesis. All five putative inh...
Abstract Ninebark is a very popular ornamental shrub. Micropropagation an efficient method for mass production of uniform plant material. This study was designed to develop and optimize conditions at all phases ninebark micropropagation. For the multiplication stage, Murashige Skoog (MS) medium full concentration pH 5.8 chosen as basal medium. Sorbitol proved more effective carbohydrate source ...
abstract the following study, in the first place, attempted to examine the effect of less experienced teachers participation in experienced teachers classes on their own skills and teaching methodology, in the second place, attempted to find out the role of teachers training in students achievements. for this purpose, 21 efl teachers were selected according to available sampling in kish l...
