molecular and physiological characterizations of floral scent production in rosa damascena mill.
گل محمدی (r. damascena mill.)مهمترین گونه ای است که در تولید گلاب، عطر و اسانس، در صنعت عطرسازی و دارویی کاربرد دارد. با وجود اهمیت عطر گل محمدی، پژوهش های مولکولی و بیوشیمیایی عطر گل این گونه هنوز در مراحل ابتدایی است. در این پژوهش، ویژگی های مولکولی و فیزیولوژیکی تولید عطر در گل محمدی در آزمایش های مختلف مورد بررسی قرار گرفتند. در آزمایش اول، پژوهشی به منظور بررسی تنوع شیمیایی اسانس میان 44 ت...
The Reaction Controlling Floral Initiation.
Reproduction in many plants and animals is controlled by the length of the night and the cycle of day and night. A dark reaction affords the measure of time and this reaction can be quickly stopped or reversed by light such as that from the rising sun. The reaction is possibly universal in living forms but its more extreme and evident manifestation is recognized to a rather limited extent. Thus...
متن کاملRegulation of floral initiation in horticultural trees.
The intention of this review is to discuss floral initiation of horticultural trees. Floral initiation is best understood for herbaceous species, especially at the molecular level, so a brief overview of the control of floral initiation of Arabidopsis (Arabidopsis thaliana (L.) Heynh.) precedes the discussion of trees. Four major pathways to flowering have been characterized in Arabidopsis, inc...
متن کاملGriesel-floral Primordia Initiation in Cestrum
in this report that C. nocturnum is both LD and LSD in its responses and that the previously reported critical day length is for the LD responses while the LSD response has a critical day length of between 12 and 16 hours. This more clearly defining of the 2 responses in C. nocturnum brings into focus the previously suggested questions as to whether a single hormone can he synthesized as a resu...
متن کاملManipulation of Floral Symmetry Does Not Affect Seed Production in Impatiens Pallida
The outcomes of past research concerning the role of floral symmetry in plant-pollinator interactions are mixed. Field manipulations of plants, as well as experiments using artificial arrays, have found evidence for and against a direct relationship between the degree of floral symmetry and subsequent reproductive success. In this study, we test the hypothesis that deviations from perfect flora...
