Changes in Physiological and Biochemical Parameters of Gourd (Cucurbita pepo L.) Two Varieties under Drought and UV-B Radiation. Nobar Hajihosseinlo*, Siavash Hosseini Sarghein and Rashid Jamei
It emerged recently that there is an inter-relationship between drought and Ultraviolet-B (UV-B) radiation in plant responses, in that both stresses provoke an oxidative burst. The objective of the present investigation was to study the effect of drought stress, UV-B radiation and the combined effects of UV-B and drought stresses on two cultivars of gourd seedling. The gourd plants were grown w...
متن کاملStudy of phytohormones effects on UV-B stress seeds of thyme species
Background & Aim: Thymus vulgaris L. and Thymus daenensis Celak (Thyme), members of the family Lamiaceae, are widely used in Iranian folk medicine. The aim of this research was to study how salicylic acid (SA), gibberellin (GA), and indole acetic acid (IAA)-seed priming affect UV-B radiation in seeds of Thyme (T. vulgaris, T. daenensis </...

متن کاملThe Impact of UV-B Radiation on Some Metabolites and Pigments of Carum Copticum Under In vitro Culture
Carum copticum L. is a medicinal plant of the Apiaceae family with medicinal properties. In this study, the effects of UV-B radiation on the photosynthetic pigments and essential oils as well as phenols and anthocyanin of the seedling and callus of C. copticum were investigated under in vitro conditions. For this purpose, the experiment was set up in a completely randomized design, with three r...

Drought stress and ultraviolet radiation as stressful environmental factors have deleterious effects on physiological and growth of plants. Plants through specific physiological mechanisms confront with stressors factors that they cause the production of reactive oxygen species in plant cell. So in order to evaluation of the effect of drought stress and Ultraviolet on photosynthesis pigments an...
