28-homobrassinolide Induced Changes Favoured Germinability of Wheat Grains
The surface sterilized grains of Triticum aestivum (L.) cv. HD2204 were soaked in graded concentration (10–10, 10–8 or 10–6) of 28-homobrassinolide (HBR), for 8 h. These pre-treated grains were transferred to sterilized petriplates, lined with filter paper moistened with double distilled water in a B.O.D. incubator, fixed at 25°C. The samples were removed 12, 18 and 24 h of their initial soakin...
متن کاملResponse of Germinating Seeds of Cicer Arietinum to 28-homobrassinolide And/or Potassium
The involvement of ionic channel/s in signal transduction and the amplification of phytohormones induced impact on the processes leading to seed germination provoked us to undertake the present study. Seeds of Cicer arietinum (L.) cv. Avarodhi were soaked in the aqueous solutions of 28homobrassinolide (HBR) and/or K+, for a limited period, and subsequently transferred to distilled water, for th...
متن کاملInteractive Effect of 28-homobrassinolide and Salinity on Morpho-physiological Attributes of 60 Day Old Brassica Juncea Plants
Among various environmental stresses, salt stress is an extensively damaging to major crops all over the world. A set of experiments was conducted to examine the role of 28-homobrassinolide on growth and photosynthetic pigments of salt tolerant Brassica juncea cultivar RLC-1 under control or saline conditions i.e., 0 or 180 mM of NaCl. Surface sterilized seeds of B. juncea were given pre-sowing...
متن کاملEffect of 28-homobrassinolide on the nitrate reductase, carbonic anhydrase activities and net photosynthetic rate in Vigna radiata
The foliage of fifteen day-old Vigna radiata seedlings was sprayed with water (control) or with a 10–10 M, 10–8 M or 10–6 M aqueous solution of 28-homobrassinolide (HBR). Samples of the treated plant material, collected at 30/50 days after sowing (DAS), were assessed for the activities of carbonic anhydrase (CA) and nitrate reductase (NR); leaf chlorophyll content (Chl); stomatal conductance (g...
متن کاملEffect of 28-homobrassinolide on growth, zinc metal uptake and antioxidative enzyme activities in Brassica juncea L. seedlings
The present work was undertaken to study the effects of 28-homobrassinolide on growth, zinc metal uptake, antioxidative enzyme [guaiacol peroxidase (EC 1.11.1.7), catalase (EC 1.11.1.6), glutathione reductase (EC 1.6.4.2), ascorbate peroxidase (EC 1.11.1.11), superoxide dismutase (EC 1.15.1.1)] activities and protein content in 7-d-old seedlings of Brassica juncea L. treated with Zn metal at di...
