Aqueous solutions of salicylic acid (SA) were applied to the foliage of 30-d-old plants of mustard (Brassica juncea Czern & Coss cv. Varuna). The plants sprayed with the lowest used concentration (10−5 M) of SA were healthier than those sprayed with water only or with higher concentrations of SA (10−4 or 10−3 M). 60-d-old plants possessed 8.4, 9.8, 9.3,(More)
Plants of Brassica juncea L. cv. T-59 were supplied with 50 or 100 µM nickel (Ni50, Ni100) at 10 d after sowing (DAS), and sprayed with 28-homobrassinolide (HBR) at 20 DAS. The plants treated with Ni alone exhibited reduced growth, net photosynthetic rate, content of chlorophyll, and the activities of nitrate reductase (E.C.1.6.6.1) and carbonic anhydrase(More)
The present piece of work highlights the comparative effects of two active forms of brassinosteroids (BRs), 28-homobrassinolide (HBL) and 24-epibrassinolide (EBL), on growth parameters, carbonic anhydrase activity and photosynthetic parameters in Lycopersicon esculentum (cv. K-21) sampled at 45 (24 h after spray) and 60 days after sowing, under natural(More)
Thirty-day-old plants of mustard (Brassica juncea L.) were sprayed with 10−10, 10−8, or 10−6 M aqueous solution of 28-homobrassinolide (HBR). The HBR-treated plants were healthier than those treated with water and yielded more. Maximum increase over control was found in 60-d-old, 10−8 M-HBR-treated plants in fresh and dry mass per plant, carbonic anhydrase(More)
An experiment was conducted under controlled conditions, in which grains of wheat (Triticum aestivum L. cv. Raj-3077) were soaked in 0, 1, 3 and 5 µM aqueous solutions of 28-homobrassinolide (HBR) for 4, 8 and 12 hours. The seedlings raised from the grains pre-treated with HBR possessed significantly higher leaf number, fresh and dry weight·plant−1, nitrate(More)
The ameliorative role of 28-homobrassinolide under chilling stress in various growth, photosynthesis, enzymes and biochemical parameters of cucumber (Cucumis sativus L.) were investigated. Cucumber seedlings were sprayed with 0 (control), 10−8, or 10−6 M of 28-homobrassinolide at the 30-day stage. 48 h after treatment plants were exposed for 18 h to(More)
Brassinosteroids (BRs) are polyhydroxylated steroidal plant hormones that play pivotal role in the regulation of various plant growth and development processes. BR biosynthetic or signaling mutants clearly indicate that these plant steroids are essential for regulating a variety of physiological processes including cellular expansion and proliferation,(More)
To investigate the effect of exogenously applied 28-homobrassinolide (HBL) on drought-stressed plants, photosynthesis and antioxidant systems were examined in Indian mustard (Brassica juncea L.). Seedlings of Indian mustard were subjected to drought stress for 7 days at the 8–14 (DS1)/15–21 (DS2) days’ stage of growth and then returned to normal conditions(More)
The jet energy scale (JES) and its systematic uncertainty are determined for jets measured with the ATLAS detector using proton–proton collision data with a centre-ofmass energy of √ s = 7 TeV corresponding to an integrated luminosity of 4.7 fb−1. Jets are reconstructed from energy deposits forming topological clusters of calorimeter cells using the anti-kt(More)
An interactive effect of nitric oxide and 24-epibrassinolide (EBL) or 28-homobrassinolide (HBL) was investigated in Lycopersicon esculentum Mill. cv. K-21. Seeds prior to sowing were exposed to sodium nitroprusside (SNP) (0, 10−5 M or 1 M), a nitric oxide donor, for 8 h, and the resulting seedlings were subsequently sprayed with 10−8 M EBL or HBL at 30-day(More)
