Influence Of Nutrient Concentrations And Nacl Salinity On The Growth, Photosynthesis, And Essential Oil Content Of Peppermint And Lemon Verbena, S. J. Tabatabaie, J. Nazari
Influence Of Nutrient Concentrations And Nacl Salinity On The Growth, Photosynthesis, And Essential Oil Content Of Peppermint And Lemon Verbena, S. J. Tabatabaie, J. Nazari
Turkish Journal of Agriculture and Forestry
Growth and essential oil content of peppermint (Menhta piperita var. officinalis) and lemon verbena (Lipia citriodora var. Verbena) were evaluated in response to salinity and nutrient solution concentrations, measured as electrical conductivity (EC 0.7, 1.4, 2.8, 5.6, and 5.6_{Na} dS m^{-1}). In peppermint, the highest fresh weight and dry weight were observed in the 1.4 dS m^{-1} treatment. The increased EC with either NaCl or all nutrients at 5.6 dS m^{-1} reduced the fresh weight of lemon verbena. The maximum fresh weight and dry weight in lemon verbena were obtained in both 1.4 and 2.8 dS m^{-1} treatments. Increasing EC …

Effect Of 28-Homobrassinolide On Salinity-Induced Changes In Brassica Juncea, Shamsul Hayat, Barket Ali, Syed Aiman Hasan, Aqil Ahmad
Turkish Journal of Biology
Seedlings of Brassica juncea Czern & Coss cv. Varuna generated from seeds soaked in 0, 50, 100, or 150 mM NaCl for 6 h were treated with 0, 10^{-10}, 10^{-8}, or 10^{-6} M 28-homobrassinolide (HBL) after 14 days of growth. Plants that received only NaCl treatment exhibited a decrease in nitrate reductase and carbonic anhydrase activity, chlorophyll content, and P_N 60 days after sowing (DAS), and decreased seed yield at harvest (140 DAS). Subsequent treatment with HBL significantly increased all of the above parameters. The 10^{-8} M concentration of HBL generated the best response and also overcame the detrimental effects …
