  • Use of Morpho-physiological Parameters and Biochemical Markers to Select
           Drought Tolerant Genotypes of Durum wheat

    • Authors: Ismail Outoukarte; Abderrahim El Keroumi, Abdelhi Dihazi, Khalid Naamani
      Abstract: Nine durum wheat genotypes (Karim, Ourghi, Massa, Isly, Vitron, Sebou, Oum Rbia, Sarif, and Marzak) were grown in pots and evaluated for their phenolic content and peroxidases activity (POX), cell membrane stability (CMS) and Stomatal Resistance (SR). The genotypes Ourghi and Karim exhibited the highest amount of total phenolics (1374 µg.g-1 FW and 1303 µg.g-1 FW respectively) while Massa and Oum Rbia showed the lowest amounts (676 µg.g-1 FW and 761 µg.g-1 FW respectively) under severe stress regime. High performances Liquid Chromatography (HPLC) analysis revealed an important accumulation of hydroxycinnamic acid derivatives for the most accumulating genotypes. Under severe drought stress conditions, Ourghi revealed the highest peroxidase activity and Oum Rbia the lowest. A positive correlation was obtained between total phenolics and CMS. In another experiment hold in the hydroponic system under normal growing conditions, we revealed the superiority of genotype Karim in term of tillers, leaves and roots number, root thickness and dry matter accumulation and allocation to the roots. The present data provide useful information about whether the parameters used in this study are helpful in understanding drought tolerance mechanisms and the possibility to use them in selection programs under Mediterranean conditions.

    • Authors: A. Natarajan; P. Vijayarengan, M. Vijayaragavan
      Pages: 04 - 06
      Abstract: The increasing concentrations (10, 25, 50, 75 and 100 mg /kg) of soil cadmium on growth and biochemical contents in tomato plants were analysed on 30th sampling days. Control plants were maintained separately. Plants were grown in pots containing 3 kg of air dried sandy loam soil and treated with different concentrations (mg/kg) of cadmium (0, 10, 25, 50, 75 and 100 ). Treatments decreased the growth parameters such as root and shoot length  and biochemical constituents such as, protein,(except, proline and  phenol content) contents in tomato plants compared to untreated plants. The shoot length of cadmium treated tomato plants was higher than the root length. proline and phenol content of root of  tomato plants was higher than the shoot.

  • Salt stress mitigation by salicylic acid in wheat for food security in
           coastal area of Bangladesh

    • Authors: Sayed Abdul Akher, Md Nazirul Islam Sarker, Shamima Naznin
      Pages: 07 - 16
      Abstract: Salt stress has a large impact on controlling the plant growth and development. The present study was conducted to examine the role of salicylic acid on alleviation of salt stress in wheat. In this experiment, the treatment consisted of four different salinity levels viz. S0 = without salt (control), S1 = 2.8 g NaCl kg-1 soil ' 3-4 dSm-1, S2 = 6.0 g NaCl kg-1 soil ' 7-8 dSm-1, S3 = 9.0 g NaCl kg-1 soil ' 11-12 dSm-1 and three different levels of salicylic acid (SA) viz. A0 = 0 mM, A1= 0.2 mM and A2 = 0.4 mM. It was done by using two factors Randomized Complete Block Design (RCBD) with four replications. The total treatment combinations were 12 (4x3). Results of the experiment showed a significant dissimilarity among the treatments in respect of the major parameters. Yield of wheat were exaggerated by different levels of salinity. The higher levels of salinity showed greater reduction of yield. The highest grain yields (1.55 tha-1) were recorded at S0A2 (Without Salt + 0.4 mM salicylic acid) treatment combination which did not show any difference with S0A0 (Without Salt+ Without SA) and S0A1 (Without Salt + 0.2 mM SA). But the grain yield was gradually decreased with the increasing level of salinity. The application of salicylic acid increased the grain yield differently according to the levels of salinity. The minimum grain yields were found 1.14 t ha-1, 1.07 tha-1 and 0.26 t ha-1 at 3-4 dSm-1, 7-8 dSm-1 and 11-12 dSm-1 NaCl respectively. These yields were increased with SA (0.4 mM) from 1.14 to 1.32 tha-1, 1.07 to 1.14 tha-1 and 0.26 to 0.31 tha-1 at 3-4 dSm-1, 7-8 dSm-1 and 11-12 dSm-1 NaCl respectively. These results suggest that salicylic acid can alleviate the detrimental impacts of salinity and increase the grain yield of wheat.

    • Authors: S. Mudhalvan; N. Senthilkumar
      Pages: 41 - 44
      Abstract: A study was conducted for identifying the genetic divergence in okra (Abelmoschus esculentus (L.) Moench) genotypes.  Fifteen genotypes were evaluated with the objective of selecting superior genotypes namely, Arka Anamika, Varsha Upahar, Thunder, Dhanya, Pusa-7, Basanthi, S-51, Thanvi-66, CO-2, Akshaya, N-U-Lakshmi, Namadhri, PHS, Villupuram Local, and Karur Local for fruit yield traits. The degree of divergence among 15 genotypes was computed using Mahalanobis’ D2 analysis to assess the genetic diversity. For this programme, morphological characters viz., days to first flowering, plant height, inter node distance, days to fruit maturity, number of immature seeds per fruit, fruit length, fruit girth, number of branches per plant, number of fruits per plant, fruit weight, and fruit yield per plant were studied. Analysis of variance for 15 genotypes of bhendi revealed that all the genotypes were   significantly differed among themselves for all the eleven traits studied. The results revealed that the mean performance for fruit yield per plant was maximum in the genotype namely Basanthi(465 g),  followed by Dhanya(438 g), and S-51(433 g). The genotypes which recorded high mean performance for fruit yield per plant also exhibited significant per se performance for the traits namely inter node distance, number of fruits per plant and average fruit weight.

      Abstract: Phytosociological study was carried out to estimate the dominant of weed flora in low land rice eco-system under varing climatic condition. The survey was conducted at Annamalai University experimental farm, Department of Agronomy, Annamalainagar during 2016 and 2017. The identified numbers were 11 and 14 during 2016 and 2017 wet season. Cyperus rotundus, Cyperus irria, Cyperus difformis, Echinocoloa colonum, Eclipta alba, Echinocoloa crusgali were the densely populated in 2016 while Cyperus rotundus, Cyperus irria, Echinocoloa colonum, Cyperus difformis, Marsilia quatrifolia,  Echinocola crusgali and Bergia capensis, were the most densed in 2017. IVI computed for individual weed species in 2016 at annamalai nagar indicated that Cyperus rotundus was the predominant weed species with highest Relative abundance (RA) of 10.54 %, Relative density (RDE) of 18.97%, Relative frequency (RF) of 16% and Important value index (IVI) of 45.50 while in 2017 also obtained the Cyperus rotundus was the predominant weed species with highest Relative abundance (RA) of 10.61 %, Relative density (RDE) of 19.64%, Relative frequency (RF) of 1615.38% and Important value index (IVI) of 45.63. All other weed species were low in IVI and also rare in their occurrence with lesser frequency.
