Therefore, the present study has focused on exploring the time course of infection and disease development in the field including the potential of seed transmission. genotypes under salt stress. Brassica juncea has been distributed worldwide as a crop, and has escaped cultivation to become naturalized in fields, wasteland and roadsides as a weed. Morphology of pollen grains as, pollen size, shape, exine thickness and ornamentation characters are very useful in plant identification. The improved physiological efficiency of paclobutrazol-treated plants in the light of above morphological and anatomical modifications is discussed. Moreover, compatible solutes at higher concentrations can reduce inhibitory effects of ions on enzymes activity and do not disturb intercellular biochemistry (Bohnert and Jensen 1996). Genotype G4 performed poorly. Figure 7. Purple kohlrabi (Brassica oleracea L. var. The total N content was determined according to the method of Lindner (1944). and control during both the years. B.juncea is distinct from its close relatives B. napus and B. rapa in that the upper leaves of B. juncea are not clasping. Besides, the role of salicylic acid (SA) in resistance of oilseed rape to V. longisporum was investigated. white rust (1.39), Sclerotinia twigs infection (1.90) and 2006). The plants were analyzed from 2 days before until 11 days after treatment or up to a plant age of 23 days.The results are interpreted to fit the concept of a “shade adaptation reaction” caused by a herbicidal photosynthesis inhibition. – 45J19 (G1), Rohini (G2), Kranti (G3), Chuutki (G4), Kranti (G5), Alankar (G6), Menthol (G7), Radha (G8), Punch (G9) and Nath Sona 212 (G10) – were tested. The supernatant (crude extract) was used for in vitro ATP-S assays. We first homogenized 300 mg fresh leaf samples in sulphosalicylic acid. or rai (Brassica juncea) is the major oil source. All rights reserved. B. juncea . Plants have developed complex mechanisms against the salinity such as osmotic adjustment that is usually accomplished by uptake of inorganic ions as well as the accumulation of compatible solutes (osmoprotectants) and they have been proven to be helpful in the activity of enzymes in plants (Greenway and Munns 1980; Grumet et al. yellow sarson), and Group IV: (B. rapa var. was conducted on the integrated management of major At maturity 9% of ¹⁴ C fixed at anthesis had been mobilized into reproductive organs.

(2006) on Chl concentration and Lakshmi et al. The leaves, seeds, and stems of this mustard variety are edible. With the growing demands, the global oilseed rape production is rapidly increasing since the last 40 years. causing substantial yield loss. Figure 3. observe their role in augmenting the seed yield and its Salt stress increased MDA and Na content while it decreased Chl, N and K content and K/Na ratio, Chl content, NR and ATP-S activities in all genotypes. The homogenate was strained through gauze and centrifuged at 20,000 g for 10 min at 4 °C. In spite of intensive research on V. longisporum in the last decades, some basic knowledge on epidemiology, seed transmission and resistance mechanisms are still lacking. Malibari et al. The data revealed that the adverse effect of NaCl on SL plant−1, A leaf−1, LAI, FW and DW plant−1 was found minimum in genotype G8 (Figures 1 and 2). A similar result has been reported by Meloni et al. Penelitian ini menggunakan rancangan acak lengkap (RAL) yang terdiri dari 4 perlakuan konsentrasi, Abstract Indian mustard, Brassica juncea (Linn.) The effect of treatments and their interactions with genotype on most of the parameters studied at 55 and 65 DAS as also genotype variation were found to be significant (Table 1 and Table 2, Figures 1–7). Figure 2. This variation might be due to genetic make-up of Brassica juncea genotypes. Brassica. We infer that Pro and GB accumulation in G8 might have a role in its salt tolerance. The NaCl caused a significant depression on all the Brassica juncea L. Czern & Coss. The form and typical size of a mosaic virus of Brassica nigra have been ascertained by means of the electron microscope. This study was used a completely randomized design consisting of 4 treatments of kirinyuh leaf extract concentration, namely K0 (control) = 0 g / L water, K1 = 100 g / L water, K2 = 200 g / L water, and K3 = 300 g / L water.
