    EFFECT OF DIFFERENT LEVELS OF LIGHT INTENSrTY ON MORPHOPHYSIOLOGY AND YIELD OF BRINJAL (Solanum melongena L.)
    (Sher-e-Bangia Agricultural University Research System (SAURES), 2020-07) Kabir, M.; Hossain, M.F.; Hasanuzzaman, M.; Habib, Z.F.B.; Mahmud, J.A.
    Low light stress i, a limiting factor tor crop production especially In agroforestry system. A POI experiment was conducted at Shcr-e-Bungla Agricultural University. Dhaka- 1207. dunng the month ...of October 2019 to mid April 2020. Three brinjal varieties viz. VI (OARI Begun-I), V. (BARl Begun-I). V, (BARI Begun-v) were CXP(h~-d to four light intensity (100.75.50 and 2500 I'AR which indicate control SI. S: and S, respccuvely) to evaluate their performances, Light ~trc,~ (rnarnly S: and S,) sub tantially hampered the plant growth, development :I:. well as yield. Low lIght 'tre~. primarily reduced the phorosymhcuc performance of plants which contribute in reduction of plant heIght. number of primary branches and leaves of all bnnjal plants. Moreover low light intensity negatively affects the fresh and dry weight. It also decreased number of fruits, fruit length. fruit diameter and indiv idual fruit weight in nil variety. A~ a result plant wise brinjol production hampered seriously with lull' yield. In comparison with control (100% PAR) rrcannent. 75% PAR condition (S,) decreased fruit weight by 16.8. 13.5 and 19.7~. in V,. V~ and V] respectively. In 50% PAR condition. yield per plant were decreased by 36.·t_ 33.5 and 42.4% in VI_ "1 and V, respectively. Lastly severe stress (S]) decreased fruit weight per plant by 55.0. 61.5 and 67.0% in VI. "1 and V, respectively. From this result it i~clear lhot under severe Stress (S,) V, perform well but V1perform well against $1 and S: treatments.

    RELATIVE TOLERANCE AND PHYTOREMEDIATION CAPACITY OF DIFFERENT Brassica species UNDER LEAD STRESS
    (Sher-e-Bangia Agricultural University Research System (SAURES), 2020-07) Mahmud, J.A.; Mahmud, S.M.A.; Kabir, M.
    The present study was carried out to investigate the metal accumulation and tolerance abilities of five Brassica species (B. compestris. B. napus. B.jllllcea, R. sativus and B. oleracea) seedlings exposed 10 four levels of lead (Pb) stress [0 mM. 0.25 mM. 0.5 rru'vland I mM Pb(NO,):) for six weeks. Of the Brassica species studied, Bi juncea accumulated the highest amount of Pb in a dose-dependent manner and in every casco the Pb coruent was higher in the roots than the shoots. Lead toxicity causes a severe impact on plant growth and biomass. All level of Pb stress reduced seedlings height fresh weight and dry weight in each varieties at 2. -'I and 6 weeks of age. In addition, leaf relative water content and SPAD value were also decreased with increase of stress concentration. But among the varieties, B. juncea showed lowe>! reduction of abovementioned parameters. Considering the growth and physiological performance B juncea is relatively tolerant species though il accumulated highest Pb in rOOIS and ShOOLS.So. B. junceo might be used as a 1001 of phytoremcdiation ill Pb polluted soil.
