For laboratory screening, the effect of different levels of Poly Ethylene Glycol (PEG) concentration viz., -0.2, -0.4, -0.6 and -1.0 MPa on germination, shoot length and root length were studied. There was a considerable decrease in the germination potential among all the genotypes with increase in PEG concentration. The TM 12077 showed higher level of tolerance to PEG induced drought stress showing 30.8 % germination with 3.2 cm and 8.85 cm shoot and root length, respectively at higher level of concentration (1.0 MPa). In the field screening under managed stress condition, TM 12077 and TM 12012 showed higher accumulation of proline (4.15 mg/g). Chlorophyll stability index was more than 80 % in the genotypes TM 12012, TM 12077 and TM 12061. The genotype TM 14035, the varieties Anna (R) 4 and Vandhana matured early in 115 days. Number of tillers per plant, number of panicles/sqm and yield/hectare were maximum in TM 12077. While considering both laboratory and field screening, the genotypes TM 12077, TM 12012 and TM 12061 were found promising for water stress environment and can be utilized as donors in the drought tolerance breeding programs. High heritability coupled with moderate to high GA as per cent of mean recorded for plant height, tillers per plant, chlorophyll stability Index and total chlorophyll content indicates the presence of additive gene effects and their improvement through direct selection.

The study explores the chromium accumulation potential of seven indigenous weeds of Hazaribagh, Bangladesh. It further investigates the threat and toxicity associated with vegetables, crops, and aromatic plant cultivation in chromium-laden soil. The study revealed that the study area contains alarmingly high levels of Cr (III), i.e., 2328–34,536 mg Cr/kg as demonstrated in a spatial GIS map. The weeds accumulated 27.8 – 2496.6 mg Cr/kg and 11.4 –506.9 mg Cr/kg in roots and shoots respectively. Among the seven weeds, Phyllanthus niruri, Cyperus sp., and Vernonia patula met at least one phytoremediation criteria and can be used for soil chromium remediation purposes. In the pot study, five species, Brassica nipus (mustard), Helianthus annuus (sunflower), Ocimum sanctum (holy basil), Capsicum annuum (green chili), and Abelmoschus esculentus (okra), were exposed to chromium (III) sulfate spiked soil for forty days at 100, 500, and 20000 mg Cr/kg soil concentrations. Green chili, sunflower, mustard, and okra demonstrated high chromium uptake in roots (13.3- 195 mg/ kg) and shoots (13.2-63.7 mg/kg) exceeding permissible and toxicity threshold for plants. These findings highlight the importance of not cultivating these species in chromium-contaminated areas. However, basil showed chromium tolerance by limiting the uptake in the shoot along with excellent growth reducing the risk of chromium transferring through the food chain, and therefore, is safe to grow in Hazaribagh for producing metal-free aromatic oil.

The plant growth regulators were added into MS, MS + 2,4-D (1.5 mg/l, 2.5 mg/l, 3.5 mg/L, and 4.5 mg/l) and MS + 2.0 mg/l NAA + 1.0 mg/l ZT, MS + 2.0 mg/l NAA + 1.0 mg/l KT, MS + 2.0 mg/l NAA + 1.0 mg/l 6-BA and MS + 2.0 mg/l NAA. The leaves were treated as broken and cultured on these nine different media types. Results showed significant differences in color, morphology, and callus quantity. In the first medium, the callus of rose leaves was the best on MS + 4.5 mg/l 2,4-D medium, followed by MS + 2.5 mg/l 2,4-D and MS + 3.5 mg/l 2,4-D, and finally MS + 1.5 mg/l 2,4-D. No callus was found in MS medium. In the second kind of medium, the leaves grow callus, and the callus grew best on MS + 2.0 mg/l NAA + 1.0 mg/l ZT medium, followed by MS + 2.0 mg/l NAA + 1.0 mg/l KT, finally MS + 2.0 mg/l NAA + 1.0 mg/l 6-BA, MS + 2.0 mg/l NAA medium, the callus grew loose and dry, and lost luster after a few days. Therefore, 2,4-D, KT, ZT, 6-BA, and NAA can promote the formation of callus. With the increase of concentration of 2,4-D, the callus induction rate increased, and the color of the callus also changed significantly. The combination of KT, ZT, and NAA had an obvious effect on callus induction and expansion. Bangladesh J.
