Drought stress is a crucial factor that affects plant growth and development. Reposition of reactive oxygen species (ROS) is one of the biochemical changes happening when plants are exposed to stress. Plants use enzymatic antioxidant defense mechanisms to remove ROS. In the current study, variations of antioxidant enzymes were measured in leaves and stolons of licorice plants (Glycyrrhiza glabra) growing under normal and drought conditions. Samples were harvested at 2, 16, 26 and 28 days after drought imposition treatment. These samples assigned to three drought treatments, without stress (S2), moderate stress (S16) and severe stress (S26 and S28). In comparison with control samples, superoxide dismutase (SOD), ascorbate peroxidase (APX) and peroxidase (POD) activities were up regulated by moderate and severe drought stress in leaves and stolons. The maximum activities of these enzymes were detected in severe stress. Catalase (CAT) and glutathione reductase (GR) activities were decreased in all stressed samples. The increased activities of SOD, APX and POD in severe stress indicated the important role of these enzymes in protecting licorice plants against oxidative stress.

The effect of potent mutagenic chemicals, ethylmethane sulphonate (EMS), sodium azide (SA) and hydrazine hydrate (HZ), on two varieties, namely Avrodhi and BG- 256 of chickpea has been described in relation to chlorophyll and morphological mutations induced in the M2 generation. The frequency of mutations in terms of total plant basis was found to be higher at a lower concentration and concomitantly decreased with the increasing concentrations of EMS, whereas in SA and HZ it does not show any definite trend. Spectrum of chlorophyll mutations included xantha type followed by chlorina type, which outnumbered other types, namely albino, tigrina, and viridis in both the varieties, whereas the morphological mutants include changes for plant height, growth habit, foliage, pod and seed size, flowers, flowering, and maturity period. Frequency of mutations on variety basis indicated that both varieties were found to respond to the mutagenic treatments differently and on mutagen basis show relative specificity. The mutagenized population provides invaluable material for selecting types with the ideal combination of desirable features.

The traditional medicinal Ammi visnaga L. plants can be considered as an important economic source of raw materials for the drug industry. Nowadays, increasing the drug raw materials by using safe and favourable treatments is an important issue. So searching for the proper concentration of the suitable bioregulators which achieving high growth rate and enhancing chemical constituents of A. visnaga plants is the goal of this investigation. Foliar application of different concentrations of eitheramino acids (tyrosine and phenylalanine) and phenolic acids (trans-cinnamic acid, benzoic acid and salicylic acid) displayed significant positive effects on the accumulation of chemical constituents including phenolic compounds, flavonoids and total furanochromones in A. visnaga L. Moreover, the high-performance liquid chromatography analysis showed that some phenolic acids are highly increased, decreased or disappear in A. visnaga plants treated with various concentrations of amino acids and phenolic compounds as being compared with untreated control plants. Ferulic acid, cinnamic acid, coumaric acid and P-hydroxy benzoic acid are the most dominant phenolics in Ammi plants. Phenolics are more effective in stimulating the accumulation of phenols, flavonoids, chromones and consequently the scavenging capacity compared with the investigated aromatic amino acids. Such stimulatory effects are positively related to the applied investigated concentrations of the applied bioregulators. Indeed, Ammi plants treated with phenolics particularly benzoic acid (20 mg L−1) exhibited the greatest accumulated levels of phenolics and chromones there by enhancing thee conomic source of raw materials for drug industry.

The toxicity of a widely used herbicide Roundup, which contains the active ingredient glyphosate, on sweet corn (Zea mays) was investigated. After the determination of EC50 value for root growth, three different concentrations as low (4 ml/L), medium (8 ml/L) and high dose (16 ml/L) were applied to plant samples for 48 and 72 h. At the end of the application period, samples were comparatively studied in terms of their root and leaf anatomy, the upper and lower surface of leaf stomata indexes as well as chlorophyll contents to obtain morphological and anatomical information. Each concentration of glyphosate caused severe toxic effects on Zea mays cells and the strongest toxic effect was observed at the concentration level of 16 ml/L. At the end of the application procedure, the measurements of the parts of the Z.mays root treated with Roundup, the upper and lower surface of leaf stomata indexes, chlorophyll and total carotenoid concentrations were determined in root apical meristematic cells by using squashing techniques.

The present study describes an efficient, rapid clonal propagation protocol for a natural sweetener herb, Stevia rebaudiana. Shoot tips and nodal segments were inoculated on Murashige and Skoog’s medium [MS 1962] containing different cytokinin and auxin alone or in combinations. Shoot tips were proved to be better in comparison to nodal segments having higher rate of shoot induction and multiplication. Best shoot multiplication from both the explants was obtained on MS medium supplemented with 5.0 µM 6benzyladenine (BA) and 1.0 µM a-naphthalene acetic acid (NAA). A maximum of 19.60 shoots per shoot tip and 16.00 shoots per nodal segment with an average shoot length of 4.70 and 4.28 cm were obtained. Subculturing of the regenerating tissue on the optimized treatment showed further enhancement in shoot proliferation without any decline in multiplication rate. The regenerated microshoots showed the most efficient rooting on half strength MS medium augmented with 2.5 µM indole-3-butyric acid (IBA). Plantlets went through a hardening phase prior to ex vitro transfer and established in earthen pots containing garden soil and green manure (1:1). The established plantlets were uniform and identical to mother plant with respect to growth characteristics and vegetative morphology.

Cymbopogon flexuosus (Steud.) Wats. (lemongrass) essential oil (EO) is valued for its aromatic and medicinal properties as it holds an important share among volatile oils traded worldwide and exhibits massive diversity in commercial and consumer utility. The last decade witnessed several pot experiments to test the ability of radiation-processed sodium alginate as a plant growth elicitor. Therefore, the present work was designed to authenticate the pot experiment findings and the study was carried out in the field (30 × 30 m2), according to the simple randomised block design at Agricultural Farm, Aligarh Muslim University, Aligarh, UP (India). Different foliar concentrations of irradiated sodium alginate (ISA; 0 (control), 40, 60, 80 and 100 mg L–1) were applied to scrutinise the performance of lemongrass with regard to ISA under field conditions. The effect of ISA, at a given concentration range of 40–100 mg L–1, was found significant in terms of growth, physiological and biochemical as well as quality attributes. However, ISA-60 mg L–1 proved most favourable and substantially enhanced the activities of carbonic anhydrase and nitrate reductase by 18.4 and 15.1%, respectively and chlorophyll fluorescence by 12.8% in comparison to control. Further, due to applied treatment, the content and yield of EO was increased by 35.6 and 91.4%, respectively, over control. Moreover, citral yield was also enriched by 90.4% over control due to ISA applied at 60 mg L–1.

One field experiment was conducted according to simple randomised block design on mustard (Brassica juncea L.) Var. Varuna to establish the most suitable concentration for soaking of mustard seeds in thiamine hydrochloride solutions of concentrations, that is, 0.01, 0.02, 0.03, 0.06, 0.09 and 0.12% on the performance of mustard. The parameters such as plant dry weight, leaf area, leaf area index (LAI), crop growth rate (CGR), relative growth rate (RGR) and net assimilation rate (NAR) were calculated from 40 to 120 days after sowing (DAS). Yield and its components such as number of pods per plant, 1000 seed weight, yield; biological yield, harvest index and oil yield were measured at harvest. In general soaking of seeds in 0.03% of thiamine hydrochloride solution was found to be the best in comparison to any other concentration of the treatment for most of the parameter studied. In growth parameters, leaf area, plant dry weight showed significant results at the early stages of sampling (that is, 40–80 DAS). CGR also followed the same trend; however, RGR and NAR did not follow the same at any stage of the sampling. Yield parameters like the pod number per plant, biological yield and seed yield as well as oil yield registered significant result. Thus, it was concluded that soaking of mustard seeds in 0.03% thiamine hydrochloride ensured better growth and yield.
