Drought Tolerant

 To investigate the responses of growth and antioxidant enzymes to osmotic stress in two different wheat cultivars, one drought tolerant (Heshangtou, HST) and the other drought sensitive (Longchun 15, LC15), 15-day-old wheat seedlings were exposed to osmotic stress of –0.25, –0.50, and –0.75 MPa for 2 days. It is found that osmotic stress decreased shoot length in both wheat cultivars, whereas to a lesser degree in HST than in LC15. The contents of malondialdehyde (MDA) and the activities of superoxide dismutase (SOD), peroxidase (POD), and catalase (CAT) of shoot in both wheat cultivars were increased by osmotic stress. It is clear that MDA contents increased less in the more drought tolerant cultivar HST than in drought sensitive one LC15. On the contrary, POD and CAT activities increased more in HST than LC15 under osmotic stress. As the activity of SOD, however, no significant differences were found between HST and LC15. These results suggest that wheat cultivar HST has higher activities of antioxidant enzymes such as POD and CAT to cope with oxidative damage caused by osmotic stress compared to sensitive LC15.

Wheat Genotypes

An experiment was conducted to study the screening of wheat (Triticum aestivum L.) genotypes for drought tolerance under laboratory condition during2018 at Department of Seed Science and Technology, College of Agriculture, Vijayapura. The experiment was carried out in a factorial Complete Randomized Block Design with seven treatments replicated three times. Twenty six wheat genotypes were screened for drought tolerance using 0, 15, 30, 60 per cent polyethylene ethylene glycol 6000 (PEG6000) and 1, 2, 5 per cent mannitol solutions. Data were recorded on various seedling parameters like germination percentage, root length, shoot length, seedling dry weight and seedling vigour index. The seedling traits showed a decreasing trend in response to increased concentrations of PEG6000 and mannitol. Wheat genotype DBW-110 (98.70 %) and C-306 (92.50 %) were found to be the best genotype for screened based on germination percentage at 15 per cent PEG6000 and 5 per cent mannitol. Wheat genotypes HI-1620 (6.7 cm) and NIAW-3212 (4.5 cm) produced maximum root length, respectively at higher concentrations of PEG6000 and mannitol. The genotype HI-1620 (6.4 cm, @ 15 %; 5.4 cm, @ 5 % mannitol) showed maximum shoot length. The genotype HD-2733, DBW-14, DBW-88 showed highest reduction of seedling parameters observed at increase in osmotic stress condition.

In order to study the effect of seed hydro priming and magnetic field on tomato seed germination an experiment was conducted in laboratory of Ferdowsi University of Mashhad, Iran, in 2010. The experimental treatments were all combinations of two levels of hydro priming (use of dry seed and soaked seed for five h in distilled water) and eight levels of magnetic field treatments (pretreatment of seeds in 15 mT for 5, 15 and 25 minutes, pretreatment of seeds in 25 mT for 5, 15 and 25 minutes, continuous magnetic field with 3 mT and control) with four replications. Results indicated that hydro priming of seeds reduced mean germination time significantly. Root length increased by 14 percent in seed hydro priming treatment in comparison with dry seed treatment. Shoot length, seedling length and vigor index of hydro primed seeds increased by 7, 12 and 13 percent, respectively compared with dry seeds. Exposure of seeds with 3 mT continuous magnetic field and 25 mT for 5 min increased root length by 29 and 25 percents, respectively in comparison with control. The highest shoot length, seedling length and vigor index were obtained in 3 mT continuous magnetic field and 25 mT for 5 min.

In Ethiopia, wheat productivity is constrained by water stress especially at germination and seedling stage. The objective of this research was to determine the effect of moisture stress on bread wheat (Triticum aestivum) cultivars. Four wheat cultivars (Danda’a, Kubsa, Huluka and Local) were treated with six levels of water stress (0, 50, 100, 150, 200 and 250 g L-1) using PEG-6000. The experiment was arranged factorally in completely randomized design with three replications. Data on germination and growth indices were collected and analyzed using one way ANOVA. The result revealed that highest germination percentage (99.7%), germination rate (14.6 plants day-1) and seedling vigor index (9.67) were obtained from the local cultivar. Progressive increase in water stress had also significantly reduced germination indices. There was no significant difference among the cultivars in producing taller root and shoot length. The local cultivar had significantly produced highest root number (4.3 plant-1), shoot fresh weight (0.214 g), seedling fresh (0.314 g) and dry weight (0.097 g). Even though, all the growth parameters of wheat cultivars showed a diminishing trend with increasing the level of PEG-6000 induced water stress, a highly significant decrease in the parameters were observed starting from 150 g L-1 PEG concentration. Higher shoot length inhibition was observed for Danda’a cultivar followed by Huluka. Huluka’s root growth was more inhibited than Danda’a. According to the growth and germination indices results, the local cultivar is the drought tolerant wheat cultivar. DOI: http://dx.doi.org/10.3329/ijarit.v4i2.22651 Int. J. Agril. Res.

The present study provides an observation and documentation on the effect of static magnetic field on the growth of Triticum aestivum. The seeds are allowed to germinate and the seedlings are grown in an environment of the controlled static magnetic field while other physical factors such as temperature, light exposure, soil pH, etc. are held constant. Also, a comparison of influence on the average height between both the poles of the magnet is estimated and north pole oriented magnet is found to imply a significant difference. Finally some of the potential applications of the study in non-invasive protein silencing, GMO production, Vertical farming and Terraforming are briefly discussed.

Present study was conducted to assess the allelopathic effect of leaf and bark aqueous extracts of Celtis australis on Triticum aestivum, Hordeum vulgare, Brassica rapa, Lens culinaris and Vigna umbellate under In-vitro condition. Different leaf and bark aqueous extracts 5%, 10%, and 15% were used to irrigate the seeds of test crops. The results revealed that the concentration dependent significant (p=0.05) inhibitory effect of aqueous leaf and bark extracts on germination, root and shoot length of all the test crops. Among all the test crops Triticum aestivum was found most sensitive where the germination percentage was reduced down to 46.0% by the leaf extract (15%) as compared to control (82.3%), while the maximum inhibition in the root length of  Lens culinaris (0.5 cm) by 10% leaf extract was observed as compare to control (8.2 cm). In shoot length maximum inhibitory effect was observed in Hordeum vulgare (3.5 cm) as compared to control (13.3 cm). Similarly, the bark extract showed the maximum inhibition in germination percentage of Lens culinaris (41.6%) at 15% concentration as compare to control (70.0%) while the maximum inhibition for the root length was recorded in Triticum aestivum (1.9 cm) at 15% concentration as compare to control (17.3 cm). In shoot length maximum inhibition was observed for Triticum aestivum (1.3 cm) at 10% extract level as compare to control (13.4 cm), while Vigna umbellate (5.5 cm) at 15% concentration showed stimulatory effect as compare to control (3.4 cm) exceptionally. Finally, it is concluded that Vigna umbellate exhibited the maximum tolerance against leaf and bark aqueous and might be a better option for intercropping with C. australis. However, the allelopathic effect on the other test crops can be minimized by removing the fallen leaves from the agricultural fields.
