“…10). However, preconditioning of tomato seeds with Ambiol were reported to increase germination percentage by 12.4% [22]. Other literature reports suggests that wheat seed priming with triazolic compounds, hormones and sodium nitroprusside induced an increase in percentage germination [48, 52, 55].…”

“…Tomato seed treatments with Ambiol induced positive effects on germination, growth and seedling development which were passed-on to next generation. Vital parameters like photosynthesis, leaf area, percent germination, root mass and shoot mass were considerably improved in parents as well as in progeny [22].…”
Priming is a valuable, facile and well-established technique used to enhance seed quality to achieve rapid germination, establishment of stress resistance and improvement of crop yields. Different natural and synthetic priming agents have been used for better crop performance and abiotic stress management. In this study, four different benzimidazoles were selected as priming agents and their comparative effects were evaluated on different biochemical attributes including total soluble protein, total oxidant status, MDA contents, antioxidant enzymes (SOD, POD) and hydrolytic enzymes (protease, estrases) compared to control. Treatments with 2-thio-1-
H
-benzimidazole reduced total soluble proteins and increased total oxidant status significantly but no considerable effect was observed on other parameters. Priming with 2-(4-chlorophenyl)-1-
H
-benzimidazole considerably increased the total oxidant status and a little improvement was observed in total soluble proteins. Seeds primed with 1-
H
-benzimidazole showed a noticeable decrease in the protease activity while all other priming treatments were unable to induce any detectable change compared to control. The treatment with 2-(4-methoxyphenyl)-1-
H
-benzimidazole induced maximum reduction in MDA contents and POD activity. Moreover, all benzimidazole priming treatments reduced mean germination time, increased germination percentage and germination rate of wheat seeds.
“…Moreover, seeds preconditioned with Ambiol ® (2‐methyl‐4‐[dimethylaminomethyl]‐5‐hydroxybenzimidazole) has been found to increase seed germination, seedling growth and yield, and improve tolerance to drought and cold stresses of both the parental and the progeny plants (Borsos‐Matovina and Blake , MacDonald et al. ). In general, Ambiol ® (Ambiol Inc., Toronto, Canada) is considered as a plant growth regulator, whose mechanism in modulating plant's response to abiotic stress is similar to ABA (MacDonald et al.…”
Low temperature seriously depresses seed germination and seedling growth in winter wheat (Triticum aestivum L.). In this study, wheat plants were sprayed with abscisic acid (ABA) and fluridone (inhibitor of ABA biosynthesis) at 19 days after anthesis (DAA) and repeated at 26 DAA. The seeds of those plants were harvested, and seed germination and offspring's seedling growth under low temperature were evaluated. The results showed that exogenous ABA application decreased seed weight and slightly reduced seed set and seed number per spike. Under low temperature, seeds from ABA-treated plants showed reduced germination rate, germination index, growth of radicle and coleoptile, amylase activity and depressed starch degradation as compared with seeds from non-ABA-treated plants; however, activities of the antioxidant enzymes in both germinating seeds and seedling were enhanced from those exposed to exogenous ABA, resulting in much lowered malondialdehyde (MDA) and H 2 O 2 concentrations and O À 2 production rate. In addition, the maximum quantum efficiency of photosystem II was also enhanced in ABA-treated offspring's seedlings. It is concluded that exogenous ABA treatment at later grain-filling stage could be an effective approach to improve cold tolerance of the offspring during seed germinating and seedlings establishment in winter wheat.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
