Little seed canary grass (Phalaris minor L.) is a major weed in wheat fields in some parts of Iran. To evaluate the efficacy of molecular and greenhouse methods in detecting the resistance of 49 biotypes of canary grass(Phalaris. Spp) to acetyl-CoA carboxylase-inhibiting herbicides, two methods including whole plant screening and PCR-based molecular methods were applied. Results showed that the...

The present study was aimed to enzymatic antioxidants (superoxide dismutase, catalase, polyphenol oxidase), nonenzymatic (saponin, flavonoids, ascorbic acid and tannin), anti-oxidant ability assays (total anti-oxidant, hydroxyl radical scavenging ability, reducing power activity, inhibition of lipid peroxide formation, DPPH activity metal chelating assay) in I. marginata leaves whole plant. res...

Kandelia candel, a mangrove belonging to the family Rhizophoraceae, whole plant is reported have anti-diabetic properties and was studied for evaluation of in vitro antioxidant antidiabetic study. Total Phenolic Content (TPC), Flavonoid (TFC) Alkaloid were quantitatively estimated by using standard protocols. The study evaluated activity extract method employed are DPPH radical scavenging assay...

Studies were conducted with 9 to 12 day-old soybean (Glycine max [L.] Merr. cv. Williams) seedlings to determine the contribution of roots to whole plant NO(3) (-) reduction. Using an in vivo -NO(3) (-) nitrate reductase (NR) assay (no exogenous NO(3) (-) added to incubation medium) developed for roots, the roots accounted for approximately 30% of whole plant nitrate reductase activity (NRA) of...

The performance of cowpea aphid, Aphis craccivora Koch. (Hemiptera: Aphididae), on five faba bean, Vicia faba L. (Fabales: Fabaceae) cultivars was evaluated. Colony development, biology, and demographic parameters were studied to measure the cowpea aphid performance. Two methods, whole plant and detached leaf, were used in these experiments. After 14 d , the number of apterous adult, nymphs, an...

Lack of data on safety of herbal medicines have endangered human health and life. The present study evaluated the genotoxic and mutagenic effect of Kalanchoe laciniata to access the safety and usefulness of the medicinal plant. Aqua-methanolic and n-hexane extracts of K. laciniata were evaluated for the genotoxic potential using Ames assay and cytotoxicity was evaluated using MTT assay. Ames as...
