Two stilbenes, resveratrol and pterostilbene, exhibit antifungal activity against Leptosphaeria maculans, the fungal pathogen responsible for blackleg (stem canker) in canola (Brassica napus). In vitro studies on the effect of these stilbenes on L. maculans mycelial growth and conidia germination showed that pterostilbene is a potent fungicide and sporicide, but resveratrol only exerted minor i...

seeds of nine sugar beet lines: five drought tolerant, two susceptible, and two medium tolerant were washed, sterilised, dried, and sown in water agar medium for germination test. seedling growth characters such as cotyledon fresh weight (cfw), cotyledon dry weight (cdw), root fresh weight (rfw), root dry weight (rdw), and root length (rl) were determined after the end of 28 days period of expe...

This study was conducted on two canola (Brassica napus) cultivars, Okapi a winter type and cold tolerant and Rgs003 a spring type and cold sensitive. Seedlings were grown in an environmentally controlled growth room with 16 h d-1 photoperiod at 22/16 °C (day/night, control). At the 4-leaf stage, half of pots were transferred to a cold growth room for 7 d at 10/3°C (day/night, cold treatment) an...

almond is among some of the most important nut crops requiring improvement in many aspects of its production. to do that, the first step is an evaluation of the genetic diversity of the existing germplasm. towards this end, 56 vigorous almond seedlings were evaluated with recording eight morphological characteristics (trunk diameter, height of main trunk, canopy density, canopy angle, branch nu...

cabbage aphid (brevicoryne brassicae l.) is a important pest of canola (brassica napus l.) throughout the world, and as the host plant resistance is considered as a useful method to control the pest, therefore twenty one genotypes of canola were evaluated from the view point of their resistance to cabbage aphid infestation in a randomized complete block design with three replications and under ...

melon (cucumismelo) production is significantly affected by fusarium wilt worldwide. the pathogen, fusariumoxysporum f. sp. melonis race 1 (fom1) causes serious economic losses in iran. to find resistance sources of melon, 45 local genotypes and breeding lines, collected from different parts of iran, were screened against race 1 of fom. seedlings were inoculated with a suspension of 1×106 conid...
