Abstract
Ca2+ and calmodulin antagonist [trifluoperazine(TFP), N-(6-aminohexyl-chloro-1-naphthalene sulfonamide (W7)] pretreatments were conducted on two eggplant varieties Nongyouqie and Ermingqie, which have different heat resistance. The results showed that under 40℃(day/night), Ca2+ immersion pretreatment enabled the eggplant seedlings to keep relatively higher activities of superoxide dismutase(SOD) and peroxidase(POD), reduced the production rate of superoxide anion O-2 and the content of malondialdehyde(MDA), alleviated the damage of reduced glutathione(GSH) and the accumulation of proline (Pro), whereas calmodulin antagonist TFP and W7 immersion pretreatments could lead to more rapid loss of SOD and POD activities, increase the contents of MDA, Pro andproduction rate of O-2, aggravate the damage of GSH. Under the same stress condition, heat-resistantvariety Nongyouqie was less injured compared to the heatsensitive variety Erminqie. These data indicated that Ca2+-CaM signal transduction system might regulate the heat resistance of eggplant seedlings by controlling the activity of some antioxidant enzymes and the contents of antioxidant substance.
