説明
Alleviation of high temperature stress in strawberry (Fragaria×ananassa, Duch., cv. Nohime) plants infected with arbuscular mycorrhizal (AM) fungi (Gigaspora margarita, Glomus fasciculatum, Gl. mosseae, Gl. sp. R10, Gl. aggregatum) was observed. During the raising seedling in hot season (July and August in 2002), temperatures in both the greenhouse and soil in the pot fluctuated similarly, and the daily maximum temperature reached over 35°C almost every day. Ten weeks after inoculation, incidence and severity of browning in leaves became lower in AM plants than in non-AM (NAM) ones. Root browning occurred in all plots, however, AM plants had lower severity than NAM ones, especially in Gl. mosseae and Gl. aggregatum plots. AM plants gave greater values in the following parameters : no. of leaves and roots, leaf area, diameter of crown and dry weight of leaves and roots than those in NAM ones; Gl. aggregatum plot showed relatively higher dry weight of leaves and roots than the other species. No characteristic relationship occurred between AM fungal infection level or phosphorus content in plants and alleviation of high temperature stress. These findings suggest that high temperature stress was alleviated in AM fungus-infected strawberry plants and the effect differed with fungal species.
