Labor-saving Preservation of Powdery Mildew of Strawberry by Sterilized Seedling Culture
Various preservation methods at low temperature have been reported for several powdery mildew fungi, but the conidia of Podosphaera aphanis causing powdery mildew of strawberry could not be preserved either at low temperature or by freeze-drying and liquid-drying of conidial suspensions or diseased leaf discs. Here, we developed a new technique for a labor-saving preservation of the conidia of ...
متن کاملPostharvest Physiology of Strawberry Fruits Treated With Sodium Dehydroacetate
Sodium dehydroacetate (NaDHA) was most effective in extending the shelf life of fruits of strawberry cultivars that have the poorest holding capacity. Decreased respiration of treated fruits is attributed to the fungicidal property of NaDHA or inhibitory effect of the chemical on a respiratory enzyme of the fruit. A 0.5% NaDHA solution retarded ripening. Various types of fungicides have been ev...
متن کاملInitiation, development, and survival of cleistothecia of Podosphaera aphanis and their role in the epidemiology of strawberry powdery mildew.
A collection of four clonal isolates of Podosphaera aphanis was heterothallic and was composed of two mutually exclusive mating types. Cleistothecial initials approximately 20 to 30 microm in diameter were observed within 7 to 14 days after pairing of compatible isolates and developed into morphologically mature ascocarps within 4 weeks after initiation on both potted plants maintained in isola...
متن کاملStrawberry Accessions with Reduced Drosophila suzukii Emergence From Fruits
Drosophila suzukii is threatening soft fruit production worldwide due to the females' ability to pierce through the intact skin of ripe fruits and lay eggs inside. Larval consumption and the associated microbial infection cause rapid fruit degradation, thus drastic yield and economic loss. Cultivars that limit the proliferation of flies may be ideal to counter this pest; however, they have not ...
متن کاملAntioxidant effects of strawberry fruits at two phenological stages
Background & Aim: Strawberry (Fragaria vesca L.) is a plant belonging to the Rosaceae family with medicinal properties, including antioxidant activity. The present study aimed at investigating the antioxidant properties of strawberry. Experimental method: To examine the antioxidant effect, fruit extracts at two phonological stages of growth (ripe and unripe strawberry) were prepared. ...
