Response of Four Strawberry Cultivars to Clopyralid Applied during Fruiting Stage

Evaluation of strawberry cultivars for resistance to Verticillium dahliae Kleb

Verticillium dahlia Kleb. is a soil-borne pathogen which causes worldwide economically important plant and yield losses. So far no resistance preventing the fungus from growing in the plants could be found in the genus Fragaria. But there are cultivars with different levels of tolerance. In particular after the ban on chemical control with effective soil disinfectants (methylbromid) cultivation...

Strawberry Cultivars Vary in their Resistance to Northern Lesion Nematode.

The genetic diversity of commercial cultivars of strawberry Fragaria x ananassa from various parentages, as expressed by their resistance to the northem lesion nematode Pratylenchus penetrans, was evaluated in nematode-infested field plots for two growing seasons. Data taken for each plant in each season included soil nematode Pi and Pf, end-of-season nematode numbers in each entire root system...

Relatively stable response of fruiting stage to warming and cooling relative to other phenological events.

The timing of the fruit-set stage (i.e., start and end of fruit set) is crucial in a plant's life cycle, but its response to temperature change is still unclear. We investigated the timing of seven phenological events, including fruit-set dates during 3 yr for six alpine plants transplanted to warmer (approximately +3.5°C in soils) and cooler (approximately -3.5°C in soils) locations along an a...

Investigation of physiological and biochemical responses of two strawberry cultivars to cold stress

The aim of this study was to investigate the importance of some physiological and biochemical properties related to cold adaptation mechanisms.We aimed to adopt properand efficient indices for identification of winter cold tolerance and susceptibilityin two strawberry cultivars. Differentphysiological and biochemical traits were studied under different cold treatments on the leaf and crown tiss...
