Erysiphe necator Schwein overwinters in Hungary primarily as large numbers of chasmothecia providing primary inoculum for grapevine (Vitis vinifera L.) infection in the next year. In two field trial...
The incidence of Zucchini yellow mosaic virus (ZYMV) was monitored in the south Moravian region of the Czech Republic during 1997–2001. Crops of gherkin, squash, zucchini and cucumbers were found infe...
Throughout the eastern United States, the spread of the hemlock woolly adelgid, Adelges tsugae Annand, has caused high mortality of eastern hemlocks Tsuga canadensis (L.). We recorded overwintering su...
Antarctic krill (Euphausia superba) were sampled in contrasting habitats: a seasonally ice-covered deep ocean (Lazarev Sea), ice-free shelves at their northern range (South Georgia) and the Antarctic...
Winter survival is variable among commercially grown strawberry (Fragaria x ananassa) cultivars. The main objectives of this study were to evaluate the molecular basis that contribute to this differen...
We tested whether clones ofDaphnia pulexin a mesotrophic lake differ with respect to overwintering strategies:either surviving the winter as parthenogenetic females with reduced metabolism in pelagic ...
The relationship between fructan (fructose polymer) level in early winter and overwintering ability in wheat varieties was studied by using 15 varieties and 14 lines related to pedigree of breeding. 1...
The objective of this study was to clarify the changes in the contents of endogenous carbohydrates and proline in the stolons and leaves of centipedegrass (Eremochloa ophiuroides (Munro) Hack.), durin...

Changes in Nutritive Value of Italian Ryegrass (Lolium multiflorum Lam.) during Overwintering Period.
To estimate the possibility of napiergrass for cultivating as a perennial in southern Kyushu, the overwintering ability, as assessed by the percentage of overwintered plants (POP) in early May, was de...
It has been known that spring wheat sown immediately before continuous snow cover has higher quality and yield than that sown in spring in the heavy snowfall areas of Hokkaido. To increase the stabili...
The new cultivation method of spring wheat sowing before continuous snow cover has many advantages, such as increase of yield and avoidance of scab, but has the flaw of uncertainty of overwintering. ...
Kelp forest communities are critical to the entire marine ecosystem because of their high primary and secondary productivity and their source as food and refuge to a wide variety of organisms. Ner...
