Formation of the phenotypic structure of Phytophthora infestans population in Poland during 1987-2001

open access: yesActa Agrobotanica, 2013
The formation of phenotypic structure of P.infestans population in Poland was determined by analyzing 1603 isolates collected from 1987 to 2001. The race complexity, low at the beginning of experiment, has been increasing from year to year and reached ...

Measuring Fluorescence as a Means to Evaluate the Physiological Reaction to Growth Retardant Applied to Manage Turf

open access: yesAgronomy, 2022
This paper presents the effects of the physiological reaction of the main cool-season grass species used for turf in a temperate climate: perennial ryegrass, Kentucky bluegrass, and tall fescue, on a twice-a-year trinexapac-ethyl (TE) application in late

Snow mould prevalence on perennial ryegrass (Lolim perenne L.) in relation to the light conditions and intensity of turf maintenance

open access: yesActa Agrobotanica, 2012
Effect of shade, nutrition, height of mowing and density of turf on snow mould (Microdochium nivale) prevalence on Lolium perenne under turf maintenance were studied in 2000-2004 at Radzików (central Poland). The materials for studies were cultivars of L.

Water stress-induced changes in morphology and anatomy of flag leaf of spring wheat

open access: yesActa Societatis Botanicorum Poloniae, 2014
Flag leaves of wheat (drought hardened and non-hardened) were examined by light microscopy to determine whether the differences in leaf anatomy could be related to the known differences in dehydration tolerance.

The Circulation in Cold Acclimatization [PDF]

open access: yesCirculation, 1954
The hand and forearm blood flow of the Eskimo has been found to be greater than that of a control group of white persons in a temperate climate both at rest at an ambient temperature of 20 C. and during acute cold exposure. Under cold stress, rectal temperature was better maintained in the Eskimos, though certain deep muscle temperatures fell more than

Plant regeneration from hypocotyl protoplasts of winter oilseed rape (Brassica napus L.)

open access: yesActa Societatis Botanicorum Poloniae, 2014
Protoplasts were isolated from hypocotyls of six breeding lines and two cultivars of winter oilseed rape (B. napus L.). Under presented culture conditions almost all of the protoplasts regenerated cell walls.
