| Abstract/Contents: | "Several of the management practices applied to amenity turf may lead to its lowered resistance to physiological winter injury. This is especially so in severe winter climates such as those in parts of northern North America and northern Europe. Grass species and cultivars of the grasses which are not bred for, or are ill-adapted to these conditions, may suffer severe physiological injury and also disease caused by low-temperature-tolerant fungal pathogens (snow moulds). the inherent physiological characteristics and state of progress to growth quiescence of a grass determine acclimation for successful overwintering. Some of the physical and physiological factors leading to the induction of grass 'hardening' (acclimation) and 'dehardening' are considered. Plant nutrition, the differential cold hardiness of plant tissues, the stage of grass development, freezing and desiccation, snow covers, ice and ice-water injury, frost-heaving and the relative winter-hardiness of turf grasses in irrigated and dryland turf, winter damage caused by birds and animals are considered in relation to physiological and mechanical turf injury. Environmental and management factors assisting in the practical diagnosis of the causes of winter injury in general, and in relation to specific types of injury and their alleviation are considered. Illustrations of some types of physiological winter injury and a full reference list are included." |
