The pasture and animal productivity of established high producing pastures in the Waikato has been compared with newly sown pastures based on recently released herbage cultivars. The established pastures were a mixture of Nui perennial ryegrass, Paspalum dilatatum and Htiia white clover. The new cultivars tested were Ellett perennial ryegrass, Wana cocksfoot and Roa tall fescue, each sown with ...
The relationships between testis size, hormone secretion and sperm production were studied during the spring (December) and autumn (May) in rams of two breeds with different breeding seasons and body weights (Corriedale and Australian Merino) maintained on native pastures and under natural photoperiods in Uruguay. Blood samples were collected at 20-min intervals during a 260-360-min period in 1...
in fruit trees damage of frost and freezing is depended to time of chillhng and tree phonological stage. almond (prunus amygdalus b. (and apricot (p. armeniaca l.) cultivars are usually the first fruit trees to bloom and susceptible to damaging frosts in the early spring. a study was conducted on different types of almond and apricot cultivars in order to investigation the main factors related ...
In the present research, for the development of Fars province minimum temperature atlas, minimum daily temperature data of 20 evaporative stations of Fars Regional Water Organization and five synoptic stations of Fars Meteorological Organization were used. At first, two starting times were selected for all of the stations. The first was the first day of Farvardin for analyzing the spring frost ...
Low temperatures in the autumn induce enhanced expression/relative accumulation of several cold-inducible transcripts/proteins with protective functions from Late-embryogenesis-abundant (LEA) superfamily including dehydrins. Several studies dealing plants grown under controlled conditions revealed a correlation (significant quantitative relationship) between dehydrin transcript/protein relative...
The well established phenomenon 0/ seasonality 0/ birth dates (winter excess) and admission dates (summer excess) o/patients with schizophrenia and bipolar disorder was re-examined in a Southern A/rican study 0/ ill-patients. Monthly and seasonal analyses relpectively resulted in a May (late autumn and winter) excess o/schizophrenic male births and a March (late summer and autumn) excess among ...
Winter oilseed rape (Brassica napus) is a global major crop used for the production of vegetable oil. Typically sown in late summer and grown throughout winter spring, it allows interesting cultural practices, such as frost-sensitive intercropping with companion plants. This practice not only provides nitrogen resources much needed by but plants can also prevent weed growth autumn, thereby redu...
Prunus spinosa species is distributed across wide range of geographical areas which are subject to climatic, edaphic factors and long-term divergent selection. This could lead local adaptation hence ecotypes in terms morphological, physiologically or biochemical inclination their environment. To investigate whether the (Prunus spinosa) has been influenced by environmental conditions populations...
