“…5) In the present study, nitrogen influenced (increased) the number of spikelets in only two instances; these were at low stress and at 22"C: in both instances there was no furlher increase provided by the Nl74 treatment over the N 1 16 treatment (darta not shown). Robins and Domingo (1962) found no effect of nitrogen on the number of spikelets while a direct relationship was found in an earlier study (Campbell and Davidson 1979b).…”

“…Since soil cultivation and production techniques vary little between seasons for specific production areas, dominant variables appear to be weather conditions. The most critical climatic factors affecting plant yield and grain quality in the Western Cape are those oftemperature and rainfall (Beyers, 1992), Campbell and Davidson (1979) found that the effect of water stress on yield components is related to the time and intensity of the stress. Water stress occurring at kernel set and in combination with high temperatures, resulted in accelerated senescence of leaves, a shortened period for kernel set and a reduction in individual kernel mass (Austin, 1989).…”

“…In contrast, temperature cannot be manipulated in the field, and most of our knowledge is based on results from growth chamber experiments (Wardlaw 1970;Campbell and Davidson 1979;Hunt et al 1991;Wardlaw and Moncur 1995;Baker 1996). Consequently, the effects of moisture stress on growth of wheat under field conditions in Canada (Clarke and McCaig 1982;Clarke et al 1984) are better understood than the effects of high-temperature stress.…”

McCaig, T. N. 1997. Temperature and precipitation effects on durum wheat grown in southern Saskatchewan for fifty years. Can. J. Plant Sci. 77: [215][216][217][218][219][220][221][222][223]. Approximately 60% of Canadian durum wheat (Triticum turgidum L.) is produced in the semi-arid, Brown soil zone of southern Saskatchewan. The Durum Wheat Cooperative Test (DWCT) provides the means of evaluating potential new cultivars, and has been grown at Swift Current, located near the centre of the Brown soil zone in Saskatchewan, for more than 50 yr. Historical yield-related data from the DWCT were analyzed in conjunction with daily precipitation and maximum daily temperature (MaxDT) data with the objective of improving our understanding of the effects of these weather variables on durum wheat grown in this semi-arid region.The highest correlation between the weather variables and grain yield was during the period near the end of June through early July, approximately the time of anthesis. The correlation with kernel number m -2 (KNum) was maximum near the end of June, while the correlation with kernel weight was highest around the third week of July. The maximum effect of these weather factors in limiting yield in the Brown soil zone was through an impact on KNum around anthesis. Hectolitre weight and time-to-maturity appeared to be influenced mainly by the weather in July, while crop height was determined by the weather near the end of June. An analysis which examined cumulative heat-units above threshold MaxDT of 20, 24, 28 and 32°C indicated that temperatures >24°C may be detrimental during early June although high temperatures are less common in June than in July. Yield was also negatively impacted by temperatures >20°C during the first 3 wk of July.Future yield gains in this semi-arid region may be dependent upon the development of cultivars which are more tolerant of drought and high-temperature stress at anthesis.

Effets de la température et des précipitations sur la croissance du blé dur dans le sud de la Saskatchewan au cours des 50 dernières années. Can. J. Plant Sci. 77: 215-223. Quelque 60% des emblavures de blé dur (Triticum turgidum L.) produit au Canada le sont dans la zone semi-aride des sols bruns du sud de la Saskatchewan. L'essai coopératif de variétés de blé dur (ECBD), le moyen actuellement utilisé pour l'évaluation des nouveaux cultivars est notamment conduit depuis plus de 50 ans à Swift Current, ville située presque au centre de la zone des sols bruns de la province. Nous avons analysé les données historiques de rendement obtenues dans le ECBD, en regard des données météorologiques : précipitations et maxima de température (TJMax) journalier, dans le but d'améliorer notre compréhension des effets de ces variables météorologiques sur le blé dur cultivé dans la région. Les plus fortes corrélations entre les variables météorologiques et le rendement en grain étaient observées dans la p...
