heat damage

Catalogue: GRDC Media
Western Australian research has shown that canola is most vulnerable to heat damage at flowering and early pod fill stages, and that high temperatures can halve the yield potential of some varieties... Unseasonably hot weather has reduced the yield potential of many WA canola crops in recent seasons, and some cropping areas this year experienced record temperatures exceeding 34 C in early September... Dr Chen says the information could be used by growers to help them adjust sowing times and select varieties to minimise the risk of yield losses...

Harvesting starts as early as September in Central Queensland and can be as late as December on the Eastern Downs... Where grain drying facilities are available, harvesting can start well before the crop dries down to the required 12.5% moisture and so reduce the time the crop has to stand at risk from weather damage in the field... Reduced grain and flour yield (loss of profitability) has little effect on end product quality (excluding low density due to frost and heat stress damage)...

Spread of flowering dates of dry sown crops can be successfully achieved through varietal choice and adjusting sowing order of the wet sown crop according to the flowering prediction of the dry sown crop... The aim of this paper is to discuss possibility of using varietal differences in phenology mechanisms to achieve a desired spread of flowering dates after dry sowing... The data were used to estimate: 1) spread for flowering dates of varieties across germination dates, 2) the range of achievable variation through varieties for given sowing dates...
