Context Wheat (Triticum aestivum L.) adaptation is highly dependent on crop lifecycle duration, particularly the time at which flowering occurs in a specific environment. Frost, low solar radiation, heat and drought can significantly reduce yield if flowers too early or late. genotypes have different durations determined by plant responses to temperature (thermal accumulation vernalisation) photoperiod. These are largely controlled five phenology genes (two PPD1 three VRN1 genes). Advances...
Accurate assessment of plant development is essential for agronomic management and scientific research, crop scales with repeatable reproducible protocols are required to achieve this. Development currently in use ambiguous, subjective qualitative, they do not describe all stages a crop's lifecycle, explicitly distinguish between culm-level crop-level development, incompatible modern analytical computational technologies. Here we propose two new wheat barley development: the Single Culm...
Flowering time of wheat (Triticum aestivum L.) is a critical determinant grain yield. Frost, drought and heat stresses from either overly early or late flowering can inflict significant yield penalties. The ability to predict different sowing dates for diverse cultivars across environments in Australia important maintaining as autumn rainfall events become less reliable. However, currently there are no models that accurately do this when new released. Two major Photoperiod1 three...
The relative time to maturity of grain crops is an important consideration for producers, yet there are no universally accepted classification schemes cultivar phenology guide decisions on variety selection and sowing. A first edition industry wheat was recently developed use across Australia, representing a significant step forward the grains industry. aim this paper revise extend make it more robust, agronomically functional meaningful Australian Cereal Phenology Classification (ACPC)...
A single measurement is useful for determining how far a crop has progressed through grain development, and whether it reached physiological maturity. Grain development commonly assessed by using subjective, qualitative methods that describe the look feel of kernel or colour straw. Physiological maturity in cereal crops can be determined more accurately moisture content; however, content whole spikes potentially quicker easier to assess than individual kernels, with greater degree accuracy....
