Effect of Water and Temperature on Seed Germination and Emergence as a Seed Hydrothermal Time Model
The physiological process of germination depends on several environmental factors such as temperature, water potential, light, nutrients and smoke. Water and temperature are determinant factors for seed germination. Both factors can, separately or jointly, affect the germination percentage and germination rate. The effect of temperature on germination and water potential on germination canoften...

متن کاملPrediction of emergence of Flixweed (Descurainia sophia) and Wild Oat (Avena fatua) using thermal time models in Winter Rapeseed (Brassica napus)
A thermal time (TT) model was developed to simulate field emergence of two weed species (flixweed and wild oat) in winter rapeseed. Practical predictive weed emergence models can provide information about timing of weed emergence. Non-linear regression models are usually able to accurately predict field emergence under specific environmental conditions. In the present study, cumulative seedling...
متن کاملSeedling emergence response to temperature in safflower: measurements and modeling
Quantitative information about the response of seedling emergence totemperature for safflower (Carthamus tinctorius L.) is rare. The main objective ofthe present study was to develop a model for predicting days to emergence forsafflower as influenced by the temperature. In this regard, a field experiment with arange of sowing dates and four safflower cultivars were conducted to describe theresp...
