Webgrowth model of the sorghum development has been an ongoing attempt in several centers at the global levels. Seed germination and seedling establishment We have observed that, there is a drastic mismatch between the germination percentages of the seed planted in the lab condition and field condition. WebExperimentally determined germination curves of microbial spores come in two shapes, sigmoid and nonsigmoid, which can frequently be described by the stretched exponential model. The curve can also be simulated by a stochastic model where the germination probability can vary with time.
