The effect of dry storage was also tested on the effects of germination. The variables tested here are storage at 5 and 20 °C with a control at 0 °C, along with if the seeds were in light or dark conditions at each temperature. Another variable was that at each temperature and light condition, there was a duration of dry storage for the seeds.
The crop is also more sensitive to heat or frost at some stages than others (for example, during the meiosis stage the crop is very sensitive to low temperature). Knowing the growth stage of the crop when checking for problems is essential for deciding which control measures should be followed.
Growing degrees (GDs) is defined as the number of temperature degrees above a certain threshold base temperature, which varies among crop species. The base temperature is that temperature below which plant growth is zero. GDs are calculated each day as maximum temperature plus the minimum temperature divided by 2, minus the base temperature.
Lolium perenne, common name perennial ryegrass, [1] English ryegrass, winter ryegrass, or ray grass, is a grass from the family Poaceae. It is native to Europe, Asia and northern Africa, but is widely cultivated and naturalised around the world. Lolium perenne, showing ligule and ribbed leaf
