Modelling the Effect of Temperature on the Germination Speed in Some Legume Crops
Ahmet Balkaya

Abstract:
In this research, the possibility of prediction of germination speeds of the seeds for some legume crops namely, green bean (Oz Ayse 16, Dade, Tina and 4F-89 Cv.), red podded bean (Gitan and Sirik 97 Cv.), pea (Yaprak and Progres No:9 Cv.), cowpea (izmir orij. population and karagoz Cv.) and broad bean (Amasya orij. population) by mathematical models based on temperature was investigated. For this reason, a model (D= a-b*T+c*T2) for predicting the time to emergence in relation to temperature for some vegetable crops was utilized. This model changed to (D= a+b*T-c*T2) for germination speed of the crops tried. The prediction performance of this model with respect to the data used was highly acceptable. Values of regression coefficients (R2) for each crop varied from 0.83 to 0.99 depending on the species. It was found that the new mathematical models obtained after adapting the present data to the above mentioned model could be used safely in predicting germination speed for some legume crops. In addition, optimum temperatures (To=b/2*c) for seed germination speed in the tried crops were calculated by using the coefficients obtained from the produced regression models.
