Applying survival analysis for estimating and comparing flushing time variability

Survival analysis is class of statistical methods for studying the occurrence and timing of many different kinds of events. In this research we applied survival analysis for comparing and estimating flushing times of sixteen protrenances of Penduculate Oak (euercus Robur L.). Flushing time is a very important feature of the physiological character and it is known that later flushing Oak has some good properties that are preserved even when it is grown on non-native sites. The survival analysis showed significant difference in flushing time of sixteen provenances and based on these results some later flushing Oak provenances were determined.
