THE USE OF A FLOWERING STABILITY INDEX FOR BIOCUMATIC RESEARCH

Abstract

Finlay and Wilkinson analysis was used to study the stability, over 21 years. of the beginning of flowering of 53 species. This approach allows to study the behaviour of a siegle species in respect to the average behaviour of all species. Twenty-one out of 25 docile species are sensitive, while the remaining 4 are docile (their beginning of flowering time was relatively constant). The 28 recalcitrant species are characterized by unpredictability in Lbe beginning of flowering time.
