BY STUDY OF PHENOLICS AND PHENOL OXIDASES IN THE CORM AND BUD TISSUES - 31419 EN Journal Article Investigation into total phenolics and their spectrum in the buds and corms of saffron Crocus and a study of polyphenol oxidase changes in the apical bud during different stages of growth and development showed that changes in the growth and development of the apical bud may be related to changes in the composition of phenolics in the corm. A sudden intense change in content and kind of phenolic components probably acts as a switch.This change shifts the balance between endogenous growth promoters and growth inhibitors so that bud growth is resumed and certain developmental changes in the bud are triggered https://jsciences.ut.ac.ir/article_31419_31fbbf027ddf70f3db56c2382758d9c9.pdf
