Biometric and biochemical peculiarities of new M.×giganteus lines with increased ploidy level
Abstract
Aim. The aim of the work was to study biometricl and biochemical traits of new M. × giganteus lines obtained from polyploidization with the use of new antimitotic compounds of dinitroanilines class. Methods. The study has been conducted based on biological and biochemical parameters such as: plant height, number of rhizomes, number of leaves per stalk, ratio of leaves to stems, vegetative mass, dry mass and ash content; total sugars and monosugars content; energy value of biomass. Results. It has been established that all studied lines significantly differed for all biological and biochemical parameters. The best results for majority of parameters has been observed in lines 108 and 202, and namely, vegetative mass of plants, plant height, number of rhizomes and number of leaves per stalk. Conclusions. Some lines of M.×giganteus with increased ploidy level appeared to be significantly superior to triploid forms in most biometric and biochemical parameters and require further study.
Keywords: dinitroanilines, polyploids, Miscanthus × giganteus, biofuel.
