Funkcionalna diploidizacija i prirodna i usmerena evolucija drveća

Abstract

Znanja o drveću početkom XXI veka ne mogu se porediti sa onima početkom 50-tih godina HH veka. Drveće se odlikuje dugovečnošću, adaptivnošću, velikom promenljivošću, veoma složenom organizacijom, ne samo morfološkom anatomskom i fiziološkom, već i na genetičkom nivou. U radu se razmatra uloga funkcionalne diploidizacije drvenastih poliploida na genetičku organizaciju sadašnjih diploida (sekundarnih, tercijarnih i kvaternih). Proces diploidizacije ima ogroman evolucioni i tehnološki potencijal.

The knowledge of trees at the beginning of the 21st century cannot be compared to that in the early fifties of the 20th century. Trees are characterized by longevity, adaptation, high variability, very complex organization, not only morphological, anatomical, physiological, but also at the genetic level. The effect of functional diploidisation of woody polyploids on genetic organization of actual diploids (secondary, tertiary and quaternary) has been dealt with. The process of diploidisation has a huge evolution and technological potential.
