Field performance of micropropagated plum cv Požegača

Abstract

Comparative study on flowering, fruit set, cropping, as well as on biological-pomological characteristics of fruit and a leaf surface in plum cv Pozegaca propopagated by micropropagation in vitro (tissue culture -TC) and standardly (standard culture - SC), ie. grafted on Myrobalan (Prunus cerasifera Ehrh.), has been done. Pozegaca TC had higher percentage of fruit set and yield per tree. In addition, a higher fruit and stone mass, coupled with fruit length and width, were recorded with TC plants. The leaf surface was also greater in TC plants. Generally, all the parameters monitored were higher in TC plants, but the difference was not always statistically significant.
