Hodnocení vzájemného synergismu u fytoplazmy ESFY a viru šarky švestky (PPV) u vybraných peckovin
Vašková, Barbora
The present work deals with problems of synergic effect which may arise between phytoplasma ESFY and potyvirus PPV. Both diseases are globally widespread and extremely dangerous. When infected the plants show infection signs followed by dying. In this paper we deal with the effects of these diseases on apricot a peach trees. Major part of the apricot tree poplulation in the Czech Republic are overmature, and thus inclined to developing uncontrolled infections.

Studium složení kultivačních médií pro množení odrůd meruněk metodou in vitro
Kadlecová, Eliška
In vitro reproduction represents a vegetative way of multiplication, in which small disinfected pieces of plant (explants) are cultivated in a nutritious medium in sterile conditions in order to gain whole new plants. This method, also called micropropagation, is often used for research purposes and more and more often for commercial applications too. This work studies nutritious media for apricots. For Prunus armeniaca cultivars best described media are for bud and embryo cultures. Many different media were tested and it was shown that every cultivar of apricot has its own requirements of nutrition and growth regulators. In this work you can find descriptions of many successfuly used media for apricots along with responses of various cultivars to them.
