GENERATIVE PROPAGATION OF SELECTED TERRESTRIALS ORCHIDS OF METHOD IN VITRO
 KYNCL, Jiří
We studied asymbiotic and symbiotic propagation of terrestrial orchids. There wasn´t found statistical effect of organic nitrogen in the form of pepton for examined species of orchid in the asymbiotic propagation. There wasn?t confirmed the positive effect of microelements and addition of carbohydrates (sucrose, glukose and maltose) on the germination of Habenaria dentata. Effects of various iron salts weren´t striking to stimulate seed of Cypripedium calceolus. The effect of different isolates of mycorrhizal fungi in the symbiotic propagation wasn´t statistically proven on investigated species of orchids. The effect of examined substrates (Akadama, volcanic sand and substrate Lukscheiter Orchid) wasn´t statistically confirmed on growth of species Spiranthes odorata and Bletilla striata, when seedling of them were moved to ex vitro conditions.

Seed of field`s produce from today`s look
 RATAJOVÁ, Alena
Annotation This diploma work is focused on multiplication and production of the grass seed and clovers. There is a sum of factors influencing succesful production of the seed. Main objective of my diploma work is focuse on just one of those factors which is appearance of the weed in multiplication area, problems of its cleaning and influence on quality of the seed. Nowadays is seed production very important. After the entry to EU there was a massive decline of dairy herds whereas beef cattle becoming more and more important and influencing pasture programs. Subsidy which is going into program for this kind of usage of agricultural land are very interesting. Essential for succesful use of this subsidy is always usage of certified seed of grass mixtures or its componets.
