Altogether 27 species and hybrids from a rhodological collection and wild populations showed obvious relationships between taxonomic allocation and amounts of ascorbic acid in mature hips.
In the present paper morphological features of hybrids from crossing of four species ofRosa sect.Caninae (R. canina L.,R. zalana Wiesb.,R. rubiginosa L. andR. sherardii Davies) withR. rugosa Thumbg.… (More)
The germination of the pollen from11 individuals of six wildRosa species was studied. The presence of calcium resulted in increased pollen germination, longer pollen tubes, and in a decrease of the… (More)
Morphological and physiological quality of the pollen was studied in fourRosa species growing in habitats with different calcium carbonate content. In soils rich in calcium the pollen showes in all… (More)
During 1977 to 1980 the course of flowering and pollen quality were investigated inSalix cinerea, S. fragilis, andS. pentandra, the dominant woody species in a wetland area called “Mokré louky” near… (More)
Comparison of growth rates ofSalix cinerea andS. pentandra seedlings in terrestric, limosal, and littoral ecophases showed different life strategies of juvenile stages of these willows. Several… (More)
