متن کاملA . , Buczkowska H . Morphological and chemical characteristics of Rosa fruits
The aim of this study was to evaluate the morphological and chemical parameters, antioxidant activity (DPPH) of five rose species (Rosa rugosa, R. villosa, R. californica, R. spinosissima, and R. × damascene) and grouping them according to the harvest date. On the basis of the study, rose species grown in eastern Poland were grouped according to their harvest time, and three dates of cumulative...
متن کاملThe Worldwide Significance of Karyotypic Variation in Rosa Acicularis (rosaceae)
Evidence is provided which shows that there is a wider variation in karyotypes of Rosa acicularis subspecies seen within their ranges in North America (Rosa acicularis Lindl. subsp. sayi (Schwein.) W.H. Lewis and the Eurasian species (Rosa acicularis Lindl. subsp. acicularis) than was originally presumed. It is proposed that the evolution and distribution of these karyotypes into two distinct s...
متن کاملVolatile oil composition of Rosa damascena Mill. (Rosaceae)
The volatile oil obtained by hydrodistillation of the petals of Rosa damascena Mill. (Rosaceae) was analyzed by gas chromatography and gas chromatography/mass spectrometry (GC/MS). The yield of the oil was 0.12 % (v/w). Fifty compounds representing 99.06 % of the oil were characterized. The volatile oil was found rich in sesquiterpenes and aliphatic components, consisting of two monoterpenic es...
متن کاملTowards a FISH-based karyotype of Rosa L. (Rosaceae)

However, the cytogenetic studies of rose species are scarce and mainly focused on chromosome counting and chromosome morphology-based karyotyping. Due to the small size of the chromosomes and a high frequency of polyploidy in the genus, karyot...
