There is great evidence regarding the beneficial influence of rose hips on human and animal health. In this respect, fruits of native populations of Rosa spp. collected from the northeastern part of Romania (400-1060 m altitude) were assayed for nutritional and some morphological properties, in order to select the best genotypes. The results show a great quantitative variability of analyzed genotypes, regarding dimensions and biochemical indicators as follow: ascorbic acid: 866.91 mg/100 g fw (R. rubiginosa), 615.98 mg/100 g fw (R. caesia); carotenes: 34.95 mg/100 g fw (R. subcanina), 24.64 mg/100 g fw (R. nitidula); protein content: 0.47 g/100 g fw (R. micrantha), 0.25 g/100 g fw (R. caesia); total sugars: 17.63 g/100 g fw (R. andegavensis), 11.55 g/100 g fw (R. caryophyllacea). The fruits length, width and dry weight were: 25 mm (R. canina), 12 mm (R. micrantha), 16.5 mm (R. corymbifera), 8 mm (R. micrantha) and 25% dry weight (R. rubiginosa), 38% dry weight (R. nitidula), respectively. The present study demonstrates the existence of a rich rose germplasm source in north-east area, with good biotechnological fruit quality, which recommends them as functional foods according to their chemical contents (R. rubiginosa, R. vosagiaca, R. subcanina, R. canina and R. caryophyllacea) and also as sources for natural colorants in food technology.
The somatic chromosomes and karyotype traits of three Romanian genotypes (coded as CB-1, S-16, L-4) of Hippophae rhamnoides L. have been studied. Diploid chromosome number is 2n=24. The karyomorphological data show that the complements have small chromosomes (1.33 ± 0.014 -2.80±0.01 µm, for CB-1 genotype; 1.13 ± 0.029 -2.90 ± 0.029 µm, for S-16; 1.15 ± 0.099 -2.88 ± 0.024 µm, for L-4 genotype) and the length of haploid complements is 23.97 µm, for CB-1, 22.20 µm, for S-16, 21.73 µm, for L-4. In CB-1 and S-16 male genotypes, the putative Y-chromosome has larger sizes than X-chromosome and it is of metacentric type (CI = 45.77, r = 1.18, for CB-1; CI = 46.22, r = 1.15, for S-16). The L-4 female karyotype is constituted by twelve pairs of morphologically similar chromosomes. The karyotype formulae are 2n = 24 = 13m + 11sm (putative male: 22 + XY), for CB-1 genotype, 2n = 24 = 18m + 6sm (putative male: 22 + XY), for S-16 genotype, respectively 2n = 24 = 22m + 2sm (L-4 genotype, considered as female: 22 + XX). The small size of chromosomes (< 3µm), the presence of only two morphometric chromosome types and preponderance of metacentrics confer a relatively high degree of symmetry to the studied karyotypes. Our results show a low intraspecifi c karyotype variation.
-Inocutis tamaricis is a lignicolous basidiomycete associated exclusively with Tamarix species. The fi rst Romanian record of this species is reported from Constanţa city near the Black Sea coast where it was detected on Tamarix tetrandra. We noticed that in pure culture it forms swollen hyphae in the aerial mycelium, which have not been reported so far for I. tamaricis.
Erysiphe corylacearum, a species of powdery mildew that parasitizes on Corylus spp., has been detected for the first time in Romania. Shortly after the first European record of this pathogen from Ukraine, it was found in many locations throughout the Romanian Carpathians. Disease symptoms on Corylus avellana, morphological characteristics and molecular data (rDNA internal transcribed spacer region) of this pathogen are provided.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
