Inheritance of the chloroplast genome in Sorbus aucuparia L. (Rosaceae).
Chloroplast DNA (cpDNA) inheritance was investigated in Sorbus aucuparia using progenies obtained from six controlled crosses between individuals of known haplotype. Polymerase chain reaction (PCR) amplification, followed by restriction analysis, was used to characterize 248 offspring for either of two polymorphic cpDNA fragments. All offspring exhibited the maternal haplotype, which indicates ...
متن کاملPopulation structure at the S-locus of Sorbus aucuparia L. (Rosaceae: Maloideae).
Low sequence divergence within functional alleles is predicted for the self-incompatibility locus because of strong negative frequency-dependent selection. Nevertheless, sequence variation within functional alleles is essential for current models of the evolution of new mating types. We genotyped the stylar self-incompatibility RNase of 20 Sorbus aucuparia from a population in the Pyrenees moun...
متن کاملNatural Inhibitors of Germination and Growth IV Compounds from Fruit and Seeds of Mountain Ash (Sorbus aucuparia)
Extracts from ripe fruit and seeds of Sorbus aucuparia inhibit germination of other seeds, tested with Amaranthus caudatus and Lepidium sativum. The main compound of the “neutral fraction” of fruit extracts is the lactone compound parasorbic acid (4 —7 mg/g fresh weight) which inhibits germination at concentrations > 5x1C T 4 m. The “acid fraction” contains abscisic acid (1 .3—2.5 ^ / g fresh w...
متن کاملInfluence of Plant Growth Regulators and Media on In vitro Propagation of Sorbus aucuparia L.
Aucuparia is an important slow growth forest tree with medicinal, industrial and ornamental uses which is applied for reforestation in high altitude of mountain lands. This species has been endangered at northern forests of Iran; therefore micropropagation of adult trees by bud culture may help to reforestation. The best sterilizing treatment was the buds washing with HgCl2% 0.1 solution for 7 ...
متن کاملPhenolic extracts from Sorbus aucuparia (L.) and Malus baccata (L.) berries: antioxidant activity and performance in rapeseed oil during frying and storage.
In the present study, phenolic extracts and fractions from Canadian rowanberry (Sorbus aucuparia) and crabapple (Malus baccata) were screened for antioxidant activity using DPPH radical scavenging activity, and β-carotene bleaching assays. Furthermore, rapeseed oil was supplemented with extracts/fractions and performance was assessed during accelerated storage at 65°C, under Rancimat at 120°C, ...
