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 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 کاملA chalcone glycoside from the fruits of Sorbus commixta Hedl.
Sorbus commixta Hedl. (Rosaceae) has been traditionally used in oriental countries for the treatment of asthma and other bronchial disorders. In this study, a chalcone glycoside was isolated from the ethyl acetate extract of the fruits of this plant. The compound was identified as neosakuranin based on the spectroscopic analysis and comparison with literature data. This is the first report of i...
متن کاملEffects of TiO2 Nanoparticles on Germination and Primary Growth of Mountain Ash (Sorbus luristanica)
DOR: 98.1000/2383-1251.1398.6.173.11.1.1575.41 Extended Abstract Introduction: Production of nanoparticles and their use are on the rise in different areas of plant science. However, in spite of their increasing production, there is limited information about their effects on plant biology. In the current study, the potential of TiO2 nanoparticles was investigated for the purpose of improv...
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...
