Natural 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 کاملSeed trait changes in dispersers' guts and consequences for germination and seedling growth.
The effectiveness of a frugivore as a disperser of a plant is greatly determined by how fruits and seeds are handled in its mouth and its digestive tract. Although a number of studies have investigated the effect of avian ingestion on germination, we still know very little about the modifications to seeds during ingestion and the specific consequences on plant fitness. Here we investigate for t...

متن کاملInheritance 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 کاملSeed Priming Increases Germination and Seedling Quality in Antirrhinum, Dahlia, Impatiens, Salvia and Zinnia Seeds
This study was carried out to investigate the effect of hydropriming on seed germination and seedling growth of five different flower seed species (Antirrhinum, Dahlia, Impatiens, Salvia and Zinnia). Hydropriming (20oC, 24 h), surface dried or dried back afterwards, was found to increase germination percentage, seedling emergence and fresh and dry weight. In all species, the maximum advantage i...
