Induction of Light Sensitive Dormancy in Seed of Lactuca sativa L. (Lettuce) by Patulin.
The antibiotic patiilin (I) has been reported to inhibit seed germination becauise of its toxicity (7). We considered that this butenolide (I) might induce light sensitive dormancy in seeds of lettuce because of its structural similarity to coumarin (II) and ramulosin (III), (see fig 1), which have been demonstrated to possess this biological activity (2,5,6). Possible activitv was tested in th...
متن کاملInheritance of Seed Color in Lactuca Sativa^
The mature fruit of lettuce is an achene or naked seed, the color of which is determined by the color of its pericarp. The pigments that give the seed its particular color seem to be localized in the pericarp tissues.^ The mode of inheritance of seed color is of immediate practical importance to those breeding lettuce for disease resistance, climatic adaptation, and desirable commercial charact...
متن کاملMutants of downy mildew resistance in Lactuca sativa (lettuce).
As part of our investigation of disease resistance in lettuce, we generated mutants that have lost resistance to Bremia lactucae, the casual fungus of downy mildew. Using a rapid and reliable screen, we identified 16 distinct mutants of Latuca sativa that have lost activity of one of four different downy mildew resistance genes (Dm). In all mutants, only a single Dm specificity was affected. Ge...
متن کاملefficiency of different lettuce (lactuca sativa l.) emasculation methods for hybrid seed production
producing hybrid lettuce is prevented by flower structure and usually lead to selfing. based on it, this experiment was carried out to evaluate the performance of different physical and chemical emasculation methods for producing lettuce hybrid seed. a numbers of cultivars with dominant and recessive traits were used as male and female parents, respectively. in the first experiment, physical em...
متن کاملOxidative Phosphorylation in Germinating Lettuce Seeds (Lactuca sativa) during the First Hours of Imbibition.
Experiments with lettuce seeds during the first hours of imbibition showed that oxygen is necessary to sustain high adenine nucleotide ratios and consequently, energy charge values are higher than 0.8 as is usually the case in normally metabolizing tissues.The energy charge value (0.2) of dry seeds soaked in aerated water increased to normal values (0.8) within 30 minutes. The energy charge val...
