Depth Controlled Deuteron Irradiation of Lactuca sativa Seeds. II. Energy Loss in the Outer Seed Layers.
In a previous paper (2) the germination and subsequent growth of deuteron-irradiated lettuce seeds was described, with special emphasis on the influence of penetration depth. It was shown that depth of penetration is the predominant factor in eliciting the effects described, i.e., germination percentage and root length are affected at different depth levels. The general phenomena observed in ou...

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...

than those for 100 % curves. Since there exists no non-decreasing functional relationship between germination percentage and energy loss in this region, ionizations in the fruit coat cannot be responsible for the induced germination. Likewise, in the region of the embryo there is a 69 % germination curve which lies above a 100 % curve. (In both of these cases visible embryo damage could be seen...
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...
