Hétérogénéité de la Germination des Semences de Rumex crispus mise en Evidence et Essai d'Interprétation.

Germination Heterogeneity of Rumex crispus L. seeds: Occurrence and Attempt at Interpretation. Rumex crispus L. seeds, harvested without taking into account localization of mother plants or seed position on single plants differ in their response to unfavourable conditions inductive of dormancy as a function of their weight. During induction, application of potassium or GA3 prevents or reduces the entry into dormancy, suggesting that the observed heterogeneity is due to nutritional variations of the seeds in relation to their position on the mother plant.
