Variation in the loss of seed dormancy during after-ripening of wild and cultivated rice species.

abstract：BACKGROUND AND AIMS:The family Balsaminaceae is essentially herbaceous, except for some woodier species that can be described as 'woody' herbs or small shrubs. The family is nested within the so-called balsaminoid clade of Ericales, including the exclusively woody families Tetrameristaceae and Marcgraviaceae, which is ...
