tailieunhanh - NECTARIES AND NECTAR

The evolutionary origins of nectaries and nectar are relatively obscure, but several researchers, working on a broad scale on the evolution of angiosperm families, have provided overviews of nectary incidence, diversity, origin, and function. Two contrasting examples below show how concepts regarding the origin of nectaries and nectar have been modified in the light of new information. Firstly, in his outline of the classification of the angiosperms, Armen Takhtajan (1980) gives a simple, concise statement on the purpose and origin of nectaries:. | Nectaries and Nectar Susan w.
