medicago spp. is the most important forage crop in many regions of the world.annual medics have distinct advantages over perennial medicago. these species have fastergrowth rate in cultivation year, higher crude protein percentage, tolerance to pests and morevigorous seedlings. morphological and physical aspects of pod and seeds of annual medicsplay a major role in the tolerance of the plants t...

In Elliptio complanatus lateral cilia, two distinct patterns of filament termination can be discerned. In one case, all nine filaments are present and all are single; in the second, at least one filament is missing but doublets are still present. These probably represent different configurations within one cilium in different stroke positions; to get from one to the other, some peripheral filam...

In the present paper, to begin with, the attention is focused on a number of basic characteristics of the configurations. These characteristics concern such morphological aspects as ‘curviance’ and ‘connectivity’. The term ‘curviance’ means the ‘way in which a configuration is curved’ and the term ‘connectivity’ means the ‘way in which the components of a configuration are interrelated’. The mo...
