We evaluated three possible functions of clonal growth related to genet persistence in the root-suckering understory tree pawpaw, Asimina triloba (L.) Dunal: (1) risk spreading through multiplication of stems, (2) enhanced establishment and survival of new stems, and (3) horizontal expansion growth of patches. The number, diameter growth, and spatial distribution of annual stem recruits were ex...

sainfoin (onobrychis sativa), a forage legume, is worth attention because of its production and superior quality among pasture and hay forage crops in iran. sainfoin forage yield may be reduced by different levels of salinity. increasing forage yield in saline environments through plant breeding could partially compensate for this shortcoming if sufficient genetic diversity and heritability be ...

this study aimed to investigate morphological changes of capparis deciduas and c. spinosa and their effects on nebkha formation. in order to examine the morphological changes of these plants, nine c. spinosa nebkhas of varying ages were randomly selected and size and number of adventitious roots, number of shoot and buds were counted. results showed that the dead and green parts of c. spinosa i...
