Abstract:

The degree of leaflet o rienta tion w as measured for six so ybean cul tiv ars on anhourly basi s f rom 07∶ 0 until 17∶ 0 o f loca l solar time during the V9 and R4 . Measurements w ere taken on 2 separate da ys during each g ro uth stag e. There w as sig ni ficantva ria tion amo ng cul tivars in the deg ree o f orinetatio n of the cent ral and the side leaf letso f t ri folio lates at di fferent times of the day during bo th g row th stages. The o rientation o f the central leaflet s o f trifoliate dif fered f rom that of the side leaf lets. Hig her a ng les ofinclinatio n w ere obtained and maintained of th e cent ral leaflet than that of the sideleaf lets. How ev er , the v ertical inclinatio n o f leaflet s w ere higher than ho ri zontal inclination.On the other ha nd, larg er ang les o f inclination w ere obtained f rom the rightleaf lets tha n f rom lef t leaflet s. This may be due to the solar lig ht of di fferent locatio n.
