In: Botanical GazetteSummary: La remocion de hojas por encima de la primera hoja trifoliada de plantas de frijol (Phaseolus vulgaris L. var. Canadian Wonder) produjo expansion foliar mas rapida, area foliar final mas grande, peso seco mas alto, area foliar especifica mas baja y tasas de fotosintesis mas altas en la primera hoja trifoliada en comparacion con los testigos no defoliados. La remocion de las hojas primordiales tan pronto como se desarrollaron, produjo expansion foliar inicial mas rapida, area foliar final mas pequena, peso seco mas bajo, area foliar especifica mas alta e, inicialmente, tasas mas altas de fotosintesis en la primera hoja trifoliada en comparacion con testigos no defoliados. (RA-CIAT)Summary: Removal of leaves above the 1st trifoliolate leaf of bean plants (Phaseolus vulgaris L. Canadian Wonder) induced more rapid leaf expansion, a larger final leaf area, higher dry wt, lower especific leaf area and higher photosynthetic rates in the 1st trifoliolate leaf compared with undefoliated controls. Removal of the primary leaves just after they unfolded induced more rapid initial leaf expansion, smaller final leaf area, lower dry wt, higher specific leaf area and initially higher, but subsequently lower rates of photosynthesis in the 1st trifoliolate compared with undefoliated controls.
