Trirty seed lots of 8 cultivars of soyabean and 30 seed lots of 17 cultivars of Phaseolus bean from the U.S.A., Brazil and the Netherlands of high and commercially acceptable laboratory germination were sown in two field emergence experiments in 1992 in Aberdeenshire. A wide variation in field emergence was observed which was indicative of differences in the vigour of the seeds. Thus in both species (soyabean and Phaseolus bean) cultivars or lots which imbibed at faster rates gave rise not only to lower field emergence but also the emerged seedlings were smaller in size. The low vigour of seedlings originating from fast imbibing seed resulted from slower rate of transfer of food from the cotvledons to the shoot, as indicated by a significantly lower weight of the shoot, whice was negatively and significantly correlated with the rate of water uptake. |
