| An anthocyanin-free tomato plant, H957, and its parental wild type, H883, were hydroponically grown to test for tolerance to a low phosphorus (P) in H957. The tolerance was evaluated by comparing growth and metabolism of H957 vs. H883 at different P concentrations ranging 25~400$mu$M. Fresh weights were measured weekly. Dry weight, mineral contents, photosynthetic rate, and P utilization rations of the plants were measured after five weeks of growth in the hydroponic culture. Although the growth of both varieties was severely impaired at 25 $mu$M P, H957 showed a greater fresh weight and dry weight at 50~400 $mu$M P. H957 showed a higher net photoxynthetic rate on older leaves while both varieties showed similar photosynthetic rate on young leaves. H957 tissue contains an overall lower P concentration in its tissue than H883. These observations together indicate that the anthocyaninless mutant H957 tolerate to lower P concentration. It does so by utilizing internal P with better efficiency rather than by absorbing external P better. |
