将白色三叶草、红色三叶草和荷花种种植在玻璃边的盒子中，观察反复落叶和遮光对根和根瘤生长的影响。对于白色三叶草，遮荫导致根系和根瘤明显损失，随后几乎没有新的生长。然而，在经常性的落叶情况下，新的生长物足以抵消根部和根瘤的损失，导致根部和根瘤组织的迅速更替。对于红三叶草，根和根瘤的损失较慢。有没有再生长的阴影植物和很少在经常落叶植物，导致一个较小的营业额的根和根瘤组织比白色三叶草。与莲花有一个快速的损失结节和一些根在两个治疗，只有轻微的再生在落叶植物。
Summary White clover, red clover, and a lotus species were grown in glass-sided boxes and the effects of recurrent defoliation and of shading on the growth of roots and nodules were observed. With white clover, shading led to marked loss of both roots and nodules with little subsequent new growth. Under recurrent defoliation, however, the loss of roots and nodules was more than counterbalanced by new growth, leading to a rapid turnover of root and nodule tissue. With red clover, the loss of roots and nodules was slower. There was no regrowth in the shaded plants and little in the recurrently defoliated plants, leading to a smaller turnover of root and nodule tissue than with white clover. With lotus there was a rapid loss of nodules and some roots in both treatments, with only slight regrowth in the defoliated plants.
