WebWe observed the fine root lifespan of 12 temperate tree species using minirhizotrons in a common garden and compared their median lifespans with fine-root and whole-plant traits. We then determined which set of combined traits would be most useful in predicting patterns of root lifespan. Median root lifespan ranged widely among species (95-336d ... WebApr 19, 2002 · The overall root life span differed among the four species (F 3,70 = 26·1; P < 0·001), varying from 14 weeks for L. perenne roots to 58 weeks for N. stricta. The overall life span of L. perenne roots was significantly shorter than that of A. elatius, M. caerulea and N. stricta roots (P < 0·001) .
