摘　　要：Wind is an environmental stimulus that stresses plants of all growth forms at all life-stages by influencing the development,architecture,and morphology of roots and shoots.However,comparative studies are scarce and no study directly investigated whether shoot and root morphological traits of trees,grasses and forbs differ in their response to short wind pulses of different wind intensity.In this study,we found that across species,wind stress by short wind pulses of increasing intensity consistently changed root morphology,but did not affect shoot morphological traits,except plant height in four species.Wind effects in roots were generally weak in tree species but consistent across growth forms.Furthermore,plant height of species was correlated with changes in specific root length and average diameter.Our results indicate that short-pulse wind treatments affect root morphology more than shoot morphology across growth forms.They further suggest that wind stress possibly promotes root anchorage in young plants and that these effects might depend on plant height.
