A hydromethanolic extract showed general stimulatory effects. The EtOAc extract stimulated root elongation and root weight of tomato; shoot elongation was inhibited, while shoot weight was not altered. The pure amenthoflavone isolated from the plant, stimulated shoot elongation at concentrations ranging between 10(-4) M and 10(-6) M.121-124engByrsonima crassaamenthoflavonetomato seedsgerminationshoot weight and elongationroot weight and elongationArtigo10.1080/17429140701561483WOS:000207809000007Acesso restrito79278772243268370000-0003-3032-2556
