Abstract

This study aimed to evaluate the phytotoxicity and allelopathic potential of hydrolats of Croton argyrophylloides Muell. Arg., C. blanchetianus Baill., C. jacobinensis Baill., C. nepetaefolius Kunth., C. sincorensis Mart. ex Muell. Arg. and C. zehntneri Pax. et. Hoff m. in the germination of diaspores of lettuce and tomato. There were daily observations and measurement of the standard test of germination (TSG), fi rst count (1a C) and germination speed index (GSI). The intensity of the phytotoxic activity of each species varied according to concentration, species and photoperiod. C. argyrophylloides , C. blanchetianus , and C. nepetaefolius were inhibited in all photoperiods. Some stimulating eff ects were observed for C. sincorensis and C. argyrophylloides . Nevertheless, the results of this study provide consistent indications of the allelopathic potential of tested species.

6种巴豆属植物对生菜和番茄萌发的化感作用潜力

本研究旨在评价巴豆水合物的植物毒性和化感作用。参数。C. blanchetianus Baill。， C. jacobinensis Baill。C. nepetaefolius Kunth;C. sincorensis Mart。Muell交货。参数。和C. zehntneri Pax。等。Hoff m.莴苣和番茄胚芽萌发的影响。每天进行发芽标准试验(TSG)、初计数(1a C)和发芽速度指数(GSI)的观察和测定。各物种的植物毒性活性强度随浓度、种类和光周期的不同而不同。在所有光周期内，银叶卷叶卷木、白桦卷叶卷木和nepetaefolius均受到抑制。对银杏和银杏有一定的刺激作用。尽管如此，本研究的结果提供了一致的指示，表明被测物种的化感作用潜力。
