Potencial alelopático de seis espécies do gênero Croton L. na germinação de alface e tomate
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.
期刊介绍：
The Iheringia, Série Botânica is a publication edited by the Museu de Ciências Naturais, Fundação Zoobotânica do Rio Grande do Sul, since 1958. The name Iheringia is actually a tribute to Hermann von Ihering (a German researcher who became a Brazilian citizen) and his important studies in the Natural Sciences.The journal has the mission of publishing articles, reviews and original scientific notes that cover diverse areas in Botany, and may be written in Portuguese, Spanish and English.
The journal is widely available in both international and national scientific community. The issues are published and distributed twice a year to 118 national institutions and 152 international institutions. The distribution is either free of charge or by exchange.
