【 摘 要 】

http://dx.doi.org/10.5007/2175-7925.2014v27n4p37 The objective of this study was to evaluate the influence of four herbal plants on the germination and vigor of lettuce seeds, using aqueous preparations and teas ofMelissa officinalisL. (melissa),Rosmarinus officinalisL. (rosemary),Lavandula angustifoliaMill. (lavender) andCymbopogon citratus(DC.) Stapf. (lemongrass). A randomized complete block design was used with 9 treatments and 4 repetitions. The treatments were: melissa tea, melissa aqueous preparation, rosemary tea, rosemary aqueous preparation, lavender tea, lavender aqueous preparation, lemongrass tea, lemongrass aqueous preparation and control. The variables evaluated were: germination speed index, percentage of abnormal plants, percentage of germinated plants, fresh matter, dry matter, shoot length and radicle length. Lemongrass showed negative allelopathic effects on germination and vigor ofL. sativaL. Melissa tea had a stimulatory effect.
