Effect of plant-derived smoke on germination, seedling vigour and growth of rapeseed (Brassica napus) under laboratory and greenhouse conditions
This study highlights the influence of various dilutions of aqueous smoke extract (1/500, 1/100, 1/10 and 1/1 v/v) on germination, seedling vigour and growth traits of rapeseed (Brassica napus cv. Okapi) under laboratory and greenhouse conditions. Smoke extract treatments (1/100 and 1/500 v/v) significantly (P < 0.05) enhanced the germination percentage (25-28%), vigour index (up to 4-fold) and germination speed (up to 2-fold) compared with control. In greenhouse experiments, pre-soaking seeds in smoke dilutions of 1/500 and 1/100 significantly (P < 0.05) enhanced the growth of rapeseed plants at 30 and 50 days after seed sowing (DASS) compared with control. At 50 DASS, these smoke-extract dilutions increased the root length (22.5-65%), plant height (41-47.5%), root dry weight (2.4- to 3.4-fold), shoot dry weight (4.6- to 5.1-fold) and leaf area (3- to 3.7-fold) of rapeseed plants compared with untreated seeds.
