The experimental work presented in this study was carried out with the hypothesis that plant derived smoke enhanced the morphological, physiological and biochemical attributes of a cereal crop, wheat (Triticum aestivum L.). Furthermore, this study supported the hypothesis that plant derived smoke acts as vegetative growth promoter, inexpensive, rapid and most appropriate eco-friendly bio-fertil...

The ability of plant-derived smoke to act as a germination cue in many species has led to widespread interest in this aspect of seed biology. Recently, 3-methyl-2H-furo[2,3-c]pyran-2-one was identified as the main germination cue from smoke. Here, we report on the formation of this compound from reactions of sugars with amino acids. Heating proteins or amino acids with sugars at 180 degrees C f...

BACKGROUND In order to understand and generalize the toxic mechanism of cigarette smoke in living cells, comparison of the data between animal systems and other biological system such as microbial and plant systems is highly beneficial. OBJECTIVE By employing the tobacco cells as model materials for cigarette smoke toxicity assay, the impacts of the combustion by-products such as nitrogen oxi...

C4 and C3 grasses were subjected to burning in the laboratory to determine whether there was any significant fractionation of carbon isotopes between plant material and corresponding ash and smoke produced from burning. The results show that smoke produced from C4 grasses is generally depleted in C relative to the original plant, but the magnitude of the C depletion varies with species from <0....

Plant-derived smoke has been known to play an important role in distribution and growth of vegetation. Using a proficiently designed furnace, we extracted smoke from the leaves of four plant viz. Helianthus annuus,Aloe vera,Ginkgo biloba, and Cymbopogon jwarancusa. Smoke dilutions obtained from these plants were obtained in different concentrations to identify potential lettuce growth promoting...

Smoke plays an intriguing role in promoting the germination of seeds of many species following a fire. Recently, a bicyclic compound containing a condensed butenolide moiety, 3-methyl-2H-furo[2,3-c]pyran-2-one (1), was reported as a potent germination promoter from plant-derived smoke. In this study, a related butenolide, 3,4,5-trimethylfuran-2(5H)-one (2), which inhibits germination and signif...
