“…These plants also had the lowest height and fresh weight. This response is not novel; early studies have shown an inverse correlation between total phenols or flavonoids and plant growth (Chandramohan et al, 1973;Conley, 1988;Haukioja and Siren, 1985). Despite the high levels of total phenols and flavonoids, the antioxidant capacity of spearmint or peppermint essential oil samples did not change between the 0, 50, and 100% CBMW treatments.…”

The Effect of Coal-Bed Methane Water on Spearmint and Peppermint

Coal bed methane is extracted from underground coal seams that are flooded with water. To reduce the pressure and to release the methane, the water needs to be pumped out. The resulting waste water is known as coal bed methane water (CBMW). Major concerns with the use of CBMW are its high concentrations of S, Na, dissolved Ca, Mg, SO, and bicarbonate (HCO). Irrigation water is a scarce resource in most of the western states. The objective of this study was to evaluate the effect of various amounts of CBMW on the growth, essential oil content, composition, and antioxidant activity of spearmint ( L.) and peppermint ( L.) crops that were irrigated with the water. These two crops are grown in some western states and are potential specialty crops to Wyoming farmers. The irrigation treatments were 0% CBMW (tap water only), 25% CBMW (25% CBMW plus 75% tap water), 50% CBMW (50% CBMW and 50% tap water), 75% CBMW (75% CBMW plus 25% tap water), and 100% CBMW. Analyses of the data revealed that the CBMW treatments did not affect the antioxidant capacity of spearmint or peppermint oil (242 and 377 μmol L Trolox g, respectively) or their major oil constituents (carvone or menthol). Coal bed methane water at 100% increased total phenols and total flavonoids in spearmint but not in peppermint. Coal bed methane water also affected oil content in peppermint but not in spearmint. Spearmint and peppermint could be watered with CBMW at 50% without suppression of fresh herbage yields. However, CBMW at 75 and 100% reduced fresh herbage yields of both crops and oil yields of peppermint relative to the control.

Allelopathy is the inhibitory or stimulatory effect of a plant (donor) on other plants (receivers) through the chemicals released from the donor plant to the environment, mostly into the soil. These chemicals may reach the receiver plants in various ways, including leaching from plant foliage, exudation from the roots, and decomposition of dead residue of the donor plants. However, allelopathy in soil is a complicated phenomenon that is affected by soil condition, growth condition of the donor and receiver plants and climatic condition. Allelochemicals in soil are adsorbed on soil solids, and metabolized by chemical and biological reactions during the movement in soil. This behavior is affected by various soil factors, such as soil texture, organic and inorganic matter, moisture and organisms, which affect the phytotoxic activity in soil. If an allelochemical can directly affect the growth of receiver plants in soil, then the allelochemical might be present in the soil water so that it is directly available for absorption by the plant. Thus, it is suggested the concentration of an allelochemical in soil water is a dominant factor directly determining the phytotoxic activity in soil, and the concentration is controlled by soil factors that affect the behavior of adsorption, desorption and degradation in soil.

“…Soil sickness and accompanying reduced. yields have often been attributed to inhibitory chemicals released from decomposing plant residues (2,15). Allelopathic chemicals may inhibit crop growth directly, or may increase susceptibility of the crop to plant pathogens (1,6,16).…”

Salicylic acid,p-hydroxybenzoic acid, caffeine, hydroquinone, and umbelliferone were evaluated in the greenhouse for their effects on shoot dry-weight accumulation of several crop and weed species. With the exception of caffeine, all the chemicals reduced shoot growth in oats (Avena sativaL. ‘Goodfield’). Chemicals applied preplant incorporated, preemergence, or postemergence were effective, depending upon the rate of chemical. When applied preplant incorporated at rates as high as 56.0 kg/ha, most of the chemicals reduced growth of corn (Zea maysL. ‘B73 × Mo17′), soybean [Glycine max(L.) Merr. ‘Corsoy’], velvetleaf (Abutilon theophrastiMedic.), redroot pigweed (Amaranthus retroflexusL.), and wild proso millet (Panicum miliaceumL.). Exceptions were caffeine on corn and soybean and hydroquinone on soybean. At 11.2 kg/ha the chemicals inhibited the weed species more than the crop species. Postemergence applications of caffeine and hydroquinone inhibited growth of the weed species more than the crop species. Hydroquinone at 1.1 kg/ha inhibited redroot pigweed, but rates as high as 11.2 kg/ha did not inhibit soybean. These experiments show that growth of agronomically important crops and weeds can be inhibited differentially by allelopathic chemicals.
