“…Thus for the first time the complex nature of the alkane fraction was revealed [3]and the presence of large quantities of iso-alkanes demonstrated besides the more usual normal alkanes. These findings have been confirmed [4] and elegantly extended recently [5]. The alcohol fraction has been shown to contain stigmasterol, Pand ')I-sitosterol [6], solanesol, and n-docosanol [7].…”

“…As expected, the major alkanes of the leaf waxes were C29 and C31. The hydrocarbon compositions of leaf wax from rutabaga (Waldron et al, 1961), red beet (Strfinsk) et al, 1967) and carrot (Nishimoto, 1973) have been previously reported. The results of the first two studies agree with our findings, whereas in the case of carrot leaves our results showed that n-C29 is the major alkane but n-C2v was previously reported to be the major alkane.…”

The waxes associated with the suberin in the periderm of the underground storage organs of parsnip (Pastinaca sativa L.), carrot (Daucus carota L.), rutabaga (Brassica napobrassica Mill.), turnip (Brassica rapa L.), red beet (Beta vulgaris L.), sweet potato (Ipomoea batatas L.) and potato (Solanum tuberosum L.) were isolated, fractionated into hydrocarbon, wax ester, free fatty alcohol and free fatty acid fractions, and analyzed by combined gas chromatography and mass spectrometry. The amount of wax extracted from the periderm of the storage organs ranged from 2 to 32 μg/cm(2). The hydrocarbons from the suberin layer have a broader chain-length distribution, a predominance of shorter carbon chains, and a higher proportion of even-numbered carbon chains than the leaf alkanes from the same plants. The major components of the free and esterified fatty alcohols and fatty acids have an even number of carbon atoms, and are similar in chain-length distribution to their counterparts found covalently attached to the suberin polymers; however, these suberin components are shorter in chain length than their cuticular analogues from the leaves. Also extracted from the storage organs were polar components which included fatty alcohols and fatty acids in a conjugated form, and ω-hydroxy acids and dicarboxylic acids. Evidence is presented that removal of the wax from the periderm of whole storage organs results in a decrease in diffusion resistance to moisture.

“…Chibnall and colleagues later verified this early finding by mass spectroscopy. 2 Our initial studies in 1975 showed that coarsely chopped alfalfa increased the growth of plants when applied as a sidedressing in a band below and to the side of the crop seeds or seedlings. 3 An application of 117 kg of dry alfalfa per hectare increased early tomato (Lycopersicon esculentum) yields by 10 metric tons per hectare.…”
