Tobacco Leaf Protein: I. An Evaluation of the Use of Putative Chemical Growth Enhancers for Tobacco Leaf Protein Production

Effects of foliar applications of long-chain fatty compounds on production of leaf protein from tobacco genotypes were evaluated. Triacontanol, purported to be a growth stimulant, had minimal effects on most experimental parameters. A propriety product, AgroLizer™, appeared to exert greater influenc...

An Evaluation of the Use of Putative Chemical Growth Enhancers for Tobacco Leaf Protein ProductionDe Jong DW0United States Department of Agriculture, Agricultural Research Service, Crops Research Laboratory, Oxford, North Carolina, U.S.A.Effects of foliar applications of long-chain fatty compounds on production of leaf protein from tobacco genotypes were evaluated. Triacontanol, purported to be a growth stimulant, had minimal effects on most experimental parameters. A propriety product, AgroLizer™, appeared to exert greater influence but results were inconclusive. Chemical treatments interacted with environmental conditions and tobacco genotype. Acid precipitation of the green fraction resulted in a pellet that could be easily removed by low speed centrifugation but produced a white fraction with lower protein percentage than heat precipitation of the green fraction. Triacontanol delayed flowering and extended vegetative growth in some genotypes. Increased cured leaf yields of flue-cured and Maryland type tobaccos were consistent but not statistically significant. An important finding was discovery of a genotype, T.I. 401, that produced high amounts of extractable leaf protein regardless of growth stage. This variety became the object of a follow-up investigation.https://doi.org/10.2478/cttr-2013-0619
