Effects of plant growth regulators on the carbohydrate accumulation in Simarouba glauca seedlings

A study was conducted to assess the accumulation of carbohydrate in germinating seeds as well as leaves, stem and roots of Simarouba glauca in response to various Plant Growth Regulators (PGRs). Field experiment was carried out to investigate effect of foliar application of PGRs like 6-benzylaminopurine (6-BA), gibberellic acid (GA), chlormequat (CCC), salicylic acid (SA), cysteine and methionine with 5 and 20 ppm concentration on carbohydrate content of Simarouba glauca DC whereas Seeds were subjected to 100 ppm solutions of various PGRs, which include GA, 6-BA, CCC, SA, Cysteine, and Methionine. It could be concluded that application of PGRs affect the carbohydrate metabolism or synthesis. Thus, the application of growth regulators in present study will be beneficial for induction of synthesis of primary metabolic products followed by synthesis of secondary metabolites of S. glauca

Influence of plant growth regulators on fatty acid composition of Simarouba glauca DC.

Simarouba glauca is a medicinally important oil yielding plant. It is a rainfed wasteland evergreen edible oil tree. Presowing soaked seeds of Simarouba glauca in various Plant Growth Regulators (PGRs) are analyzed to estimate their fatty acid composition. The fatty acids extraction was done using petroleum ether and fatty acid methyl esters (FAMEs) were analyzed by Gas Chromatography with Flame Ionization Detector (GC-FID). Due to the application of growth regulators stearic acid, lingoceric acid and linolenic acid enhances noticeably, while, total saturated fatty acids are augmented due to cysteine, Salicylic Acid (SA) and methionine treatments and monosaturated fatty acids elevated due to the application of 6-Benzylaminopurine (6-BA) whereas polyunsaturated fatty acids enhanced in response to Gibberellic Acid (GA) and Chlormequat chloride (CCC). The PGR induced changes in fatty acid composition predominantly in polyunsaturated fatty acids may certainly recover the oil quality of S. glauca seeds
