Electromagnetic effects on seed germination of moringa cultivars
(International Society for Horticultural Science, 2021-04)
Most recently, electromagnetic application in agriculture has increased since plant features were altered significantly in response to pre-sowing seed treatment. Moringa has an extraordinary range of industrial and medicinal uses. This miracle tree is an extremely precious plant with great nutritive importance. The aim of this study was to determine the effect of pre-sowing magnetic field (MF) treatments on seed germination and seedling growth in Moringa oleifera, M. peregrina and M. oleifera cultivar 'Periyakulam-1' (PKM-1). These laboratory experiments were carried out at the premises of the Sara bint Rached bin Ghonaim Research Chair for Cultivating non-Traditional Medicinal and Aromatic plants (SRC), PSAU, Alkharj (24°15'N, 47°30'E), KSA. Three treatments were established using a 75 mT (millitesla) MF with 30 min exposure duration to the seeds of: MFO (T1): seeds of Moringa oleifera; MFP (T2): seeds of M. peregrina; MFPKM (T3): seeds of PKM 1. The obtained results exhibited significant effects on most of the germination parameters; mean germination time (MGT), seedling vigour index (SVI), energy of germination (EG), and final germination percentage (FGP). M. peregrina exhibited the best attributes for most parameters compared to Moringa oleifera and M. oleifera cultivar 'Periyakulam-1' (PKM-1). These findings indicate the possible use of MF treatments for the seed germination and seedling growth of moringa that should be considered in further research studies....
A study on the nutritional quality of Moringa oleifera and Moringa peregrina
(International Society for Horticultural Science, 2021-04-15)
A study was conducted to determine and compare the growth characteristics and nutritional quality of M. oleifera and M. peregrina. Three moringa cultivars consisting of two M. oleifera cultivars (‘PKM-1’ and ‘Local’) and one M. peregrina cultivar were evaluated in pot experiments using a randomized complete block design with four replications. Pruning and sampling of leaves for biomass yield and nutritional quality analysis were performed when plants attained a height of 1 m. Young and fully expanded green leaves were sampled for nutritional analysis and biochemical components. Results showed that plant height and number of leaves differed significantly between the three cultivars. ‘PKM-1’ and the ‘Local’ cultivar were taller than M. peregrina, whereas, ‘PKM-1’ and M. peregrina produced a higher number of leaves than the ‘Local’ cultivar. There were no significant differences in the number of side branches among cultivars. Although there were no significant differences in leaf fresh weight among cultivars, M. peregrina and ‘PKM-1’ had a tendency of higher leaf fresh weight than the ‘Local’ cultivar. Both cultivars had significantly higher dry leaf biomass than the ‘Local’ cultivar. Significant differences in calcium, iron and anti-oxidant activity were found between the three cultivars. ‘PKM-1’ contained higher calcium than M. peregrina and the ‘Local’ cultivar. ‘PKM-1’ also contained higher iron than M. peregrina, but not significant compared to the ‘Local’ cultivar. Both ‘PKM-1’ and M. peregrina had significantly higher anti-oxidant activity than the ‘Local’ cultivar. Significant differences were also observed in nitrogen free extract, crude protein and crude fat. Nitrogen free extract content was higher in M. peregrina than in ‘PKM-1’ and ‘Local’ cultivar. The ‘Local’ cultivar contained higher crude fat than ‘PKM-1’ and M. peregrina. This study indicated that moringa cultivars differ in growth characteristics, selected nutritional qualities and biochemical components. Further studies should investigate and determine other nutritional qualities that are not covered including vitamins, amino acids and important anti-oxidants....
