Abstract
Garlic (Allium sativum L.) is ayurvedic herb that has been extensively used as medication and as the taste enhancer of the food. The impacts of foliar spraying of Garlic with different concentration (0.5, 1, 25 and 50%) from Spirulina platensis, Ulva fasciata or Pterocladia capillacea liquid extract on the growth, pigment, protein content, macro, micronutrient and phytochemical components were investigated. The findings demonstrated that the foliar spraying of garlic with 25% Spirulina resulted in an increase in leaf length, chlorophyll a and protein content by 49, 20 and 18%, respectively. Also, the total N and S increased by 1.2 and 5 folds, respectively. The examination of hexane and methanol extracts from control and treated plants with 25% Spirulina extract using GC-MS revealed a significant rise in the percentage of concentration of Diallyl disulphide, Trisulfide, methyl 2-propenyl, 2-Methoxy-4-vinylphenol and Phytol by 1.3, 1.9,1.5,2.7 in case of 25% Spirulina extract relative to the control plants. Spirulina platensis extract can be employed to improve the growth, minerals, organosulfur compounds of garlic.
