Abstract
ABSTRACT Guttation is the mechanism by which liquid exudes from hydathodes located on the tip, along the margins, and on the adaxial and abaxial surfaces of leaves. In contrast to stomata, hydathodes, also known as water stomata or water pores, are often open, representing the path of least resistance to liquid outflow from them. Guttation fluids are made up of several organic compounds. This paper focuses on the defensive properties of the chemical compositions of the guttation extracts of Oryza sativa, Momordica charantia, Luffa acutnugula, and Ricinus communis extracted using five different solvents, which were analyzed using Gas Chromatography–Mass Spectrometry (GC-MS). The mass spectra of the compounds present in the guttation fluids were matched by the National Institute of Standards and Technology (NIST) library. GC-MS analysis of guttation fluid extracts of crop plants revealed the existence of compounds with antifungal and antimicrobial properties which may act as barriers to pathogens. The numerous compounds found in plant extracts, such as fatty acids, organic acids, and terpenoids, have a wide range of protective activities and mechanisms that can serve as the first line of defense against pests and diseases.
期刊介绍:
Journal of Crop Science and Biotechnology (JCSB) is a peer-reviewed international journal published four times a year. JCSB publishes novel and advanced original research articles on topics related to the production science of field crops and resource plants, including cropping systems, sustainable agriculture, environmental change, post-harvest management, biodiversity, crop improvement, and recent advances in physiology and molecular biology. Also covered are related subjects in a wide range of sciences such as the ecological and physiological aspects of crop production and genetic, breeding, and biotechnological approaches for crop improvement.
