Pembangunan indek biokimia bagi spesies tumbuh-tumbuhan hutan hujan tropika menggunakan spektroradiometer lapangan

Biochemical elements such plant pigment chlorophyll, carbon, nitrogen and water can affect the physiology and penology development of the plants. However, the traditional method of foliar analysis is no longer able to meet the growing need for biochemical element information. Consequently, this rese...

Consequently, this research aims to use vegetation index (VI) model as an alternative method for the production of biochemical element information.
