Coding the Phenology of endangered Lilium mackliniae Sealy using extended BBCH scale

Abstract

Lilium mackliniae Sealy is an endemic lily of North-East India. The changing climate conditions, human activities, and natural resource exploitation have pushed the lily population to the brink of extinction. It has been well documented that the need to conserve L. mackliniae is in its critical stage. Plant phenology is closely correlated with environmental and human-caused factors. Therefore, a well-defined study of phenological traits can aid conservation aims. This paper utilized the BBCH scale to study its phenological characteristic, described by Phenological Growth Stages (PGS) in response to environmental conditions. Our findings can help the researchers as a means of conservation strategies
