Abstract:
INTRODUCTION

Technological advances in electronics have provided us with new equipment to enhance our ability to quantify treatment differences in plant material One such instrument provides a non-destructive evaluation of leaf chlorophyll levels. Early testing and present use of this instrument focuses on nitrogen fertility of grasses (usually grain crops). The work has resulted in a rapid determination of nitrogen crop fertility levels that identifies fertilization needs for the crop.

This study was initiated to determine if a chlorophyll meter could be a useful tool for production of woody nursery stock. Preliminary information indicated a possible relationship between perceived growth and chlorophyll readings within species. Verification of a correlation between chlorophyll levels and growth of related plant material could allow plant breeders to use information as early indicators of plant performance.

This report is the result of 2-years' data that measured chlorophyll levels
