Abstract：

Moso Bamboo（Phyllostachys edulis）is one of the major forests in tropical and subtropical regions. Chlorophyll content (Chl) is an indicator of soil fertility, and establishing a relationship between in situ optical chlorophyll content (such as Soil and Plant Analyzer Development - SPAD, unit less) and in vitro absolute chlorophyll content (Chl，uɡ/cm²) will facilitate large scale soil fertility management. 30 samples were collected from Moso Bamboo leaves in Deqing county, Zhejiang province, China (30°32'53.89"N, 119°55'1.27"E) on 23 October 2018. The in situ SPAD readings range from 27.4 to 47.6, with an average of 40.47. The in vitro absolute chlorophyll content（Chl，uɡ/cm²）was determined using 95% ethanol and 80% acetone (1:1), as well as spectrophotometer, with a span of 26.51-70.72 (uɡ/cm²) and an average of 51.84 (uɡ/cm²). Analysis of correlation suggests that the best relationship between SPAD and Chl (uɡ/cm²) can be expressed as exponential（Chl = 5.8775e^0.0525*SPAD）, with a coefficient of determination (R²) of 0.9287. This dataset includes: (1) geo-location of sample sites; (2) in situ SPAD readings and in vitro chlorophyll concentration measuring of Moso Bamboo（P. edulis）and the relation data between them. The dataset is archived in .kmz, .shp and .xlsx data formats, consist of 8 data files with data size of 20.9 KB (Compressed to 2 files with data size of 17.8 KB).
