Abstract:
During the autumn senescence period in years 2018, 2019, 2020, 2021, 2023 and 2024 we used a chlorophyll meter (Konica-Minolta, Japan, SPAD-502) to collect SPAD values from 5 replicate leaves of 5 native (Ribes americanum Wild currant; Prunus virginiana Chokecherry; Euonymus atropurpureus Eastern wahoo or Burning bush (added in 2020); Viburnum lentago Nannyberry; Cornus alternifolia Pagoda dogwood; ) and 4 non-native (Lonicera morrowii Honeysuckle; Rhamnus cathartica Common Buckthorn; Ligustrum vulgare European privet; Viburnum opulus European highbush cranberry) temperate deciduous shrub species growing in Downer Woods - a small urban woodlot on the campus of the University of Wisconsin-Milwaukee, USA. SPAD values were recorded at least twice weekly on all species when leaves were present. On each occasion SPAD readings were recorded at the same location on each of five leaves from 2 to 7 replicate plants of each species. SPAD values were converted to leaf chlorophyll using calibration equations from a previous study (Donnelly et al. 2020, doi:10.1007/s13595-020-00940-6).
