TABLES
Table 1. Chionochloa pallens plants used for leaf sample collection in this study. All plants were initially growing at 1070 m on Mt Hutt. The site elevations are in metres above sea level; compared to the 1070 m site, mean temperatures at 15 m are about 6 °C warmer and at 1520 m about 2 °C cooler (Kelly et al. 2008). For each row, we took leaf samples from three tagged tillers, from each of 10 tagged plants (20 plants for 16Cool). Flowering intensity is the percentage of surviving tillers the following year which flowered (with N surviving tillers in brackets).
