摘要: 以4种地被竹(铺地竹(Arundinaria argenteostriata)、菲白竹(Arundinaria fortune)、鹅毛竹(Shibataea chinensis)、黄条金刚竹(Sasaella masamuneana f.aureostriata))为材料,研究了它们的蒸腾特性。结果表明,各竹种4月份、8月份蒸腾日变化均为“双峰型”曲线,中间出现短暂的“午休”现象,但各竹种蒸腾速率高峰值出现的时间不同,在11月份则为“单峰型”曲线。其中8月份各竹种的蒸腾速率要大于其余两个月份。各竹种竹秆、叶片蒸发速率与温度、光照呈正相关,且相关性水平达到极显著,与湿度呈负相关,相关性达显著水平。

Abstract: The dynamic variation of transpiration and evaporation rates of 4 dwarf bamboos (Arundinaria argenteostriata, Arundinaria fortune, Shibataea chinensis, Sasaella masamuneana f.aureostriata) were measured. The results showed that the diurnal variation of transpiration rate was a double peak curve in April and August, stoma partly closed was the chief reason, however the peak time of transpiration rate of different bamboo species reach the was different. A single peak curve appeared in November and the transpiration rate of August was the highest among the tested 3 months. The correlation analysis indicated that the evaporation rate of culm and leaves significant positively correlated with temperature and illumination,and significant negatively correlated with humidity.
