Temperature and flooding depth thresholds for early recruitment stages in a bulbous plant Bolboschoenus planiculmis

Early recruitment process dominated by vegetation reproduction for wetland plant is a key life-history stage affecting species distribution. Extreme climatic events, such as extreme temperature and heavy rainfall have been predicted to become more intense frequent under future climate scenarios. To explore the effect of flooding depth on tubers sprouting early growth Bolboschoenus planiculmis, we conducted two artificial experiments in incubator greenhouse, including ten regimes (8, 10, 12, 14, 16, 19, 22, 25, 28 31 °C), treatments (− 5, 0, 3, 6, 9, 20, 30 40 cm). The results showed that had significant tuber ramet growth. estimated base 6.2 °C, final percentage increased parabolically with increasing reached maximum 61.09% at 25.4 °C. first then decreased depth, 96.04% 3.92 cm. height 61.29 cm 8.20 Our study will provide basis understanding predicting influence change distribution B. planiculmis.
