Environmental Influences on Growth and Reproduction of Invasive Commelina benghalensis

Table 2

Effects of three temperature regimes on C. benghalensis aerial and subterranean spathe production. Data for the photoperiod treatments were similar, statistically, so they were combined.

Temperature regime	Aerial spathes			Subterranean spathes
	Days after treatment			Days after treatment
	28	42	56	28	42	56
°C	Number of spathes plant^−1
35/28	18	68	87	4	30	31
30/22	22	94	120	1	15	22
30/30	42	84	98	5	25	37
	4	15	20	1	5	5

Numbers indicate day/night temperatures.
Values are means of 24 replicates. Photoperiod effects were nonsignificant at the 35/28 and 30/22°C temperatures, so data were pooled for each temperature regime.
