Table 1

Days from emergence to harvest, total number of leaves, leaf appearance rate, thermal time, and accumulated thermal time (±standard error) for three sugarcane cultivars in Northeastern Mexico under high temperature rainfed conditions.

Cultivar	Emergence to harvest; (days)	Total number of leaves	Leaf appearance rate; (leaves·day^−1)	Thermal time; (°C·day^−1·leaf^−1)	Accumulated thermal time (°Cd)
Mex 68-P-23
CP 72-2086
Mex 79-431
Mean	366.7	41.3	0.113	136.9	5558.8
CV (%)	2.13	2.15	2.25	2.38	2.31

Means ± SE within a parameter not followed by the same letter are significantly different at according to Tukey’s multiple range test.
