Figure 1. Temperature and phenological data for (A) 2003; (B) 2004. Top: Daily (thin line) and 15-d (thick line) mean temperatures from Day 91 to 294 on a day of year (DOY) scale. Middle: Progression of biweekly vegetative node number (Vn) in each planting date. Vn values of –2 and –1 were arbitrarily used to denote the sowing and emergence (VE) stages. Bottom: Progression of biweekly reproductive stage (Rn) number in each planting date. The staging system of Fehr and Caviness (1977) was used. Each V- and R-stage data symbol represents a mean of 140 plants.
