Fig. 2. Relationships between rate of development and temperature for L. fendleri and L. mendocina in two different phenophases: (A) emergence to floral bud appearance, and (B) floral bud appearanc to first flower open. The solid lines were fitted by linear regression and broken lines were drawn by hand. Each point is the mean of ten plants for L. fendleri and of 6–10 plants for L. mendocina. Error bars indicate s.e. and are shown only when larger than the symbols.
