About April 1 the plants in the cool house began to outstrip the plants in the warm -house in their growth rate, and in particular in their tendency to maintain an upright growth habit. The total amount of tissue formed at.

By April 19 all plants in the cool house had outstripped those in the warm house. The most striking difference between the two.
