The Physical Environment.—We have seen (354) that the environment in which a plant grows is made up of two sets of factors—the physical environment of climate and soil, and the organic environment of competing animals and plants. 367. Modifications to Climate in General.—Every par- ticular climate induces particular modifications in its plants. There are two general ways, however, in which plants are modified by climate: modification in

Modifications to Climate in General.—Every par- ticular climate induces particular modifications in its plants. There are two general ways, however, in which plants are modified by climate: modification in the length of the period of growth; modification in stature. Any modification of the plant, visible or invisible, that enables it to grow in a climate at first injurious to it, is acclimatization. 368. In short-season climates, plants hasten their growth. They mature quickly. Indian corn may require five or six months in which to mature in warm countries, but only three months in very cold countries. Garden vegetables probably mature quicker from the time of planting in the North than in the South 378.

Some seedsmen think this to be true and they like to raise seeds of early varieties in the North, for such seeds usually give "early" plants. Many plants that are perennials in warm countries become annuals or plur- annuals in cold countries (14). 369. Plants are usually dwarf or smaller in stature in (212).
