Second Growth


(1) Poorly developed shoots of cereal grains (rye, wheat, barley) that form later than the principal shoots as a result of protracted or excessive tillering. Second growth yields a small, deficient grain. Sometimes the shoots do not form any inflorescences (unfertile stems or sprouts). Because it requires water and nutrients, second growth adversely affects formation of grain of the principal shoots. Second growth in grains is fostered by sparse sowing, excessive rains after severe drought, injury to the tillering node, and late nitrogen feedings. Preventive measures include planting varieties that undergo tillering at the same time and observing seeding standards and other agrotechnical measures that ensure uniform development of plants.

(2) The aggregate of trees and shrubs introduced into a forest to accelerate vertical growth and improve the shape of trunks of the principal species. Fast-growing timber trees (birch, Norway maple, elm) and shrubs (Siberian pea tree, filbert) are used as second growth.
