DENDROLOGY

Detailed explanation-1: -Potato is mostly cultivated by planting tubers. Purity of the cultivars and healthy seed tubers are the primary requirements for a successful crop. However, seed tuber is the costliest input in potato cultivation. The tuber seed should be disease free, well-sprouted and 30-40 g each in weight.

Detailed explanation-2: -The potato is a typical tuber, as is the Jerusalem artichoke. The term is also used imprecisely but widely for fleshy roots, corms, or rhizomes of other plants that resemble tubers-e.g., the “tuber” (actually a tuberous root) of a dahlia.

Detailed explanation-3: -The potato tuber is an enlarged portion of an underground stem or stolon (Figure 1.1-1). Tuber eyes are the buds from which next season’s growth will emerge. Eyes are concentrated near the apical end of the tuber, with fewer near the stolon or basal end. Eye number and distribution are characteristic of the variety.
