FROST HARDINESS OF COMMONLY GROWN POTATOES (SOLANUM TUBERROSUM) L.

G.F. Collet, V. Dvorak, c.L. Lê
Frost hardiness experiments and duration of conservation at +3°C ± 1 were performed with in vitro minicuttings of potato varieties (Swiss assortment). Ability to support lethal temperature (-6°C) depends on the time of cold hardening. Short warm period (72 h at 18°C) just before testing at negative Temperature does not modify this ability. Contents of amino acids were compared between cold hardening and normal stolons.
