摘要:
Seedlings representing offspring from 46 Swedish natural standsof Pinus sylvestris(L.) from latitude 63° to 68° and altitude 75 to 675 m were artifically frost hardened and tested for autumn frost hardiness using artifical freeze testing in a programmable freezing chamber. A clinal variation in frost hardiness was observed over latitude. Altitude had no effect on the frost hardiness. The results are discussed in relation to the reproduction‐ and migration biology ofP. sylvestris.
