摘要：

Frost damage in young fruits of white sapote (Casimiroa edulis Llave & Lex.) cv.'Florida' was investigated under Japanese field conditions and in artificial growth chambers to identify the relationship between frost damage in young fruits and the low yield which occurs under the open-field culture of this sub-tropical fruit crop. In the crops grown in the field under Japanese climatic conditions, no fruits were produced in years when the minimum temperature dropped below -2.5.DEG.C.. Severe frost damage was observed in young fruits at -3.DEG.C. in an artificial growth chamber, and no frost damage was observed at -2.DEG.C. after four consecutive days of exposure to five hour/day treatments. We recommend that commercial cultivation of white sapote take place at locations where minimum winter temperatures do not exceed -2.0.DEG.C..
