Abstract:
a Pecan nuts of Western cultivar, harvested November 5, 1974, were divided into three lots. One lot of the nuts was stored dry at room temperature, the other lot stored dry at 1. 66°C and the third lot was stratified in moist peat-moss and stored dry at 1.66°C. Nuts were planted at weekly intervals from November 19, 1974 to January 21, 1975 and at 4-week intervals after January 21, to June 10, 1975. The germination data indicated that the period of germination of pecan nuts decreased as the length of time of stratification increased. After 18, 22, 26 and 30 weeks of storage, 80 per cent of the stratified nuts germinated within 21.4, 15.0, 15.4 and 13.8 average days respectively. Nuts stored dry at 1.66°C germinated fairly well in a short period of time when planted 22, 26 and 30 weeks after storage, but still these nuts took a longer time than did stratified nuts to reach 80 per cent germination. Germination was more rapid with stratified nuts, and results of the stratification treatment were significantly different from results of the nuts stored dry at 1.66°C. Nuts stored at room temperature for 22 weeks began to develop rancidity and germinated only 66 per cent. Nuts stored at room temperature for additional period germinated, even less.
