Abstract
Embryo growth of the pecan (Carya illinoensis (Wang.) K. Koch) is mechanically restricted by the shell. This effect can rapidly be overcome by germinating the seeds between 30 and 35°C.
Abstract
Chilling requirements for 3 pecan cultivars are reported for the first time. Stem cuttings with 4 buds of ‘Desirable’, ‘Mahan’, and ‘Stuart’ pecan (Carya illinoensis (Wang.) K. Koch) were forced in a greenhouse after each 100 hours of field chilling below 7.2°C during the 1969-70, 1970-71 and 1971-72 dormant seasons and bud break measured 21 days later. A chilling requirement of 500 hours was determined for ‘Desirable’ and ‘Mahan’, and 600 hours for Stuart.
