Seeds exhibit deep complex morpho-physiological dormancy.Low temperatures stimulate the breakdown of proteins into nitrogenous compounds and the formation of amino acids beneficial to embryo growth on synthetic media. Seeds are placed in cold moist stratification for 112 days.Germination occurs at 22D/17N C alternating temperature cycle. |
