摘要

Black locust (Robinia pseudoacacia) has worldwide economic and ecological importance and cultivated widely at the rate of three million hectare globally. A greenhouse experiment was carried out to investigate the role of seed provenance in growth andnutrient status of Robinia. Seeds from different geographical locations were planted in the same ecological conditions. After six months, all Robinia trees were harvested and separated into leaves, stems and roots. Element concentrations of P, S, K, Ca,Mg, Fe, Al, Mn and K in organic materials (leaves, stems and roots samples) were measured by ICP-AES. A significant difference was detected among seeds provenances of Robinia. regarding height (160-240 cm) and diameter (4.2-6.8 mm). Different Robinia seed provenances showed significant different concentrations of potassium (K) in leaves and calcium (Ca) in stems while no significant differences was observed in terms of other investigated nutrients.
