Quality of Albizia hasslerii (Chodat) Burkart Seeds And Seedlings In Function of Provenance

Abstract

Seeds can alter the physiological potential, according to the phytogeographic distribution of the matrices, making it necessary to study different harvest sites. The objective of the work was to compare the physiological potential of Albizia hasslerii seeds harvested in different places and to determine their effect on the quality of seedlings. The seeds were obtained from fruits harvested at the beginning of the dehiscence process. The mass of a thousand seeds, germination, germination speed index, respiration rate and emergency speed index were evaluated, as well as the production of seedlings conducted with and without irrigation. The design used was completely randomized and randomized blocks. The results of the physiological potential of the seeds indicated that the origins could be grouped in two groups. It was concluded that the seeds of A. hasslerii were influenced by the origin of the seeds, as well as the potential for root regeneration of the seedlings of all origins.
