Methods of stimulate the germination of Black Pine (Pinus Nigra) seeds

Abstract

The Black Pine (Pinus Nigra) belongs to the genus Pinus, which is one of the oldest genera. Today, more than 100 species belong to the genus Pinus, making it the richest genus of gymnosperms in the northern hemisphere. Black pine is used in plantations for its ornamental value, for timber production purposes, but especially in reclamation of degraded land.

The present work aims to apply methods to stimulate germination of black pine seeds. The study consists of using growth stimulators, following the germination faculty and germination capacity of Pinus Nigra (Black Pine) seeds under laboratory conditions, as well as seedling development.

Seeds of different origins were used, harvested from the counties of Bistrița-Năsăud, Cluj and Alba. The seeds were sown in containers with several wells and a single type of soil substrate (peat + perlite). Three variants were carried out for this method, in the first variant the seeds were soaked in distilled water, in the second variant the seeds were soaked in the growth stimulator Sprintene and for the third variant the seeds were soaked in the growth stimulator Atonik.
