| Abstract:
Germination studies were performed on two varieties of pitaya (Stenocereus griseus (Haworth) Buxbaum) and jiotilla (Escontria chiotilla (Weber) with the further aim of reforestation. A viability test, with tetrazolium chloride at 1 %, was done on the seeds at 0 and three months after extraction from the fruits. Seeds, just removed from fruits (0 month old seeds), were germinated under both in light and dark, at temperatures of 18°C and 30°C and on the surface or covered with soil. Three month old seeds were germinated after been treated with water, sulphuric acid or gibberellic acid (GA3). In general, the best germination conditions at 0 months were: in the light, 30°C and on the surface. Viability level is maintained after three months but germination percentage decreased. The highest germination percentage at three months was shown by jiotilla under GA3. | |
