| Popis: | Salsola vermiculata L. Syn. Caroxylon villosum (Delile) Akhani & Roalson (Chenopodiaceae) is a perennial small woody species widely distributed in arid zones of Middle East and North Africa (MENA) region. It is one of the promising pastoral species for the rehabilitation of arid rangelands in Mororcco. The objectives of this study were to determine the effects of temperature and duration of seed storage on the germination of Salsola vermiculata, to determine the optimal transplant age of Salsola vermiculata seedlings and to compare the production of two varieties of Salsola vermiculata (villosa and brevifolia). The germination tests were carried out in a germination incubator at the laboratory of the Errachidia experimental station. 12 temperature regimes and three durations of seed storage were tested. For transplantation, comparisons were made between villosa variety seedlings of 1.5 months, 4 months and 8 months. In addition, the production the 8-month-old seedlings of the two varieties of Salsola vermiculata (var. villosa and var. brevifolia) were compared. The percentage of germination and the germination rate were very high for several temperature regimes, except for the high temperatures. In addition, it decreased very significantly with the storage duration of the seeds. Regarding the age of seedling transplants, the eight-month-old seedlings were the best in terms of production and growth rate. In addition, the villosa variety produced very significantly more phytomass than the local variety brevifolia. African and Mediterranean Agricultural Journal - Al Awamia, No 128 (2020) |
