Abstract
Seed conservation studies were conducted at the Germplasm Bank of the Faculty of Agronomy.
The most efficient method was to conserve the seed in Aluminium envelopes after desiccation under room conditions.
Seed germination after seeding showed values from 50 to 91% for A. satureioides, depending on the site of origin of the seed.
Seed from A. flaccida showed 65% germination after six months from seeding, with the seed kept at room conditions in a paper envelope.
Propagation of both species was made by sowing and cuttings in autumn and spring at the Experimental Station INIA Las Brujas, Canelones, Uruguay.
Propagation by cuttings in spring was not effective due to flowering in plants with little development that did not persist towards the second year.
Autumn cuttings showed poor rooting.
The most effective method was sowing in autumn.
Sowing in a field seedbed under plastic cover gave acceptable results.
Sowing was done on May 8, 1992, and in the field two distances between plants in the line were compared (30 and 45 cm). For A. satureioides, flower yields in the first harvest were 1218 and 920 kg/ha for the two plantation distances (30 and 45 cm respectively). For A. flaccida these yields were 320 and 134 kg/ha.
In the second year (harvested on March 30, 1994) these values were 540 and 897 kg/ha for A. satureioides and 5567 and 330 kg/ha for A. flaccida
