CLONING OF THE HYMENOCALLIS SALISB.

The aim of this work was to evaluate the use of scales and “patas” (rooted basal plates) as a complementary measure to the separation of daughter bulbs in Hymenocallis. It was found that both the scales and the basal plate were able to form bulbils in variable number and size per scale or bulb.
The scales formed bulbils at the basal end of veins while in the basal plates the bulbils appeared either between scales or on the upper part of the remaining scales.
When using rooted basal plates, it was necessary to eliminate its central part to avoid the reappearance of the dominant meristem.
Bulbils formed on the basal plates may be separated when the basal plate decomposes.
There was wide variation in the number of bulbils formed and their size as well as the posterior growth.
The quantitative relations found are illustrated with respective regressions.
The formation of daughter bulbs in a population of bulbs originating from seed gave a very wide variation in the number of daughter bulbs formed per mother bulb.
This finding may be of significance in the generation of clones with low daughter bulb formation, a characteristic desired in pot and balcony planting.
