Abstract EN
Our objective was to evaluate the usefulness of the germination vs.
the X-ray test in determining the initial viability of seeds of five wild species (Moringa peregrina, Abrus precatorius, Arthrocnemum macrostachyum, Acacia ehrenbergiana and Acacia tortilis) from Saudi Arabia.
Usually several days were required to determine the viability of all five species via germination tests.
However, X-ray test will give immediate results on filled/viable seeds.
Seeds of all species, except Acacia ehrenbergiana and Acacia tortilis showed high viability in both germination (96–72% at 25/15 C, 94–70% at 35/25 C) and X-ray (100– 80 %) test.
Furthermore, there was a general agreement between the germination (19 %, 14 % at 25 / 15 C and 17 % and 12 % at 35 / 25 C) and X-ray (8 %, 4 %) tests in which seed viability of Acacia ehrenbergiana and Acacia tortilis was very low due to insect damaged embryo as shown in X-ray analysis.
Seeds of Abruspreca torius have physical dormancy, which was broken by scarification in concentrated sulfuric acid (10 min), and they exhibited high viability in both the germination (83 % at 25/15 C and 81% at 35/ 25 C) and X-ray (96 %) tests.
Most of the nongerminated seeds of the five species except those of Acacia ehrenbergiana and Acacia tortilis, were alive as judged by the tetrazolium test (TZ).
Thus, for the five species examined, the X-ray test was proved to be a good and rapid predictor of seed viability.
