MALVACEAE Corchorus tridens Improvement in germination % with<br />
pretreatments<br />
MALVACEAE Gossypium sp 38.82% germination after 13 years <strong>storage</strong>,<br />
low viability after time. Oil content? Climate<br />
cool <strong>and</strong> moist. Immature. Storage problems.<br />
MALVACEAE Grewia flava Improvement in germination % with<br />
pretreatments<br />
MALVACEAE Hibiscus aponeurus Low germination<br />
MALVACEAE Hibiscus cannabinus Low viability after time<br />
MALVACEAE Malva verticillata Low germination<br />
MALVACEAE Sida cordifolia Low germination<br />
MELIACEAE Turraea sp Low germination<br />
MELIACEAE Xylocarpus moluccensis Low germination<br />
MORACEAE Artocarpus altilis Very small <strong>seeds</strong>. Little success in<br />
germination testing, only achieved by root<br />
cuttings.<br />
MUSACEAE Musa sp Diploid <strong>seeds</strong> in non-fruit varieties.<br />
Germination testing difficult <strong>and</strong> slow,<br />
radicle takes long time to extend. Possible<br />
dormancy.<br />
MYROTHAMNACEAE Myrothamnus flabellifolius High germination % when tested or planted<br />
PANDANACEAE P<strong>and</strong>anus kajui Low germination<br />
PEDALIACEAE Harpagophytum procumbens Improvement in germination % with<br />
pretreatments<br />
PEDALIACEAE Sesamum sp Low viability/dormancy?<br />
PEDALIACEAE Sesamum latifolium Low germination<br />
POACEAE<br />
Germination problems - dormancy in freshly<br />
harvested seed<br />
POACEAE Avena sp Germination problems - dormancy in freshly<br />
harvested seed. 67.14% germination after 12<br />
years <strong>storage</strong>.<br />
POACEAE Eleusine coracana Low viability in initial tests. Orthodox.<br />
Immature <strong>seeds</strong> (harvest well matured <strong>seeds</strong><br />
for <strong>storage</strong>). Maybe problems come from<br />
poor <strong>h<strong>and</strong>ling</strong> before <strong>and</strong> during <strong>storage</strong> with<br />
exception <strong>of</strong> wild relatives.<br />
POACEAE Eleusine indica Low germination<br />
POACEAE Hordeum vulgare Low germ in lab<br />
POACEAE Leptothrium senegalense Low germination<br />
POACEAE Oryza sp Orthodox. Low viability after <strong>storage</strong>.<br />
Immature <strong>seeds</strong> (harvest well matured <strong>seeds</strong><br />
for <strong>storage</strong>). Maybe problems come from<br />
poor <strong>h<strong>and</strong>ling</strong> before <strong>and</strong> during <strong>storage</strong> with<br />
exception <strong>of</strong> wild relatives. Dormancy.<br />
POACEAE Oryza sativa Germination problems - pre soak <strong>and</strong> s<strong>and</strong><br />
substrate, low viability in initial tests. Short<br />
lived species.<br />
POACEAE Pennisetum glaucum Orthodox. Low viability. Immature <strong>seeds</strong><br />
(harvest well matured <strong>seeds</strong> for <strong>storage</strong>).<br />
Maybe problems come from poor <strong>h<strong>and</strong>ling</strong><br />
before <strong>and</strong> during <strong>storage</strong> with exception <strong>of</strong><br />
wild relatives.
