MALVACEAE Corchorus tridens Improvement in germination % with pretreatments MALVACEAE Gossypium sp 38.82% germination after 13 years storage, low viability after time. Oil content? Climate cool and moist. Immature. Storage problems. MALVACEAE Grewia flava Improvement in germination % with pretreatments MALVACEAE Hibiscus aponeurus Low germination MALVACEAE Hibiscus cannabinus Low viability after time MALVACEAE Malva verticillata Low germination MALVACEAE Sida cordifolia Low germination MELIACEAE Turraea sp Low germination MELIACEAE Xylocarpus moluccensis Low germination MORACEAE Artocarpus altilis Very small seeds. Little success in germination testing, only achieved by root cuttings. MUSACEAE Musa sp Diploid seeds in non-fruit varieties. Germination testing difficult and slow, radicle takes long time to extend. Possible dormancy. MYROTHAMNACEAE Myrothamnus flabellifolius High germination % when tested or planted PANDANACEAE Pandanus kajui Low germination PEDALIACEAE Harpagophytum procumbens Improvement in germination % with pretreatments PEDALIACEAE Sesamum sp Low viability/dormancy? PEDALIACEAE Sesamum latifolium Low germination POACEAE Germination problems - dormancy in freshly harvested seed POACEAE Avena sp Germination problems - dormancy in freshly harvested seed. 67.14% germination after 12 years storage. POACEAE Eleusine coracana Low viability in initial tests. Orthodox. Immature seeds (harvest well matured seeds for storage). Maybe problems come from poor handling before and during storage with exception of wild relatives. POACEAE Eleusine indica Low germination POACEAE Hordeum vulgare Low germ in lab POACEAE Leptothrium senegalense Low germination POACEAE Oryza sp Orthodox. Low viability after storage. Immature seeds (harvest well matured seeds for storage). Maybe problems come from poor handling before and during storage with exception of wild relatives. Dormancy. POACEAE Oryza sativa Germination problems - pre soak and sand substrate, low viability in initial tests. Short lived species. POACEAE Pennisetum glaucum Orthodox. Low viability. Immature seeds (harvest well matured seeds for storage). Maybe problems come from poor handling before and during storage with exception of wild relatives.
POACEAE Sorghum bicolor Low viability in initial tests. Orthodox. Immature seeds (harvest well matured seeds for storage). Maybe problems come from poor handling before and during storage with exception of wild relatives POACEAE Zea mays Germination problems - coleoptile defects, low viability in initial tests RHAMNACEAE Berchemia discolor Improvement in germination % with pretreatments RUTACEAE Citrus sp Short term seed storage/root stock - low viability in initial tests. Now reclassified as recalcitrant. SAPINDACEAE Pappea capensis Improvement in germination % with pretreatments SAPOTACEAE Mimusops zeyheri Improvement in germination % with pretreatments SOLANACEAE Lycopersicon esculentus Possible slow germination if not extracted properly fermentation. SOLANACEAE Solanum sp Low viability post storage. Dormancy SOLANACEAE Solanum mammosum Short term seed storage/root stock - low viability post storage. SOLANACEAE Solanum melogena Germinate poorly at different times. Wild eggplant used as rootstock. SOLANACEAE Solanum villosum Low viability. Dormancy. TILIACEAE Corchorus sp Dormancy
