N.  aEffect of liquid nitrogen storage on Zizyphus joazeiro seeds.h[electronic resource]  c1995  aZizyphus joazeiro (Mart.) seeds - endocarps - tolerance to low temperature (-196øC) was investigated. Seeds were directly exposed to liquid nitrogen for 24 hours and thawed slowly at room temperature. Frozen seeds did not reveal sensivity to LN2 and showed higher gennination percentage and gennination rate than the control. The results suggest that the seeds are freezjng-tolerant and cryopreservation may be an altemative for their gennplasm conservation.  agermplasm  aseeds  astorage  aConservação  aGermoplasma  aSemente  aUmidade  aArmazenagem  aConservation  aConteudo  aJuazeiro  aLiquid nitrogen  aNitrogenio liquido  aPreservacao  aPreservation  aZizyphus joazeiro  tCryo-Lettersgv. 16, p. 85-90, 1995.
