  6. The seeds damaged by voles due to oil attraction ? • Germinnated seed — no attraction for voles?

  7. MATERILS Cg 1 JM a JM b Different germinating stages of C.grijsii seeds used in oil-content test

  8. METHODS • Oil Content TestSoxhlet method. • StatisticsAnalysis of Variance (ANOVA) for the whole test; • t test for the significant difference between oil contents of seed /seedling at every two stages.

  9. RESULTS Oil content of C. grijsii seed /seedling at different germinating stages (%)* * Different letter mark means significant difference at level P< 0.05.

  10. SUMMARIZATION • Rich fragrant edible oil were attractive for voles. • Using germinated seeds with a root length beyond 3 cm was successful for survival in nursery. • Comparing the oil content of dormant seed with germinated seed at different stages showed that there is approximately 1/3 decrease of the oil from seeds at dormant stage to that at germinating stage 1,2, and 3 .The difference in between is of statistical significance at level P<0.05. • Has the significant decreasing of the oil content during the seed germination made the seeds losing attraction for voles? • Are there some other substances changing that protects the seeds from voles’ aggression? • Additional successive and detailed studies are required to reveal the exact reason.
