•Germinnated seed — no attraction for voles?

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.

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 germ
inated 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.
