Seed Characteristics of Quercus Liaotungensis in Zhenwushan Forest Farm of National Forest Administration Bureau of Guandi Mountain in Shanxi Province
Mature Quercus liaotungensis seeds were collected from Zhenwushan Forest Farm of National Forest Administra-tion Bureau of Guandi Mountain in Shanxi Province.The seed characteristics were studied by measuring the weight,insect infestation,starch content and germination situation of Quercus liaotungensis seeds.The results showed that the single seed weight of Quercus liaotungensis in Zhenwushan Forest Farm was 0.24 g~2.07 g,with an average weight of 8.17 g for ten seeds and 86.56 g for one hundred seeds.The phenomenon of seed boredom was severe,with a boredom rate of 49.6%.Among them,the number of seeds with one borehole and the borehole located at the bottom was the most.The starch con-tent of the seeds was 12.99%,lower than that of Quercus liaotungensis seeds in Beijing.The seed germination situation was poor which the germination rate of complete seed was 3.13%,its germination potential was 12.5%and its germination in-dex was 0.25.
