为建立优异软枣猕猴桃雄株综合评价体系,初步筛选保存的长白山山脉帽儿山区野生雄株软枣猕猴桃资源,以25份雄性软枣猕猴桃为调查对象,参考《猕猴桃种质资源描述规范和数据标准》的调查方法对全部资源进行了生物学性状的观察和测量。结果表明,一年生枝阳面色泽以褐色系列为主,皮孔多为浅黄色或灰白色的小皮孔,皮孔形状则以短梭形和椭圆形为主,且多在枝条上排列较为密集。一年生枝横截面表型以圆形和椭圆形为主,芽座多为小芽座,枝条叶痕较多表现为浅,m17-35的一年生枝节间长度最长,为3.7 cm,m17-16节间长度最小,为1.6 cm。成叶与幼叶在形状及叶基形状上具有一定差异,幼叶均为卵圆形,但部分资源的叶片发育为阔卵形,幼叶叶基为楔形和圆形,成叶叶基为心形和圆形。全部资源成叶叶片均被白色刚毛,多双面被毛,其中5份资源背面无毛。成叶叶片长度在8.3~11.8 cm,平均值为9.9 cm。叶片宽度在5.3~6.8 cm,平均值为6.2 cm。其中m17-40的叶片最大,叶片长度和宽度分别为11.8 cm和6.8 cm。全部资源的叶柄长度在2.6~3.9 cm,平均长度为3.2 cm,叶柄直径在1.7~2.5 mm,平均值为2.1 mm。综合来看m17-1的叶柄最长最粗,分别为3.9 cm和2.5 mm。

对高校思想政治教育来说,中国优秀传统文化是一项非常重要的思想文化资源。然而,如何将中国优秀传统文化有效地运用到高校思想政治教育中去,使中国优秀传统文化与高校思想政治教育实现深度融合,这仍然是当下高校思想政治教育工作者们需要不断探索的课题。纵观近十多年来的相关研究,多集中在宏观理论层面研究融入的意义、困境和路径、概括中国传统文化、撷取特色文化等三个方面,目前的研究还存在遵循意义、困境和路径研究的固定模式、两跨专业教师稀缺、较少涉及到高校思想政治教育的具体课程等问题。从对当前研究动态的批判和反思来看,关于中国优秀传统文化融入高校思想政治教育的研究还面临着诸多问题需要去研究、去解决,其未来的研究之路还很长。
