    摘要:

    为探究陕西省汉中市境内秦岭南麓野生草莓的种类与分布情况,于2019年-2021年对秦岭南麓北纬32°49′46″到33°19′38″、东经106°09′23″到106°40′23″范围内的野生草莓资源进行了考察,考察地点涉及三个县的8个村,包括略阳县的孟家河村、王家庄村,宁强县的二里坝村、大树垭村,勉县的栗子坝村、李家沟村、秋齐垭村和头道河村。共收集野生草莓资源57份,通过植物学性状观察及倍性鉴定,分别属于3个种、2个类型,3个种分别是黄毛草莓(Fragaria nilgerrensis Schlect.)、中国草莓(F. chinensis Lozinsk.)、五叶草莓(F. pentaphylla Lozinsk.),其中五叶草莓为优势种;2个类型分别是五叶草莓粉果(F. pentaphylla, pink-fruited genotype)和五叶草莓红果(F. pentaphylla, red-fruited genotype)。野生草莓分布在海拔849~1352 m的山地、林下、溪边、路边、荒芜的耕田及岩壁上。本文还对收集资源的种类性状进行了详细描述,并对当地野生草莓资源保护与利用提出了建议。

    Abstract:

    To understand the genus Fragaria resources distributed in the south of Qinling Mountain in Hanzhong City, Shaanxi Province of China, the wild strawberries were surveyed during 2019-2021 (latitude, 32°49′46″ to 33°19′38″; longitude, 106°09′23″ to 106°40′23″). The investigation sites include eight villages of three counties (Mengjiahe Village and Wangjiazhuang Village in Lueyang County; Erliba Village and Dashuya Village in Ningqiang County; Liziba Village, Lijiagou Village, Qiuqiya Village and Toudaohe Village in Mi'an County). A total of 57 wild strawberry accessions were collected in this survey. These accessions were identified and classified into three Fragaria species including Fragaria nilgerrensis Schlect., F. chinensis Lozinsk. and F. pentaphylla Lozinsk. (white-fruited), and two types including F. pentaphylla pink-fruited genotype and F. pentaphylla red-fruited genotype through botanical character observation and ploidy identification. Among them, F. pentaphylla was found to be predominant in population. These wild strawberries were found in the vertical space of 849 - 1352 m above sea level, such as mountains, forests, streams, roadsides, barren fields and rock walls. We provided the characters of the collected Fragaria species in detail, and proposed the suggestions on the protection and utilization of local wild strawberry resources.
