| 摘 要： | 研究旨在筛选适宜陕北榆林地区种植的优质沙棘种质资源,将‘实优一号’、‘深秋红’、中国沙棘、‘北欧一号’、‘无刺大果’5个沙棘品种引种到榆林地区,待生长初期结束,测定不同时期的农艺性状与生理指标,通过综合评价函数法和隶属函数法分别对不同沙棘品种的农艺性状与抗旱性进行综合评价。引种至榆林地区的沙棘品种存活率以‘深秋红’两年生最高,达99.02%;通过农艺性状分析得出,移栽至榆林地区的5个沙棘品种在株高、冠幅及地径粗生长量上除中国沙棘外均有所增长;通过对比生理指标结果得出,5个沙棘品种各指标均有不同幅度的变化。移栽后除‘无刺大果’以外沙棘的丙二醛含量从初期到末期均表现为先增后减的趋势;在超氧化物歧化酶含量变化上,末期的‘无刺大果’的超氧化物歧化酶含量显著高于除中国沙棘外的品种(P<0.05);从过氧化物酶含量变化上可以看出,除‘实优一号’与‘无刺大果’外,其余品种的过氧化物酶含量有所增加;在游离脯氨酸含量变化上,‘实优一号’、‘无刺大果’的游离脯氨酸增长量最大,分别为24.6、23.65 μg/g;在叶绿素含量比较中,‘北欧一号’与中国沙棘的叶绿素含量最高。通过存活率、农艺性状评价及抗旱性评价综合分析得出,两年生‘深秋红’是最适宜引种至陕北榆林地区的优质沙棘树种。

| Abstract: | To screen high quality Hippophae rhamnoides germplasm resources suitable for planting in Yulin of northern Shaanxi, five H. rhamnoides varieties, ‘Shiyou No.1’, ‘Shenqiuhong’, H. rhamnoides subsp. sinensis, ‘Nordic No.1’ and ‘Wuci Daguo’, were introduced to the area. At the end of the initial growth stage, the agronomic characters and physiological indexes at different growth stages were measured, the agronomic characters and drought resistance of different H. rhamnoides varieties were evaluated by comprehensive evaluation function method and subordinate function method. The survival rate of ‘Shenqiuhong’ among H. rhamnoides varieties introduced to Yulin was 99.02%, which was the highest. Through the analysis of agronomic characters, the growth of plant height, crown width and ground diameter of the five H. rhamnoides varieties transplanted to Yulin increased except H. rhamnoides subsp. sinensis. By comparing the physiological indexes, the results showed that the indexes of five H. rhamnoides varieties had different changes. After transplanting, the MDA content of H. rhamnoides increased first and then decreased from the beginning to the end, except the ‘Wuci Daguo’. In the change of superoxide dismutase content, the content of superoxide dismutase content of ‘Wuci Daguo’ in the late fruit was significantly higher than that in other varieties except H. rhamnoides subsp. sinensis (P<0.05). It can be seen from the change of peroxidase content that the peroxidase content of other varieties increased except ‘Shiyou No.1’ and ‘Wuci Daguo’. In the change of free proline content, ‘Shiyou No.1’ and ‘Wuci Daguo’ had the largest increase in free proline content, which was 24.6 and 23.65 μg/g, respectively. In the comparison of chlorophyll content, ‘Nordic No.1’ and H. rhamnoides subsp. sinensis had the highest chlorophyll content. Based on the comprehensive analysis of the survival rate, agronomic traits and drought resistance evaluation, it is concluded that the biennial ‘Shenqiuhong’ is the most suitable high-quality H. rhamnoides varieties for introducing to Yulin of northern Shaanxi. |
