摘要/Abstract

摘要： 以蓝莓（Vaccinium spp.）品种‘明星’（‘Star’）一年生幼树为试验试材,用清水（CK处理）、50% Hoagland营养液（A处理）、100% Hoagland营养液（B处理）、150% Hoagland营养液（C处理）处理植株60 d,测定不同浓度Hoagland营养液对植株生长、叶绿素含量以及抗氧化系统的影响。结果表明,A处理、B处理、C处理下蓝莓幼树的株高和茎粗均高于CK处理,第15天C处理的株高、茎粗均最大,第45天和第60天A处理的株高、茎粗均最大,B处理的冠幅最大;第60天A处理、B处理、C处理下叶绿素a含量、叶绿素b含量、总叶绿素含量均高于CK处理;超氧阴离子产生速率随时间增加总体呈先上升后下降趋势,H₂O₂含量随时间增加整体呈上升趋势,第60天A处理的超氧阴离子产生速率、H₂O₂含量和MDA含量均最低;SOD活性随时间增加整体呈先上升后下降的趋势,第30天达到最高值;可溶性蛋白质和AsA含量在试验期内总体呈上升趋势,GSH含量呈先下降后上升趋势。

关键词: 蓝莓（Vaccinium spp.）, Hoagland营养液, 营养生长, 抗氧化系统

Abstract: One year old saplings of the blueberry variety ‘Star’ （Vaccinium spp.） were used as experimental materials. The plants were treated with water （control treatment）, 50% Hoagland nutrient solution （A treatment）, 100% Hoagland nutrient solution （B treatment）, and 150% Hoagland nutrient solution （C treatment） for 60 days. The effects of different concentrations of Hoagland nutrient solution on plant growth, chlorophyll content, and antioxidant system were measured.The results showed that under treatment A, B, and C, the plant height and stem diameter of blueberry saplings were higher than those of the control. On the 15th day, treatment C had the highest plant height and stem diameter, while on the 45th and 60th days, treatment A had the highest plant height and stem diameter, and treatment B had the highest crown width;on the 60th day, the chlorophyll a content, chlorophyll b content, and total chlorophyll content of treatment A, B, and C were higher than those of the control treatment;the production rate of superoxide anion showed an overall trend of first increasing and then decreasing with time, and the H₂O₂ content showed an overall upward trend with time. On the 60th day, the superoxide anion production rate, H₂O₂ content, and MDA content of treatment A were all the lowest;the SOD enzyme activity showed an overall trend of first increasing and then decreasing with time, reaching its highest value on the 30th day;the content of soluble protein and AsA showed an overall upward trend during the experimental period, while the content of GSH showed a first decrease and then an upward trend.

Key words: blueberry （Vaccinium spp.）, Hoagland nutrient solution, nutritional growth, antioxidant system
