摘要:
]对杂交选育的坛紫菜新品系(WO144-3)的生长性状、耐高温性能、叶绿素含量、藻胆蛋白含量等指标进行了测定,并与一个野生型品系(WT)进行了对比分析。结果表明:1)经过20 d培养,WO144-3品系叶状体长度从4 cm增加到138 cm,平均日增长率为17.59%,是WT品系的1.92倍;叶状体厚度为(17.41±0.33)μm,约为WT品系的70%。培养开始时,WO144-3品系长宽比约为WT品系的2倍,20 d后增加到5倍。但WO144-3品系的平均日增重率与WT品系没有显著差异。2)在30 ℃高水温培养10 d后,WO144-3品系叶状体的长度是WT品系的1.70倍;此外,高温处理对WO144-3品系的Fv/Fm没有显著影响,而WT品系的显著降低了59%。3)WO144-3品系的藻胆蛋白、藻红蛋白和藻蓝蛋白的含量分别为WT品系的2.05、2.74和1.42倍,但在叶绿素a和别藻蓝蛋白的含量上两品系没有显著差异。由此可得出:WO144-3是一个窄/薄叶品系,具有生长速度快、耐受高温胁迫、藻胆蛋白含量高等优点,具备应用于生产的潜力。
Abstract:
Trait analysis is the core work of Pyropia haitanensis breeding.Therefore,the growth rate,high temperature resistance,chlorophyll and phycobiliprotein contents of the hybridselected strain of P.haitanensis(WO144-3) were measured in this study and compared with a wild-type strain(WT).The results suggested that:1) After 20 days of culture,the length of thalli of WO144-3 strain increased from 4 cm to 138 cm;the thallus thickness was (17.41±0.33) μm,which was about 70% of that of WT strain.The average daily growth rate was 17.59%,which was 1.92 times that of WT.At the beginning of the incubation,the thallus length/width ratio of the WO144-3 strain was about twice that of the WT strain,increasing to 5 times after 20 d.But no significant difference was found between WO144-3 and WT on the average daily weight rate.2) The thalli length of WO144-3 strain was 1.70 times that of WT strain after cultured with high temperature at 30 ℃ for 10 days to simulate high temperature stress.In addition,the high temperature had no significant effect on the Fv/Fm of WO144 -3,but decreased the Fv/Fm of WT by 59%.3) The contents of phycobiliprotein,phycoerythrin and phycocyanin of WO144-3 strain were 2.05,2.74 and 1.42 times those of WT strain,respectively.There were no significant differences between WO144-3 and WT on chlorophyll a and allophycocyanin contents.The above results indicated that WO144-3 was a narrow-leaf strain/thin thalli strain with the advantages of rapid growth,tolerance to high temperature stress and high content of phycobiliprotein,and had the potential to be used in aquaculture
