摘要/Abstract

摘要： 以白鸡冠半同胞系F1代中25个新品系（11个黄白化新品系和14个绿叶新品系）为研究对象,观测茶树新梢生物量、生育期、叶片功能性状及光合性能,并分析两类茶树新品系之间的差异。结果表明：与母本白鸡冠相比,25个新品系新梢生物量均增加（15号和24号除外）,增幅为25.0%~106.25%,一芽三叶期提前（早、中生种比例达84%）;黄白化新品系叶片面积（LA）和比叶面积（SLA）明显增加,干物质含量（LDMC）则明显降低,其他指标变化不明显;绿叶新品系叶片面积（LA）和光合色素指标均明显增加,其他指标变化趋势不明显。此外,黄白化新品系叶片的LA和光合色素指标平均值显著低于绿叶新品系,而叶片的SLA、Chla/Chlb和Car/Chl比值平均值显著高于绿叶新品系。黄白化新品系叶绿素含量平均值仅为绿叶新品系的42.29%,但各项光合性能指标并未下降（只有3号和6号光合色素过低时显著下降）,说明该黄白化新品系在一定叶绿素含量范围内,单位叶绿素的光合效率较高,可能是对叶绿素含量低的一种生理补偿,有待进一步从生理和分子方面深入研究。

Abstract: With 25 tea strains as experimental material (14 albino tea strains and 14 green tea strains), the spring shoot biomass, growth stages, leaf functional and photosynthetic characteristics of the leaves were monitored, compares with both between difference new tea strains. The results showed that: comparing with female parents (Baijiguan), the spring shoot biomass were increased by 25.0%-106.25% (except 15 and 24) and the growth stages were advanced (early middle growth was 84%) in 25 new tea strains. The leaf area (LA) and specific leaf area (SLA) were significantly higher in albino tea strains than Baijiguan, but the leaf dry matter content (LDMC) had significant decrease, other indicators had no difference. The leaf area (LA) and photosynthetic pigments were significantly increased in green tea strains than in Baijiguan, other indicators were not pronounced. The average of LA and photosynthetic pigments in albino tea strains were significantly below the green tea strains, but the SLA, ratio of chlorophyll a and b (Chla/Chlb) and ratio of carotene and chlorophyll (Car/Chl) were significantly higher than the
