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

Key words： Baijiguan half-sib teas; new albino tea strain; leaf functional; leaf photosynthetic
