Effects of shading on growth, development and physiology of two golden camellia species origined in Guizhou Province
【Objective】To provide theoretical support for the cultivation, artificial pollination and natural regeneration in Camellia huana and C. liberofilamenta, the effects of shading on the growth, flowering habits and physiological indices of its cuttings seedlings were studied.【Method】Three-year-old cuttings were used as experimental material. Four shading treatments were set up with shading net, including 0% (CK), 30%, 60% and 90% shading. After 12 months, the seedling height, ground diameter, crown width, flower bud numbers, bud numbers, organic matter accumulation, chlorophyll and malondialdehyde (MDA) contents were measured.【Result】The seedling height, crown width, shoot numbers and leaf numbers were the highest under 60% shading, and the soluble sugar and MDA contents were the highest in CK for C. huana while the seedling height and shoot numbers were the highest in 60% shading for C. liberofilamenta. The ground diameter, leaf numbers, soluble sugar, soluble protein and MDA contents were the highest with 30% shading. The contents of chlorophyll a, chlorophyll b and carotenoids for two kinds of Camellia were higher under 90% shading. Under the same shading treatment, the soluble protein content of C. liberofilamenta was 3.3-6.2 times higher than that of C. huana. The blossom periods for C. huana and C. liberofilamenta were from January to March and from October to December respectively, and the full-blossom period was in November. Membership function analysis showed that the comprehensive ranking of each index score for two Camellia varieties under different shading treatments was the highest under 60% shading, the lowest in CK.【Conclusion】Shading treatment affected the growth, flower bud differentiation and physiological characteristics of two Camellia varieties. The 30%-60% shading treatments in C. huana and 60%-90% shading treatments in C. libtrofilamenta were more conducive to growth and development.
