Randomly amplified polymorphic DNA (RAPD) markers and flow cytometry was used to confirm the occurrence of somatic hybrids. RAPD results with some primers surveyed indicated that one clone (A. chinensis + A. deliciosa) and four clones (A. chinensis + A. kolomikta) had RAPD banding patterns which combined the parental banding profiles. Ploidy levels of the (A. chinensis + A. deliciosa) clone were deduced as octoploid (2n = 8x), and the (A. chinensis + A. kolomikta) clones were tetraploid (2n = 4x), triploid (2n = 3x) or pentaploid (2n = 5x). The clones were confirmed as interspecific somatic hybrids in Actinidia.展开更多

[Method] Kiwi fruits were randomly taken as materials every 15 days since 20 days after full bloom （DAFB） to 170 DAFB until in mature stage. [Result] The results showed that during fruit development of ‘Ganmi 6＇, the total sugar soluble contents had a rising trend with relatively stable at 95 DAFB, then rose until har- vest with the maximum content （10.35%）. The titratable acid content showed a trend of increasing, then declining, then increase to the harvest content （1.10%）. From the sugar acid ratio, we can knew it decreased in 95 DAFB, then up to the max （9.38）. The changes of AsA contents showed double ‘S＇ shape, decreased af- ter the first increased rapidly, slightly increased and then decreased in the early harvest. [Conclusion] It provided a theoretical basis for scientific cultivation methods to explore the nutrients regulation.展开更多

[Method] A. arguta as the test material was processed at room temperature of 4 ℃ to determine the contents of chloro- phyll, water soluble sugar, water soluble protein, free proline, MDA, and antioxidant enzymes （POD activity, SOD activity, CAT activity） with the treatment at 25℃ as the control. [Results] The results indicated that with the prolonging of stress time, the content of chlorophyll was first increased and then decreased, and the content of MDA was increased; soluble sugar content of seedling leaf decreased gradually, while the soluble protein and proline content of seedling leaves were first increased and then decreased; the activities of SOD and POD were displayed a decline trend, meanwhile the activities of CAT was first increased and then decreased. [Conclu- sion] The various indicators showed that under low temperature stress, the chloro- phyll content decreased accompanied with membrane lipid peroxidation and MDA accumulation, and soluble sugar, soluble protein, free proline and antioxidant en- zymes play a protective role in different degrees.展开更多
