Study on the Rule of Nutrient Accumulation during the Development of Endosperm in Ginkgo biloba L.
[Objective] The rule of nutrient accumulation in the process of Ginkgo endosperm development was studied. [Method] Ginkgo variety-Fuzhi for the kernel usage being taken as experimental material, the change of nutrient during endosperm development was measured and analyzed. [Results] The results showed that the growth performance of the length, width of endosperm and the single-seed weight of Ginkgo was rapid from the full flowering stage to the 60th day after pollination in the process of Ginkgo growth and development, and then it became more and more gentle. The content of dry matter in endosperm was rapidly increased from the 50th day to the 141st day after pollination, and then, slightly decreased. The higher content of soluble sugar in endosperm appeared on the 50th day after pollination; then, declined; and finally, significantly increased from the 95th day after pollination to maturity stage. The content of starch in endosperm showed rapid upward trend from the 50th day after pollination, and then, the gentle increment of its content was starting from the 95th day after pollination. The content of starch in endosperm showed rapid upward trend from the 65lh day after pollination, and then, the gentle increment of its content was starting from the 110th day after pollination. [Conclusion] The rapid growth period of Ginkgo endosperm was from 65th-110th day after pollination.
