玉米穗、茎腐病病原学的相互关系研究表明：其优势致病菌禾谷镰孢菌和串珠镰抱菌均可交互侵染引起这两种病害，并且能从植株的外侧和内部由基部向穗部传染，初步证实引起穗腐病的镰孢菌是来自茎腐病的镰孢菌。

The hematopoietic system was reconstituted and the chimaeras were formed.The results showed that hematopoietic stem cells coming from ES-D3 cells could reconstitute the mice following high dose chemotherapy in vivo. This research offers theories for HSCs induced from embryonic stem cells supporting the high dose chemotherapy of cancer.

将鉴定的造血干细胞移植入大剂量化疗的C57BL/6鼠，观察造血重建功能并证明有嵌合体形成，从体内实验方面证实了ES-D3细胞来源的造血干/祖细胞移植能够重建接受大剂量化疗小鼠的造血功能，为胚胎干细胞来源的造血干细胞支持大剂量化疗提供了实验依据。

It was typically indirect effect that the following variations induced in the progenies of endosperms implanted by heavy ion beams were discovered. 1 In comparison with control, there were very high differences in biological trait, anti-oxidation enzyme activity, MDA content and protein content, chromosome aberration rate and micro-nucleus rate in M1 generation. 2 Shorter stem variants and purple stem mutants were analyzed by RAPD and AFLP. The analytic results showed that the sequences of their DNA were changed, so those variations were not physiological damage only. And there were differences among M2 generation plants of the same sort of variants or mutants, it was indicated that M2 generation may be in disjunction.
