B Of the six basic media MS, MS1/2 (half-strength of MS salts and vitamins), WPM, DKW, B5 and SH, MS1/2 was the most proper one to induce somatic embryos. Somatic embryos generally regenerated directly from excised zygotic cotyledons. PGRs combination affected somatic embryogenesis significantly. Medium with NAA 1mg/L, TDZ 0.05mg/L, IBA 2—10mg/L combined with BA 10mg/L, or IBA 10mg/L integrated with BA 0-2mg/L gave the highest induction rate. Excised zygotic hypocotyls had the strongest potential to produce callus. Callus induction was also affected significantly by media and PGRs. The proper callus induction condition was MS1/2 medium containing NAA 1mg/L, IBA 10mg/L, BA 2-5mg/L and TDZ 0.05mg/L. Harvest period affect somatic embryogenesis significantly. Zygotic embryo explants collected from the end of July to the middle of August had strong potential to generate somatic embryos, when endosperm finished solidification, different parts of the embryos were completely formed, the size of embryos occupied about 2/3 of the embryo sac. Provided with optimized conditions, direct somatic embryogenesis rate can attain to 33. 68%, and callus induction rate of hypocotyls was up to 90.7%. Cytological observation on megasporogenesis and zygotic embryogenesis of Manchurian ash showed that the ovary was twicarpellum, twilocular with two ovules each loculus. The ovule was tenuinucellar and anatropous, with one megasporcocyte. The development of embryo sac is of the Polygoum type.

The positive expression both of p14ARF and mtp53 protein in NSCLC tissues were significantly different from that in nonmal lung tissues and tissues adjacent to the cancer (P.01).The expression of p14ARF protein was correlated with pathological degree（P＜0.01）,but it was uncorrelated with pathological staging,lymphaden metabasis and vessel invasion(P＞0.05).The expression of mtp53 protein was correlated with clinical pathology staging,pathological degree and vessel invasion(P＜0.05 or P＜0.01),but it was uncorrelated with lymphaden metabasis(P＞0.05).(2) The coexpression of p14ARF and mtp53 was 36.7％,their consistency was 38.8％,but the expression of p14ARF protein were negatively correlated with the expression of mtp53 protein(r=-0.3553,P＜0.001).Conclusion The results suggest that the decrease of p14ARF and the increase of mtp53 protein may play an important role in the genesis and development of NSCLC.
