Through all this test analyse Pathogenicity and Immunological status of ALV-J Inner Mongolia strain, the result showed the infected chickens began to have pathological change of Myelcytomatosis at 3-week: the main pathological changes of acidophile myelocyte were found in bone marrow and between cardiac muscle fibers,and there were many granules in the hyalotome.This kind of oncocyte proliferated in every tissue at different amount, but the cells that proliferated in bone marrow, cardiac muscle fiber, oarium were much more than other tissue, and they often developed neoplasma. At same condition,there were no abnormalty advent in control group, In immunological aspect: the increase of lymphokine and ANAE positive cells showed cell-mediated immunity was strengthend during antineoplastic infection; the emergence of ALV-J antibody of ELISA suggest there was humoral immunity exist at the same time.

结果显示：脾脏PCR检测结果表明1、2两实验组均有阳性病例出现，而对照组全部为阴性，说明实验鸡体内已有ALV-J内蒙株感染；接种病毒后3周龄开始出现骨髓细胞瘤病的病理变化：肝脏、脾脏有程度不同的肿大，镜下观察，骨髓内最早出现了与骨髓细胞相似、形态基本一致的大型圆形或椭圆形、胞核较大多为椭圆形、胞浆内含有大量嗜酸性圆形颗粒的髓细胞样瘤细胞增生，随后通过血流瘤细胞可转移到肝脏、心肌、卵巢或睾丸等组织并形成肿瘤性病灶，而对照组没有出现明显病变；免疫状态方面：以脾脏淋巴因子和ANAE阳性细胞增多说明细胞免疫在抗肿瘤感染过程中增强，ELISA检验实验鸡抗体出现阳性的结果表明同时也存在着体液免疫。

The result showed that the best time for sampling was 7 to 14 days after the first bud flowering on the main anthotaxy. The capacity of embryoid production varied significantly in different genotypes. Among them, twelve genotypes yield embryos successfully, which the rate could reach 71%. Genotype 102 was an ideal material for embryoid induction, and the frequency could reach 32.78 embryos per bud. Genotype that with a highest yield produced 546 times as many embryos as that with a lowest yield. The embryoid induction ability of normal bolting genotypes were higher than easy bolting and hard bolting genotypes.

Effects of gamma irradiation on shoot regeneration from leaf and bud growth in vitro of strawberry 1 The leaf was very sensitive to the gamma irradiation, and 'Toyonoka' was more sensitive than 'Akihime'. The LD50 (50% decrease of generation) of strawberry leaf was between 10 and 20 Gy. 2 Strawberry leaves were inoculated in vitro at 8 d-15 d after gamma rays irradiation, and the shoot regeneration rate from of 'Toyonoka' increased at 10 Gy and almost no difference from 20 Gy to 40 Gy. The positive effect dose for 'Akihime'.was from 10 Gy to 30 Gy, however, 40 Gy decreased shoot regeneration rate.
