福建省是我国花椰菜栽培历史最为悠久的地区之一,通过长期以来的引种、选育,福建的花椰菜形成两大品系:品质优良的福州松花型品系和高产的厦门硬花型品系。我们通过多年的选育,选育出品质介于厦门硬花型和福州松花型之间,产量接近厦门硬花型的花椰菜新品系19-1,近年来在福建省内示范推广,受到菜农的好评。但是由于福建地处亚热带气候区,每年春季雨水较多,花椰菜的留种难度大,且病害严重,我们根据多年的探讨,总结19刁的特征特性及其繁种技术如下。 一、品种主要特征特性 19-1品系是经过多年的单株隔离自交选育而成。该… 相似文献

极早熟葡萄90-1栽培经验总结 总被引:1,自引:0,他引:1
极早熟葡萄新品系90-1是洛阳农专果树教研室和偃师市唐僧寺果树品种试验基地的科技人员发现的乍娜葡萄品种的枝变。经多年转接扦插试验表明:该品系早熟性状稳定,6月下旬成熟,浆果发育期仅35天,比母株早熟30天左右。已在部分地区栽植。现根据90-1的品种特性并结合各地的试栽表现总结出该品系的配套栽培技术,供栽培者参考。1定植1.1园地选择90-1是从早熟葡萄品种乍娜中选育出的极早熟葡萄新品系,从萌芽至浆果成熟70天左右,浆果发育期仅35天。因前期需水量大,而且集中,所以一定要选择灌溉条件良好,土壤肥沃… 相似文献

AIM: To explore the effect of glucose-regulated protein 78 (GRP78) on the gastric carcinogenesis. METHODS: GPR78 expression patterns were examined in 34 specimens from gastric carcinoma patients using the immunohistochemistry (IHC) assay, and in 10 specimens using Western blotting analysis. In addition, the expression of GPR78 and cyclin D1 was detected in human gastric cancer cell lines SGC7901 and SGC7901-H78 (overexpressing GRP78) by Western blotting. RESULTS: By IHC assay, GRP78 was found to be highly expressed in the cytoplasm of gastric carcinomas as compared with the adjacent non-malignant tissues and corresponding normal tissues. GRP78 expression was positively correlated with gender and histological differentiation (P<0.05), but not with age, tumor stage and lymph node metastasis (P>0.05). Furthermore, we found that with the increased expression of GRP78 in SGC7901-H78 cells, the expression of cyclin D1 was also elevated. CONCLUSION: GRP78 might be a key player to be involved in the growth of gastric cancer. 相似文献

AIM: To explore the cardiomyocyte apoptosis induced by glucose-regulated protein 78/immunoglobulin heavy chain-binding protein (GRP78/BiP) in liver cirrhotic rats and its mechanism. METHODS: The liver cirrhotic rat model was established with multiple pathogenic factors, and sampled at the time points of 4 weeks, 6 weeks and 8 weeks. In experiment 1, the heart was collected and weighed, the thickness of the left ventricular wall was measured, and the ratios of the left ventricular wall thickness to the heart weight, and the heart weight to the body weight were calculated. In experiment 2, TUNEL was used to detect the apoptotic cardiomyocytes,and the protein levels of GRP78/BiP, CCAAT/enhancer-binding protein homologous protein/growth arrest and DNA damage-inducible protein 153 (CHOP/GADD153), caspase-12, nuclear factor-κB p65 (NF-κB p65) and B-cell lymphoma/leukemia-2 (Bcl-2) in the myocar-dium were detected by the method of immunohistochemistry. RESULTS: Compared with the normal myocardium, significant larger ratios of the left ventricular wall thickness to the heart weight and the heart weight to the body weight, a significant increase in the cardiomyocyte apoptosis, and a significant larger positive expression index of GRP78/BiP in the hearts 8 weeks after modeling were observed. The protein levels of CHOP/GADD153 and caspase-12 were gradually increased during the development of liver cirrhosis and were significantly increased at 8 weeks. The positive expression of NF-κB p65 and Bcl-2 showed consistent changes, and were markedly higher at 4 weeks than those at the other time points. The positive expression index of GRP78/BiP was positively correlated with the apoptotic index, and the levels of CHOP/GADD153 and caspase-12. The positive expression index of CHOP/GADD153 was negatively correlated with NF-κB p65 and Bcl-2. CONCLUSION: Elevated expression of GRP78/BiP may play a crucial role in the pathogenesis of liver cirrhotic cardio-myopathy mediated by endoplasmic reticulum stress. 相似文献
