《周易》中的“马”释     

徐秋林 《娄底师专学报》2009,(6):94-96

《周易》以＂远取诸物,近取诸身＂的方式来＂假物＂阐明我国生民累积生成的生存智慧。而马则因在生民农业生产、交通运输和军事活动中发挥过不可替代的作用,成为《周易》时代的＂假象＂之物,马因之成为意象。在该书中,马意象具有勇猛刚健、明理柔顺两种内涵。这两种内涵在尚＂易＂的动态循环中统一。  相似文献   

《文心雕龙》之“风骨”置喙     

顾卫国 《南宁师范高等专科学校学报》2009,26(3):28-31

关于＂风骨＂,历代专家、学者众说纷纭,是一个很难诠释清楚的概念。立足《文心雕龙》之《风骨》篇,笔者认为刘勰的＂风＂＂骨＂均指语言而说,情感说或内容说是后人敷衍的结果;＂风＂是语言的简洁精要,＂骨＂是语言的质朴刚健,＂风骨＂是二者整合后对语言的总体要求。  相似文献

Proteomic analysis of seed germination under salt stress in soybeans     

Xu XY  Fan R  Zheng R  Li CM  Yu DY 《Journal of Zhejiang University. Science. B》2011,12(7):507-517

Soybean (Glycine max (L.) Merrill) is a salt-sensitive crop, and its production is severely affected by saline soils. Therefore, the response of soybean seeds to salt stress during germination was investigated at both physiological and proteomic levels. The salt-tolerant cultivar Lee68 and salt-sensitive cultivar N2899 were exposed to 100 mmol/L NaCl until radicle protrusion from the seed coat. In both cultivars, the final germination percentage was not affected by salt, but the mean germination times of Lee68 and N2899 were delayed by 0.3 and 1.0 d, respectively, compared with controls. In response to salt stress, the abscisic acid content increased, and gibberellic acid (GA₁₊₃) and isopentenyladenosine decreased. Indole-3-acetic acid increased in Lee68, but remained unchanged in N2899. The proteins extracted from germinated seeds were separated using two-dimensional gel electrophoresis (2-DE), followed by Coomassie brilliant blue G-250 staining. About 350 protein spots from 2-DE gels of pH range 3 to 10 and 650 spots from gels of pH range 4 to 7 were reproducibly resolved, of which 18 protein spots showed changes in abundance as a result of salt stress in both cultivars. After matrix-assisted laser desorption ionization-time of flight-mass spectroscopy (MALDI-TOF-MS) analysis of the differentially expressed proteins, the peptide mass fingerprint was searched against the soybean UniGene database and nine proteins were successfully identified. Ferritin and 20S proteasome subunit β-6 were up-regulated in both cultivars. Glyceraldehyde 3-phosphate dehydrogenase, glutathione S-transferase (GST) 9, GST 10, and seed maturation protein PM36 were down-regulated in Lee68 by salt, but still remained at a certain level. However, these proteins were present in lower levels in control N2899 and were up-regulated under salt stress. The results indicate that these proteins might have important roles in defense mechanisms against salt stress during soybean seed germination.  相似文献

Effects of pre-harvest chemical application on rice desiccation and seed quality     

Yong-qi HE  Jin-ping CHENG  Liang-feng LIU  Xiao-dan LI  Bin YANG  Hong-sheng ZHANG  Zhou-fei WANG 《Journal of Zhejiang University. Science. B》2015,16(10):813-823

Pre-harvest desiccation may increase the efficiency of seed production. Field studies were conducted to determine the effects of diquat, paraquat, and ethephon applications on grain moisture, grain weight, and seed germination of hybrid rice Yanliangyou 88 (Oryza sativa ssp. indica) and conventional rice Wuyunjing 7 (Oryza sativa ssp. japonica). In 2013, we tested 12 treatments applied at four weeks (Yanliangyou 88) and six weeks (Wuyunjing 7) after heading. Results showed that reductions in moisture content were significant two and four days after chemical application. Chemical applications had no adverse effects on 1000-grain weight, germination percentage, or germination index, but there were negative effects on the percentage of normal seedlings. Desiccation effects increased with increase in the period after application, while the effect of ethephon combined with diquat or paraquat on desiccation was limited compared with that of diquat or paraquat alone in a short period after application. In 2013, chemical applications reduced the moisture content by from 0.5% to 6.4%, the germination percentage by from 0% to 3.3%, and the percentage of normal seedlings by from 13.3% to 100.0%. Among the treatments, diquat applied at 120 g/ha resulted in effective desiccation with fewer negative effects on grain weight and seed germination in 2013 and 2014. Therefore, diquat may have potential as a pre-harvest chemical desiccation treatment for rice. These results may provide a basis for developing and implementing protocols for large scale field trials.  相似文献
