  Meteorological Factors on Freezing Injury of Amygdalus communis During Overwintering in Yingjisha of Xinjiang Kerimu ABASI, Nuerpatiman MAIMAITIREYIM, MENG Fanxue, CHEN Gang, Patiman ABUDUAINI Journal of Agriculture    2022, 12 (2): 31-35.   DOI: 10.11923/j.issn.2095-4050.cjas20191100279 Abstract + (1981)    HTML (712)    PDF (1186KB) (9983)       Knowledge map    By using the basic meteorological data of 2001 to 2019 from Yingjisha national meteorological observing station and the phenological observation data and freezing injury data, the freezing rate of flower bud and yield of Amygdalus communis were analyzed. Combined with mathematical statistics, the meteorological factors causing frozen flower bud during overwintering period of Amygdalus communis in Yingjisha were studied. The results showed that the lowest air temperature in winter and its lasting days, the lowest land surface temperature and frozen earth depth caused the freezing of Amygdalus communis buds, but there was no obvious impact of the maximum snow depth of winter and its lasting days and winter precipitation. When the lowest temperature was -23℃ to -18℃, its lasting days and the lowest land surface temperature were the main factors causing frozen flower buds.

  Death causes of Chinese pine (Pimus tabulaeformis) at the Tiananmen Square in spring 2010 and technical measures null Journal of Agriculture    2011, 1 (xb1): 44-49.   DOI: 10.11924/j.issn.2095-4050.2011-xb0027 Abstract + (5809)       PDF (10870KB) (6040)       Knowledge map    In order to explore some causes why pine needles turned yellow and many Chinese pine trees gradually died at Tiananmen Square in Beijing, China in spring 2010, a field investigation was conducted on the external morphology and the root characteristics of Chinese pine, and meanwhile soil physical and chemical properties and site conditions were also investigated and analyzed. It is found that for most of Chinese pines trees, the pine needles of their whole plants turned yellow, their fine roots withered and shriveled, and mycorhiza were rotten and died. The high salt content was found in surface soils, and the roots absorbed the large amounts of salts and lost the function of absorbing water and nutrients, which led to the emergence of yellow pine needles and the death of the whole plant. Some factors (such as small growth space, high soil density, poor soil ventilation and heat radiation) were not in favour of normal growth of Chinese pine. Moreover, a great amount of snow-melting agent was applied around Chinese pine at the Tiananmen Square after snow in winter 2009, which was a direct cause leading to the death of Chinese pine. In order to protect the achievement in afforestation and visual effects, the corresponding technical measures and suggestions were presented to prevent the hazards of snow-melting agent and to overcome the current status of adverse site conditions.

Because it contains many steps, high background, unspecific bands, streaking and so on are the common problems in Western blot, which will influence the subsequent detection and quantitation of protein. To establish the best experiment condition for detection of protein expression in rabbit artery, VCAM-1(vascular cell adhension molecule-1) was detected. A rapid, specific and sensitive procedure has been successfully established, through optimizing several conditions which include SDS-PAGE, antibody dilution, temperature and time for antibody incubation, detection methods and so on. Also, three kinds of detection methods were used which contain DAB, enhanced chemilluminescence (ECL) with exposure captured on X-ray film or with cooled charged-coupled device (CCD) cameras. The sensitivity of three methods was compared. The results indicated that ECL has sensitivity 2-10 times that of DAB, and CCD cameras have 4 times sensitivity of X-ray and a more precise procedure. So, ECL-CCD cameras is a promising detection method of Western blot.
