灰雁与两种家鹅染色体组型的比较——关于新疆鹅种源问题的探讨

众所周知,家鹅是由野生雁类驯化而来,通过长期的定向培育,形成了目前饲养的形态特征各异,生产性能不同的多个家鹅品种。郑作新(1982)指出,我国家鹅有两个种,一为鸿雁的变种,即Anser cygnoides orientalis(Linnaeus)另一为灰雁的变种,即A.anser domesticus Brisson。产于新疆北部伊犁谷地和准噶尔盆地西部塔城一带的新疆鹅,以其肉质细嫩、味道鲜美,耐粗饲而成为新疆主要家禽品种之一,豁眼鹅则是以产蛋多而著称的优良品种。它们的生产

陕西省关中夏玉米后期钻蛀性害虫的发生及不同玉米品种的抗虫性调查

为了明确陕西关中地区玉米生长后期钻蛀性害虫的为害情况及不同玉米品种的抗虫性,为玉米后期钻蛀性害虫的有效防治提供依据,在陕西关中选择5个具有代表性的县区进行调查,并且于2016年6月8-10日在阎良区种植21个玉米品种,观察不同品种的抗虫性。结果表明,陕西关中地区玉米生长后期钻蛀性害虫有亚洲玉米螟、棉铃虫和桃蛀螟3种,其所占比例因地而异。玉米后期钻蛀性害虫对21个供试玉米品种为害程度均较高,但不同品种之间受害程度有一定差异。     

The Sources of Wilt-resistance in the World Cotton Collection

Eight samples which were almost non-susceptible to wilt were isolated from the many forms in the world cotton collection. All of these forms are wild or semi-wild. Complex population varieties, especially those with varieties of Gossypium barbadense as ancestors, are also considered to be a source of wilt-resistance. Diploid wild species may also be used in the creation of wilt-resistant varieties.     

Elevated antioxidant response and induction of tau-class glutathione S-transferase after glyphosate treatment in Vigna radiata (L.) Wilczek

Glyphosate (N-(phosphonomethyl) glycine) is a broad-spectrum herbicide, acting on the shikimic acid pathway inhibiting 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS), thus obstructing the synthesis of tryptophan, phenylalanine, tyrosine and other secondary products. It has also been reported to generate oxidative stress which influences the antioxidant response of target plants. The effect of glyphosate application on total protein, CAT, POD and GST activities was investigated and elevated expression of the oxidative stress enzymes was obtained after glyphosate treatment.Tau-class GSTs are plant-specific, and are chiefly involved in xenobiotics and oxidative stress metabolisms. Many herbicides and safeners have been known to selectively induce tau-class GSTs in different plant species. Here we also report the induction of tau-class GSTs after glyphosate treatment in the seedling roots of two Vigna radiata varieties (PDM11 and PDM54). GSH-agarose affinity chromatography and mass spectrometry revealed that the tau-class GSTs induced in the two varieties were different; the tau-class GSTs present in the untreated controls were also different in the two varieties. The present study highlights the elevated antioxidant response, the induction of tau-class GST and the genotypic variation in the type of tau-GST in control and glyphosate treated varieties of V. radiata.     

Einfluss von mechanischen Ber��hrungsreizen auf das Wachstum von K��chenkr?utern im Topf

For a compact growth of many potted plants you often have to use chemical growth inhibitors. Various species of herbs tend to an undesirable extension growth too. In general, the use of chemical inhibitors is prohibited in the production of potted herbs. For several years at the State Horticultural College and Research Institute Heidelberg there is employed an alternative method of mechanical stimulation treatment for a compact growth of potted plants. The greatest reduction of elongation was obtained, when the plants were treated with breaks in the early morning. In 2009 and 2010, the employees of the trial station proofed the effect of mechanical stimulation (Thigmomorfogenesis) to a large assortment of organically produced potted herbs. Green and red varieties of basil, parsley, coriander, chervil, lemon balm (2009) and four different varieties of mint (2010) were stimulated with a machine one week after beginning culture continuously 108 times per day. Compared to the untreated plants all mechanically stimulated herb species and varieties showed a tendency or significantly reduced elongation growth and therefore more stability. Depending on species and varieties the quality of these plants was visibly improved.     

Determination of seedborne fungi and detection of aflatoxins in sudanese fenugreek seeds

Following incubation of fenugreek(Trigonella foenum- graecum L.) seeds on potato dextrose agar and moist filter papers at 28±2°C, 59 species and 11 varieties belonging to 21 genera of fungi were determined as seedborne in fenugreek crops. Among these isolates, 45 species and 9 varieties are new records for this crop; and two species are new to the mycoflora of Sudan:Aspergillus stellifer andEmericella variecolor. The genusAspergillus (15 species and 8 varieties) is the most prevalent, followed byDrechslera (3 species),Rhizopus (3 species),Alternaria andFusarium (6 species each),Emericella (4 species and 2 varieties)Cladosporium andPenicillium (4 species each),Chaetomium (3 species) andCurvularia (3 species and one variety). The remaining 11 genera displayed low level of infection. Of the common pathogens of fenugreek plants,Fusarium oxysporum (2.13%) was recovered from the seeds of this crop. Thin layer Chromatographic analysis of chloroform extracts of 13 seed samples showed that two samples were naturally contaminated with aflatoxins B₁, B₂, G₁ and G₂ (7.5–35.2 μg/kg). http://www.phytoparasitica.org posting Nov. 4, 2001.
