本试验以黄瓜‘新泰密刺’和番茄‘D2856’为试材,研究在低温弱光(15℃/8℃,80μmol·m^(-2)·s^(-1),low temperature and low light,LL)下,丛枝菌根真菌(Arbuscular mycorrhizal fungi,AMF)和宛氏拟青霉(Paecilomyces variot...本试验以黄瓜‘新泰密刺’和番茄‘D2856’为试材,研究在低温弱光(15℃/8℃,80μmol·m^(-2)·s^(-1),low temperature and low light,LL)下,丛枝菌根真菌(Arbuscular mycorrhizal fungi,AMF)和宛氏拟青霉(Paecilomyces variotii)提取物智能聪(ZNC)对黄瓜和番茄幼苗生长及其抗氧化系统活性的影响。幼苗两叶一心时LL处理7 d,LL下根施基质重量比1%AMF(LL+AMF)和喷施10 mL 10 ng·mL^(-1) ZNC(LL+ZNC),以正常温光为对照(28℃/18℃,600μmol·m^(-2)·s^(-1),CK)。结果表明,与CK相比,LL显著降低黄瓜和番茄壮苗指数和根系活力,抑制植株生长,且黄瓜和番茄幼苗SOD、POD活性及可溶性糖和蛋白含量增加,说明LL引起植株膜脂过氧化。LL下施用AMF和ZNC显著提高黄瓜和番茄的可溶性糖含量以及POD和CAT活性。其中,LL下施用AMF和ZNC黄瓜的壮苗指数显著提高,较LL分别提高19.4%和11.1%;LL+AMF和LL+ZNC番茄幼苗根系活力及可溶性糖含量较LL分别提高22.7%、14.8%和31.9%、26.9%。综上所述,本试验条件下AMF和ZNC可通过提高黄瓜和番茄幼苗抗氧化酶活性以及渗透调节能力,减轻低温弱光造成的植株膜脂过氧化水平,进而缓解对黄瓜和番茄幼苗的生长抑制。展开更多

文摘The Bashu area was one of the most civilized agricultural areas in ancient China.Since the late Eastern Han Dynasty,it has been reputed as the“Land of Abundance”due to its abundant resources.Archaeological data show that the Shu area cultivated millet as early as the prehistoric period.The legend goes that Can Cong was the first ruler of the Shu area during the pre-Qin period,indicating that agricultural production at that time had made great progress compared with the prehistoric period.During this period,the agricultural pattern of the Shu area experienced profound changes,from dryland millet farming originating from the Western Sichuan Plateau to rice farming that is more suitable for Sichuan Basin,especially for the Chengdu Plain,where there are abundant rainfalls and high temperatures.Since then,rice farming has become a long-established farming tradition in the Shu area.The agricultural production tools and grain crop seeds unearthed from the Baodun site,where the archaeological remains of Can Cong Culture were discovered,show the prosperity of early agriculture in the Shu area.During the Baodun Culture period,the accelerated economic and social development in the Shu area promoted complicated and hierarchical changes in the social organization structure of settlements,which gradually evolved into early states.
