摘要
在当今世界,化肥的使用已成为提高作物产量的必需品,但化肥会对环境、土壤质量和人类健康造成负面影响。因此,使用化肥替代品是当今时代的必然要求。植物生长促进真菌(PGPF)是替代化学肥料的最佳选择,可促进植物生长,提高作物产量,改善植物的养分供应。它们还能阻止植物病原体的生长,因此是一种生物控制剂。我们的研究旨在筛选和检验植物生长促进真菌对大麦作物的影响。我们从小麦根圈中分离出了七种真菌菌株。对分离的真菌菌株进行了体外植物生长促进特性筛选。其中,一个分离菌株 14F 对五种不同的植物生长促进性状均呈阳性。通过对 ITS 基因区进行扩增和测序,在分子水平上对该分离菌株进行了进一步鉴定,确定其为雷氏毛霉。将雷氏毛霉接种到大麦种子中,并分析其效果。与未接种的植株相比,观察到植株高度(根长和芽长)、植株重量(干重和湿重)显著增加。这种毛霉菌株可成为可持续农业的理想生物肥料。
Isolation and Inoculation Effect of Trichoderma reesei on Growth and Yield of Barley
In today’s world, usage of chemical fertilizers has become necessity for betterment of crop yield; however they have negative impact on the environment, quality of soil and human health. Therefore, involvement of substitute for chemical fertilizers is an essential requirement of present time. Plant growth promoting fungi (PGPF) serves as a best alternative in place of chemicals to enhance plant growth, crop productivity and improve nutrients availability for plants. They also show an involvement in ceasing growth of plant pathogens, hence acting as a bio control agent. The aim of our study is to screen and examine plant growth promoting fungi effect on barley crop. A total seven fungal strains were isolated from wheat rhizosphere. The isolated fungal strains were screened for their In vitro plant growth promotional traits. Among total, one isolate 14F found positive for five different plant growth promoting traits. This isolate was further identified at molecular level by amplification and sequencing of ITS gene region and was identified as Trichoderma reesei. Trichoderma reesei was inoculated with barley seeds and its effects were analyzed. Significant increase was observed in terms of plant height (root length and shoot length), plant weight (Dry and wet weight) as compared to un-inoculated plants. This Trichoderma strain could become a fantastic bio-fertilizer for sustainable agriculture.
