Abstract

The aim of this study was to evaluate the impact of cyanobacteria as a soil inoculant for cultivation of the medicinal plant, Allium sativum. Cyanobacterial strains isolated from the medicinal plant field were cultured in BG11/BG11° medium. Three cyanobacterial isolates, Nostoc sp. HNBGU 006 (NS-TGS), Pseudanabaena biceps (PaS-TGiS), Chroococcus turgidus (CS-TTS), were selected for in-vitro assays. Seedling growth assays were performed with A. sativum and Raphanus sativus seeds primed with different concentration of aqueous extracts prepared from these isolates. Live cell suspension of the selected cyanobacterium, NS-TGS, was inoculated in pot soil to observe the effect of cyanobacterization on growth of A. sativum. Maximum enhancement in all the growth parameters was exhibited by 1% aqueous extract of NS-TGS in comparison to control. The result of NS-TGS inoculation in pot soil revealed an increase of 54.92 % in root length, 31.28 % in shoot length, 112 % in dry weight and 50.33 % in yield. An enhancement of 84.28% in the allicin content was also recorded in cloves grown in treated soil as compared to control. There was significant enhancement in soil and leaf chlorophyll as well as soil potassium content with the highest recorded in the treatment BSI (before sowing inoculation) + ASI (after sowing inoculation). This study provides an insight to the cyanobacterization of soil with NS-TGS for the cultivation of A. sativum herb and is consistent with the sustainable agriculture approach.

接种 Nostoc 对药用植物薤白产量和质量的影响

本研究旨在评估蓝藻作为土壤接种剂对药用植物薤白栽培的影响。在 BG11/BG11° 培养基中培养了从药用植物田中分离出的蓝藻菌株。选择了三种蓝藻分离菌株：Nostoc sp. HNBGU 006（NS-TGS）、Pseudanabaena biceps（PaS-TGiS）和 Chroococcus turgidus（CS-TTS）进行体外试验。用这些蓝藻分离物制备的不同浓度的水提取物对茄子和油菜种子进行了幼苗生长试验。将所选蓝藻 NS-TGS 的活细胞悬浮液接种到盆土中，观察蓝藻化对荠菜生长的影响。与对照组相比，1% 的 NS-TGS 水提取物对所有生长参数都有最大的促进作用。盆栽土壤中接种 NS-TGS 的结果显示，根长增加了 54.92%，芽长增加了 31.28%，干重增加了 112%，产量增加了 50.33%。与对照相比，在处理过的土壤中生长的丁香的大蒜素含量也增加了 84.28%。土壤和叶片中的叶绿素以及土壤中的钾含量都有明显提高，其中以 BSI（播种接种前）+ASI（播种接种后）处理的记录最高。这项研究为利用 NS-TGS 对土壤进行蓝藻化处理以栽培 A. sativum 草本植物提供了见解，符合可持续农业的理念。

期刊介绍： The Journal of Applied Phycology publishes work on the rapidly expanding subject of the commercial use of algae. The journal accepts submissions on fundamental research, development of techniques and practical applications in such areas as algal and cyanobacterial biotechnology and genetic engineering, tissues culture, culture collections, commercially useful micro-algae and their products, mariculture, algalization and soil fertility, pollution and fouling, monitoring, toxicity tests, toxic compounds, antibiotics and other biologically active compounds. Each issue of the Journal of Applied Phycology also includes a short section for brief notes and general information on new products, patents and company news.
