The seasonal variations of allelopathic activity and allelopathic substances in Brachiaria brizantha
Botanical Studies - Tập 56 - Trang 1-7 - 2015
Ai Kobayashi, Hisashi Kato-Noguchi
Controlling weeds through allelopathy is one strategy to reduce dependency on synthetic herbicides. The plant shoots of the grass Brachiaria brizantha incorporated into the field soil were found to inhibit the growth of several plant species. We investigated the variations of allelopathic activity and allelopathic substances in B. brizantha h...... hiện toàn bộ
Impatiens pandurata (Balsaminaceae), a new species from Yunnan, China
Botanical Studies - Tập 56 - Trang 1-6 - 2015
Yun-Hong Tan, Yan-Nan Liu, Hong Jiang, Xin-Xin Zhu, Wei Zhang, Sheng-Xiang Yu
The species-rich genus Impatiens is mainly distributed throughout much of tropical Africa, India, southwest Asia, southern China and Japan. There are more than 270 species recorded in China, most of which are restricted to the southwest. An unknown species of Impatiens was collected from Yunnan, southwest China. Impatiens pandurata Y. H. Tan & S. X. Yu, a new species of...... hiện toàn bộ
Study on the effect of magnetic field treatment of newly isolated Paenibacillus sp.
Botanical Studies - Tập 56 Số 1 - 2015
Jie Li, YI Yan-li, Xiang Cheng, Zhang Dageng, Muhammad Irfan
Abstract Background Symbiotic nitrogen fixation in plants occurs in roots with the help of some bacteria which help in soil nitrogen fertility management. Isolation of significant environment friendly bacteria for nitrogen fixation is very important to enhance yield in plants. ...... hiện toàn bộ
Techniques for the collection, transportation, and isolation of orchid endophytes from afar: a case study from Madagascar
Botanical Studies - Tập 58 - Trang 1-10 - 2017
Lawrence W. Zettler, Landy Rajaovelona, Kazutomo Yokoya, Jonathan P. Kendon, Andrew L. Stice, Amanda E. Wood, Viswambharan Sarasan
Tropical orchids need more study with respect to their mycorrhizal associations. For researchers in distant countries who aspire to study these orchids augmenting their conservation, the great distances involved, coupled with limited funds, pose formidable challenges. These challenges are sometimes exacerbated by political unrest, delays in securing permits, unexpected hardships, and the risk that...... hiện toàn bộ
Management of potato brown rot disease using chemically synthesized CuO-NPs and MgO-NPs
Botanical Studies -
Amira Rabea, E. Naeem, Naglaa M. Balabel, Ghadir E. Daigham
Abstract Background Potatoes are a crucial vegetable crop in Egypt in terms of production and consumption. However, the potato industry suffers significant annual losses due to brown rot disease. This study aimed to suppress Ralstonia solanacearum (R. solanace...... hiện toàn bộ
Effects of abscisic acid and brassinolide on photosynthetic characteristics of Leymus chinensis from Songnen Plain grassland in Northeast China
Botanical Studies - Tập 54 - Trang 1-9 - 2013
Yong-Jun Hu, Lian-Xuan Shi, Wei Sun, Ji-Xun Guo
It has been well demonstrated that plant growth regulators have important functions in multiple physiological processes. ABA and BR play crucial roles in response of crops to stresses. Photosynthetic capacity of Leymus. chinensis treated by various concentrations of ABA and BR in combination was determined. Further more, the mechanisms of ABA and BR treatments and potential for recovery of saline-...... hiện toàn bộ
Functional characterization of NADPH-cytochrome P450 reductase and cinnamic acid 4-hydroxylase encoding genes from Scoparia dulcis L.
Botanical Studies - Tập 61 - Trang 1-11 - 2020
Yoshimi Yamamura, Ayaka Mabuchi
Most plant cytochrome P450 (P450) proteins need to be supplied with electrons from a redox partner, e.g. an NADPH-cytochrome P450 reductase (CPR), for the activation of oxygen molecules via heme. CPR is a flavoprotein with an N-terminal transmembrane domain, which transfers electrons from NADPH to the P450 via coenzymes flavin adenine dinucleotide and flavin mononucleotide. In this study, a novel ...... hiện toàn bộ
From leaf and branch into a flower: Magnolia tells the story
Botanical Studies - Tập 55 - Trang 1-12 - 2014
Wen-Zhe Liu, Khidir Hilu, Ya-Ling Wang
In the classical doctrines, Magnolia was frequently considered the archetype among flowering plants, and its conduplicate carpel with marginal placentation was assumed to be derived from a leaf-like organ bearing ovules along its margins. Although the robustness of this concept has been seriously questioned by advances in botanical research, especially the emergence of Magnolia deeper in the angio...... hiện toàn bộ
Antioxidant responses and photosynthetic behaviors of Kappaphycus alvarezii and Kappaphycus striatum (Rhodophyta, Solieriaceae) during low temperature stress
Botanical Studies - Tập 57 - Trang 1-9 - 2016
Hu Li, Jianguo Liu, Litao Zhang, Tong Pang
Kappaphycus are farmed in tropical countries as raw material for carrageenan, which is widely used in food industry. The sea area available for farming is one limiting factor in the production of seaweeds. Though cultivation is spreading into subtropical regions, the lower seawater temperature is an important problem encountered in subtropical regions for the farming of...... hiện toàn bộ
Physiology and metabonomics reveal differences in drought resistance among soybean varieties
Botanical Studies - Tập 63 - Trang 1-15 - 2022
Xiyue Wang, Yongping Li, Xiaojing Wang, Xiaomei Li, Shoukun Dong
The soybean is an important food crop worldwide. Drought during the first pod stage significantly affects soybean yield, and understanding the metabolomic and physiological changes in soybeans under drought stress is crucial. This study identified the differential metabolites in initial pod stage soybean leaves under polyethylene glycol-simulated drought stress, using ultra performance liquid chro...... hiện toàn bộ
