Using Beta-Glucan Isolated from Helianthus annuus Infected by Sclerotinia sclerotiorum in Bakery
Sclerotinia sclerotiorum is a phytopathogenicfungus that attacks more than 400 plant species of Cock Rings them medicinal plant.In this study the extract obtained from basal stalk rot of Helianthus annuus L., attacked by S.sclerotiorum, was subjected to the analysis of FTIR to identify the presence of beta-glucan.FT-IR spectrum showed four ranges o
Development of a semi-automated volatile organic compounds (VOCs) sampling system for field asymmetric ion mobility spectrometry (FAIMS) analysis
In recent years, applications of volatile organic compounds (VOCs) sensing technologies such as field asymmetric-waveform ion-mobility spectrometry (FAIMS) system Cremas in agriculture have accelerated.FAIMS system for VOCs sensing is attractive as it offers high sensitivity, selectivity, real-time monitoring, and portability.However, the developme
Phylogenetic analyses place the monotypic Dryopolystichum within Lomariopsidaceae
The monotypic fern genus Dryopolystichum Copel.combines a unique assortment of characters that obscures its relationship to other ferns.Its thin-walled sporangium with a vertical and interrupted annulus, round sorus with peltate indusium, and petiole with several vascular bundles place it in suborder Polypodiineae, but more precise placement has el
