 หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Drought Recovery and Grain Yield Potential
of Rice after Chitosan Application) ผู้เขียน: Suchada Boonlertnirun,  ดร.เอ็จ สโรบล, ศาสตราจารย์ , Sawit Meechoui, นางอิสรา สุขสถาน, รองศาสตราจารย์ สื่อสิ่งพิมพ์:pdf AbstractChitosan is a biopolymer applied to plants in order to increase the key enzymes related to the closure of the plant’s stomata resulting in reduction of water loss. The aim of this experiment was to determine the effect of chitosan on drought recovery and grain yield of rice under drought conditions. The experimental design was arranged in RCBD with four replications of five treatments: sufficient irrigation, drought without chitosan, chitosan applied before drought, chitosan applied during drought and chitosan applied after drought. The experiment was conducted in a greenhouse at the Department of Plant Production Technology, Rajamangala University of Technology Suvarnabhumi, during April to August 2005.The results revealed that the treatment applied with chitosan before drought gave the highest yield and yield components and also showed good recovery. Furthermore, the percentage of damaged leaves was less than those of the other treatments. From this study, it is suggested that the severity of rice plants damaged from drought was reduced by chitosan application. |
