The Efficacy of Salicylic and Acetylsalicylic Acids in the Protection of Fibrous Flax Against Drought Stress

摘要

Field experiments in years 2010 and 2011 aimed at assessing of the usefulness of salicylic (SA) and acetylsalicylic (ASA) acids in the cultivation of fiber flax. The aim of the study was to improve plant resistance to abiotic stresses (soil water deficit, high air temperature). SA and ASA are the active substances of the bio-products UP 208-200 SL and IWN-11. These experimental bio-producls were applied at the beginning of the flax rapid growth phase (BBCH 32 - plant height 18-20 cm) in doses of 1.0 and 2.0 L ha~(-1). The best results in increasing flax resistance to soil water deficit were obtained on Luvisols soil after the application of IWN- 11 (ASA) in the dose of 1.0 L ha~(-1).%在2010年和2011年的田间试验，旨在评估的水杨酸( SA)和乙酰基酸(ASA) 的种植亚麻的实用性。这项研究的目的是提高植物的耐非生物胁 迫（土壤水分亏缺，高风温）。SA以及ASA UP208-200 SL和IWN-11的生物制品的活性物质。这些实验的生物制品施加在1.0升公顷-1和2.0 L公顷-1剂量的亚 麻快速增长阶段（BBCH32-株高18-20厘米）的开头。在提高亚麻耐土壤水分亏 缺后的应用IWN-11(ASA)的1.0升HA-1的剂量，其在淋溶土上得到了最好 的结果。
