英文摘要	Sunflower (Helianthus annuus L.) is moderately tolerant to salt and water stress, but its production can still be significantly and adversely affected by increases in these stressors as a result of the negative impacts of climate change on agricultural soil and crop productivity. The morphological and productivity (dry head weight, dry root weight, dry shoot weight, head diameter, whole seed weight, crude protein content, crude oil content, palmitic acid, stearic acid, oleic acid, linoleic acid, eicosanoic acid, 11-eicosenoic acid, homo-gamma-linolenic w6 acid, lignoceric acid and plant height) responses of modern sunflower germplasms to different levels of salt and drought stress under greenhouse and field conditions were investigated and analysed. Six germplasms were evaluated under three salt concentrations (0, 150 and 250 mM), and two germplasms were evaluated for drought response under three irrigation levels. Significant differences in the response of sunflower germplasms to water and salinity were detected. The same germplasms exhibited significant differences in response to water and salinity between the treatments, which also varied significantly between the germplasms for the same treatment. The irrigation level significantly influenced the amount of oil but not the crude protein or fatty acid composition. The results and information of this research can aid in selecting and improving sunflower productivity under adverse (i.e. saline and drought) conditions. Le tournesol (Helianthus annuus L.) est mod & eacute;r & eacute;ment tol & eacute;rant au stress salin et hydrique, mais sa production peut encore & ecirc;tre consid & eacute;rablement et n & eacute;gativement affect & eacute;e par l'augmentation de ces facteurs de stress en raison des effets n & eacute;gatifs du changement climatique sur les sols agricoles et la productivit & eacute; des cultures. Les r & eacute;ponses morphologiques et de productivit & eacute; (poids sec de la t & ecirc;te, poids sec des racines, poids sec des pousses, diam & egrave;tre de la t & ecirc;te, poids des graines enti & egrave;res, teneur en prot & eacute;ines brutes, teneur en huile brute, acide palmitique, acide st & eacute;arique, acide ol & eacute;ique, acide linol & eacute;ique, acide eicosano & iuml;que, acide 11-eicos & eacute;no & iuml;que, acide linol & eacute;nique w6 homogama, acide lignoc & eacute;rique et hauteur des plantes) des germoplasmes de tournesol modernes & agrave; diff & eacute;rents niveaux de sel et de stress de s & eacute;cheresse dans les conditions de serre et sur le terrain ont & eacute;t & eacute; & eacute;tudi & eacute;es et analys & eacute;es. Six germoplasmes ont & eacute;t & eacute; & eacute;valu & eacute;s dans le cadre de trois concentrations de sel (0, 150 et 250 mM), et deux germoplasmes ont & eacute;t & eacute; & eacute;valu & eacute;s en fonction de la r & eacute;ponse & agrave; la s & eacute;cheresse & agrave; trois niveaux d'irrigation.

Les m & ecirc;mes germoplasmes pr & eacute;sentaient des diff & eacute;rences significatives dans la r & eacute;ponse & agrave; l'eau et & agrave; la salinit & eacute; entre les traitements, qui variaient & eacute;galement de fa & ccedil;on significative entre les germoplasmes pour le m & ecirc;me traitement. Le niveau d'irrigation a eu une influence significative sur la quantit & eacute; d'huile, mais pas sur la composition en prot & eacute;ines brutes ou en acides gras. Les r & eacute;sultats et les informations de cette recherche peuvent aider & agrave; s & eacute;lectionner et & agrave; am & eacute;liorer la productivit & eacute; du tournesol dans des conditions d & eacute;favorables (c.-& agrave;-d., saline et s & eacute;cheresse).
