盐生植物是指能在50%或以上的海水浓度下完成其生命周期的植物。乙烯是植物种子萌发后期产生的一种天然激素，在调节种子萌发中起着重要作用。然而，其在盐胁迫下盐生植物种子休眠和萌发中的调控作用尚不清楚。在本章中，我们描述了两种乙烯供体乙烯利和1-氨基环丙烷-1-羧酸的应用方法，旨在研究乙烯在高盐度下对盐生植物salsa的代表性植物Suaeda种子萌发的影响。当考虑到盐的敏感性可能不同时，类似的方法可以应用于其他植物物种中乙烯和盐相互作用的研究。
Halophyte plant species are those that can finish their life cycle in the presence of 50% or more seawater concentration. Ethylene, as a natural plant hormone produced at later stages of seed germination, plays an important role in regulating seed germination. However, its regulatory role in seed dormancy and germination of halophyte plants under salt stress is still not well understood. In this chapter, we describe methods used for applications of two ethylene donors, ethephon and 1-aminocyclopropane-1-carboxylic acid, in studies aimed at examining the effects of ethylene on seed germination of a representative halophyte plant Suaeda salsa under high salinity. Similar approaches can be applied to the study of ethylene and salt interactions in other plant species, when taking into account that salt sensitivities may differ.
