“…The contents of K + and Na + were determined as Wei MDA content was measured according to the method described as Wei et al (2015). The leaf samples (0.3 g) were homogenized in 3 mL 5% (w/v) trichloroacetic acid (TCA) and the homogenate was centrifuged at 12,000×g for 10 min, then 2 mL of supernatant was The content of H 2 O 2 was measured following the method of Liu et al (2013).…”

“…Taking the example of salt stress, maintaining high levels of antioxidant substances (including enzymes and non-enzymes) is becoming the main physiological and biochemical means for strong salt tolerance in halophytes, or as potential selection criteria for improving salt tolerance of glycophytes by chemical regulation or molecular marker assistant breeding (Ashraf, 2009;Bose et al, 2014). Many studies have suggested that some exogenous substances that affect plant growth, such as salicylic acid (SA) in mustard (Syeed et al, 2011), H 2 O 2 in wheat (Li et al, 2011), spermine in cucumber (Shu et al, 2013), jasmonic acid (JA) in wheat (Qiu et al, 2014), and methanol in soybean (Wei et al, 2015) can enhance the tolerance to salt stress. Foliar spray, seed soaking and soil application of plant growth regulators are the commonly used methods for managing plant growth and development under normal or stressful conditions.…”

“…Therefore, seeking a simple and effective measure for improving soybean stress tolerance by chemical regulation is both very meaningful in theory and necessary in practice. In our earlier works, measures such as seed soaking by soybean isoflavones (Wu et al, 2011;Tian et al, 2014) and foliar spraying of methanol (Wei et al, 2015) The photoperiod was about 14 h/10 h (day/night).…”

Dihydroporphyrin iron (III) chelates (also known as DHFe) have a role in plant growth regulation under normal and stressful conditions. In the present study, using Glycine max cultivars Jackson (the salt-sensitive) and Lee68 (the salt-tolerant) as the experimental materials, the physiological and molecular events contributing to the ameliorative effects of foliar DHFe spray on seedling growth; leaf photosynthetic parameters; reactive oxygen species (ROS) content; antioxidant enzyme activity; Na + , K +, and Clcontents; and seed traits of soybean plants under control or salt-stressed conditions were investigated. The results showed that foliar spraying DHFe solution on soybean seedlings under NaCl treatment can significantly increase the leaf osmotic potential (ψs) and relative water content (RWC); reduce the Na + and Clcontents and Na + /K + ratio; and simultaneously enhance the leaf antioxidant enzymes (CAT and APX, POD and SOD) activity, together with the mitigated ROS damage (lower H 2 O 2 and MDA contents). Thus, it can apparently restore the salt stress-inhibited growth and photosynthetic capacity of Jackson and Lee68 seedlings, of which the salt-sensitive cv. Jackson displayed more pronounced effects. This may be related to the fact that, except for DHFe as a kind of antioxidant, foliar application of DHFe could enhance the transcription levels of GmCLC1 in roots and leaves and those of GmSOS1 in roots of Jackson plants under salt stress. When continuously cultivated to maturity, foliar spraying DHFe under salt stress could improve, to a certain extent, the seed traits (including the numbers of pods and seeds and seeds dry weight per plant) of both soybean cultivars. This approach may also provide a valuable theoretical basis and technical guidance for future practical application of DHFe as a type of plant growth promoter for the chemical regulation of foliar DHFe spray in mitigating salt injury to soybean and other crops under saline cultivation conditions.
