Compared with sole nitrogen (N), the nutrition mixture of ammonium (NH4+) and nitrate
(NO3–) is known to better improve crop yield and quality. However, the mechanism …

The hydroponic experiment was conducted to study the effects of ammonium (NH 4+): nitrate
(NO 3−) ratios on growth, photosynthetic responses, chloroplast ultrastructure and root …

The effects of CO 2 enrichment on water balance and nitrogen (N) assimilation in cucumber
(Cucumis sativus L. cv. Jinyou No. 35) seedlings under salt stress were investigated. Two …

Nitrogen (N) is an essential macronutrient for plants and profoundly affects crop yields and
qualities. Ammonium (NH4+) and nitrate (NO3−) are major inorganic N forms absorbed by …

Nitrogen (N) is taken up by most plant species in the form of nitrate (NO _3^-) or ammonium
(NH _4^+). Plant response to continuous NH _4^+ nutrition is species‐dependent. In this …

Effects of exogenous sodium nitroprusside (SNP), a nitric oxide (NO) donor, on the salt
tolerance of wheat (Triticum aestivum L.) seedlings indicated that NO donor significantly …

Nitrogen is essential for plant growth and crop productivity; however, nitrogen use efficiency
(NUE) decreases with increasing N supply, resulting in a waste of resources. Molecular …

Potassium (K+) has been reported to alleviate ammonium (NH 4+) toxicity in rice through
some underlying mechanisms, but it still not clear. In addition, K+ is an important cation for …

Abstract Ammonium (NH 4+) can enhance the water stress induced drought tolerance of rice
seedlings in comparison to nitrate (NO 3−) nutrition. To investigate the mechanism involved …

Humic acids (HA s) have a major effect on nutrient uptake, metabolism, growth and
development in plants. Here, we evaluated the effect of HA pretreatment applied with a …
