“…Abiad. Nitrogen is one of the most abundant element in plants and major component of proteins (Kaur et al 2017), therefore, its deficiency influence photosynthesis negatively, which was evident from our observation. Compared to other stresses, the nitrogen deprivation did not affect severely the maximum photochemical efficiency, but the capacity of electron acceptors and electron transport beyond PSII is affected, which is reflected also in the decrease of performance index (Živčák et al 2014).…”

The study examined photosynthetic efficiency of two barley landraces (cvs. Arabi Abiad and Arabi Aswad) through a prompt fluorescence technique under influence of 14 different abiotic stress factors. The difference in the behavior of photosynthetic parameters under the same stress factor in-between cv. Arabi Abiad and cv. Arabi Aswad indicated different mechanisms of tolerance and strategies for the conversion of light energy into chemical energy for both the landraces. This study confirmed the suitability of some chlorophyll fluorescence parameters as reliable biomarkers for screening the plants at the level of photosynthetic apparatus.

“…As the potential of plants to absorb amino acids from soil is widely recognized, the importance of organic N to the terrestrial N cycle has raised a number of questions (Kaur et al ; Uscola et al ). In our study, all four desert herb species could take up large amount of N derived from glycine, consistent with some findings in terrestrial ecosystems (Weigelt et al ; Xu et al ; Gao et al ).…”

“…The forms of chemical N in soils are many and varied, ranging from inorganic N such as ammonium (NH 4 + ) and nitrate (NO 3 − ) to organic N (mainly as free amino acids and short peptides) (Paungfoo‐Lonhienne et al ; Sujatha & Bhat ; Wang et al ). To some extent, the preference of plants and microorganisms for different N forms plays a key role in evaluating the ecosystem N dynamics (Kaur et al ; Tegeder & Masclaux‐Daubresse ) and in determining the fates of N input into natural ecosystems (Ashton et al ; Kaur et al ). However, it is not easy to assess plant N preferences, partly because of different physical, chemical and biological characteristics of the N forms in soil, and these therefore result in different N use efficiency of plants (Weigelt et al ).…”

“…So far, however, research on the N preferences of plants in desert ecosystems has rarely been reported. Moreover, little research has focused on the role of desert herbaceous plants in nutrient conservation (Kaur et al ; Tegeder & Masclaux‐Daubresse ), although such plants are essential for soil restoration and production in desert ecosystems (Wang et al ).…”

Symbiotic plants might be able to regulate a limited nitrogen (N) pool, thus avoiding and reducing competition for resources, through the uptake of different chemical N forms. Our aim was to see whether coexisting herbs showed preference for different forms of N in a temperate desert.• We conducted a situ experiment using the 15 N labeling method in the Gurbantunggut Desert of Northwestern China dominated by Erodium oxyrrhynchum, Hyalea pulchella, Nonea caspica and Lactuca undulata during their growing period (April and May).• Four desert herb species preferentially relied on 15 N-NO 3 for their N nutrition. Multifactor analysis of variance (ANOVA) analysis results showed that species, N forms, months, and soil depths strongly affected N uptake rate. The uptake rate by herbs was higher in May than in April, and higher at 0-5 cm than at 5-15 cm soil layers. Erodium oxyrrhynchum, N. caspica and L. undulata showed different preference on N form over months. Erodium oxyrrhynchum and L. undulata changed their uptake preference from more 15 N-Glycine in April to more 15 N-NH4 in May.• Although the N uptake rate of four desert herbs varied across different soil depths and months, all species absorbed more inorganic N compared with organic N. The higher preference for 15 N-NO 3 and 15 N-NH4 over 15 N-Gly possibly reflects adaptation to different N forms in temperate desert.

“…O nitrogênio (N) é um importante nutriente para os vegetais, pois constituem os aminoácidos, proteínas, ácidos nucleicos entre outros constituintes da célula vegetal essenciais para seu crescimento e desenvolvimento (Kaur, Kaur, & Asthir, 2017). Para a cultura do tomateiro, o suprimento adequado de N é necessário para melhor desenvolvimento, aumento da produtividade e qualidade OzoresHampton et al, 2012).…”
