“…These results’ data verify and approve the anterior other investigations [4,10,50,54,55,56,57,58,59,60] that indicate that the nitrogen availability at plants and flowers affected the process respiration of ethylene with secondary effects on the prosperity and development of plants.…”

“…Our evaluations are established on the ethylene released from the respiration of flowers in two conditions: abiotic (nitrogen flow) and biotic (synthetic air flow) using laser-based photoacoustic spectroscopy and are in good agreement with those revealed in the specialized literature [48,49,50,51,52,53,54,55,56,57,58,59,60].…”

“…Laser spectroscopy is very precise; a molecular transition can be measured with very high efficiency and each molecular gas has many specific lines For this argumentation, the infrared wavelength domain ranges from 9.2 to the 10.8 μm and the selection of a spectral fingerprint is based on an overall consideration of detection sensitivity, potential spectral interference and availability of laser sources; the molecule gives a unique, specific absorption pattern that can be clearly separated from other gases. Otherwise, if there is a complex mixture of gases, care has to be taken to choose a proper absorption line for the determination of the concentration, where there should be low or no interference with the absorption lines of other gases [45,54,55,56,57].…”

Ethylene is a classical plant hormone and has appeared as a strong molecule managing many physiological and morphological reactions during the life of a plant. With laser-based photoacoustic spectroscopy, ethylene can be identified with high sensitivity, at a high rate and with very good selectivity. This research presents the dynamics of trace gases molecules for ethylene released by cherry flowers, apple flowers and strawberry flowers. The responses of distinctive organs to ethylene may fluctuate, depending on tissue sensitivity and the phase of plant development. From the determinations of this study, the ethylene molecules at the flowers in the nitrogen flow were established in lower concentrations when the value is correlated to the ethylene molecules at the flowers in synthetic air flow.

“…There is an optimal relationship between the nitrogen content in the plant and CO 2 assimilation, where decreases in CO 2 fixation are well documented for N-deficient plants. Nitrogen deficiency is associated with elevated levels of ethylene (which increase boll shedding), suggesting ethylene production in response to N-deficiency stress [77]. N is also an essential nutrient in creating plant dry matter, as well as many energy-rich compounds which regulate photosynthesis and plant production [78], thus influencing boll development, increasing the number of bolls plant −1 and boll weight.…”

Seed quality is one of the most important factors for stand establishment in cotton (Gossypium Sp.), and the use of good-quality seeds is therefore essential to obtain an optimum plant population. Conditions prevailing during seed formation can affect the quality of seed produced, and hence crop establishment in the next growing season. These conditions can affect the germination of the seeds and the ability of the seedlings to emerge from soil. Field experiments were conducted to investigate the effect of nitrogen (N), phosphorus (P), potassium (K), foliar application of zinc (Zn) and calcium (Ca), and the use of plant growth retardants (PGR) [e.g., 1, 1-dimethyl piperidinium chloride (MC); 2-chloroethyl trimethyl ammonium chloride (CC); or succinic acid 2, 2-dimethyl hydrazide (SADH)], during square initiation and boll setting stage, on growth, seed yield, seed viability, and seedling vigor of Egyptian cotton (G. barbadense). Dry matter yield, total chlorophyll concentration, K, Zn and P-uptake plant −1 , were increased with the addition of K, foliar application of Zn, and different concentrations of P (576-1728 g•ha −1 of P). Seed yield plant −1 and plot −1 , seed weight, seed viability, seedling vigor, and cool germination test performance increased as a result of the addition of the high N-rate (142.8 kg•ha −1 N), the high P-rate (74 kg•ha −1 P 2 O 5), K (47 kg•ha −1 K), and from application of Zn, and Ca and the PGR. From the findings of the present study, band application of such treatments showed improved cotton-seed yield and affected the quality of seed produced, and hence crop establishment in the next growing season.

The b-cyanoalanine pathway in plants detoxifies cyanide by assimilating this metabolic poison. Given the possibility that cyanide in soil could serve as an alternate source of nitrogen for plant nutrition, this study investigated whether nitrogen deprivation of wheat seedlings altered the activity of the first enzyme of the pathway (b-cyanoalanine synthase) or asparaginase. The results suggest that ambient, nontoxic concentrations of soil cyanide may serve as an alternate source of nitrogen for plants under nitrogen-limiting conditions.
