“…Treatment W2 recorded an average of (6.67) and it differed significantly from treatment W4 with an increase of (103.3)% respectively. These results are consistent with what was found (Sozharajan and Natarajan, 2016). As for the bilateral interaction, where treatment W1S1 recorded the highest average of (14.60) and the lowest average of treatment W4S0 reached (2.09).…”

“…The results of the statistical analysis in table (1) showed that there were significant differences when adding different levels of silicon, where treatment S1 recorded the lowest average sodium concentration and amounted to (0.50)%, respectively, with a decrease of (46%) compared with the comparison treatment S0, which recorded an average of (0.73)%, and the reason was attributed That silicon reduces sodium absorption, these results are consistent with (Farooq et al, 2019). As for the levels of irrigation water, where the highest average concentration of sodium in treatment W4 was (0.96%) than the rest of the treatments W1, W2 and W3, an increase of (231.0, 92 and 37.1)%, respectively, as well as the W3 treatment, which recorded an average of (0.70)% compared to treatments W1 and W2 with an increase of (141.1 and 40%) that the increase of sodium with the increase in the salinity of the irrigation water because of the increase in the concentration of sodium and this was confirmed by (Sozharajan andNatarajan, 2016 andAl-Shammari, 2021). As for the interaction between silicon and irrigation water, where treatment W4S0 recorded the highest average sodium concentration amounted to (1.36%) and treatment W1S1 recorded the lowest average sodium concentration amounted to (0.24)%.…”

A factorial field experiment was carried out in one of the agricultural fields of Dar Al Salam sub-district in Diyala governorate during the autumn season of 2020, to reduce the role of calcium silicate in reducing the effect of salt stress on the growth and yield of maize. The experiment included two factors, the first factor: four levels of salinity for irrigation water W1, W2, W3 and W4 (1.3, 2, 4, 6) dsm-1 and Factor II: Three levels of calcium silicate S0, S1, and S2 (0, 75, 150) kg h-1. The transactions were distributed according to a randomized complete block design (R.C.B.D) using a split-plot design system, with three replications. The seeds of yellow corn variety (Corn) of Spanish origin were planted on 29/7/2020 after preparing the experimental ground. Fertilizers were added following the fertilizer recommendation. The most important results obtained showed that Silicon addition treatment of 75 kg h-1 S1 gave the highest significant increase in dry weight, which amounted to 420.5 gm plant-1, compared with treatment S0 and S2, with an increase of 19.8 and 15.7%, respectively.

“…When toxic ions are continually sequestered into vacuoles, organic solutes that are compatible with the cells metabolic activities must be accumulated within the cytosol and organelles to balance osmotic pressure (Munns et al, 2016;Yang & Guo, 2018). Compatible solutes or osmo-protectants are of low molecular mass and well soluble compounds that are typically non-toxic at high cellular concentrations (Sozharajan & Natarajan, 2016). Compatible osmolytes may also reduce water loss and enhance cell turgor and cell expansion.…”

“…Compatible osmolytes may also reduce water loss and enhance cell turgor and cell expansion. Common osmolytes include proline, sucrose, polyols, mannitol, glucose, fructose and sucrose (Yang & Guo, 2018) (Sozharajan and Natarajan, 2016). Proline accumulation induced by NaCl has been shown to correlate with salinity induced growth inhibition.…”

“…Proline accumulation induced by NaCl has been shown to correlate with salinity induced growth inhibition. Further, in response to abiotic stress glycine betaine has been shown to serve as an effective compatible osmolyte and scavenger of Reactive Oxygen Species (ROS) (Sozharajan and Natarajan, 2016). The accumulation of these compatible solutes also occurs in response to drought stress and low temperature.…”

Evaluating the functional role of betacyanin in salinity tolerance of Horokaka (Disphyma australe)

<p>Yield loss in agriculture due saline soils is a growing problem in arid and semi-arid regions as traditional crop species are inherently sensitive to salinity in the root zone. In the face of diminishing fresh water resources it is necessary to explore the traits which allow naturally salt tolerant species to exploit high saline environments. In the hope of transferring these traits via genetic modification to traditional crop species, or utilising these species as niche crops in their own right. While a majority of plants appear green, red pigmented plants are commonly associated with marginal environments. In these leaves anthocyanins or less commonly betalains are responsible for leaf reddening. The betalains are small class of tyrosine derived chromo alkaloids found in the core Caryophyllales and in some Basidiomycetes. There are two structural groups: the red/violet betacyanins and the yellow/orange betaxanthins. Due to this distribution pattern, betalain pigments are thought to function in salinity stress tolerance. However, minimal research has been conducted to support this salinity tolerance hypothesis due to a lack of an appropriate model species. Horokaka (Disphyma australe) exhibits colour dimorphism among populations, green and red morphs grow contiguously in coastal environments where the frequency of red morphs positively correlates with increased substrate salinity. Betacyanins have previously been implicated in serving a photo protective for D. australe. In dimorphic populations D. australe along the south Wellington coastline, the red morph has been shown to be more tolerant to the combination of high light and salinity, as measured by higher CO2 assimilation rates, reduced inhibition of PSII and enhanced water use efficiency relative to the green morph. In these studies, betacyanin production in the red morphs was shown to depend on duel exposure to both salinity and high light, however the green morph was unable to produce betacyanin under the same conditions (Jain & Gould, 2015). This easy manipulation of leaf colour by salinity and high light offers a system to study whether betacyanin pigments aid salinity tolerance. I aimed further investigate the photo protective hypothesis of betalain using D. australe, and how this may influence distribution patterns by focusing on three areas: the capacity for new root growth along a salinity gradient, germination capacity under saline conditions, and ion content in the roots at low, moderate and high NaCl concentrations. Shoots with no roots and a minimum of two mature leaf pairs were cut from green and red morphs of D.asutrale growing in the greenhouse facilities at Victoria University of Wellington. The shoots were grown hydroponically in 10% Hoaglands solution supplemented or not with (50, 100, or 150 mM) NaCl. To test the light screening capacity of leaf betacyanin a red filter was secured of half the green shoots, the cuttings were grown for 5 weeks under a controlled 16h light/ 8h dark photoperiod. Final weights of the shoot and roots, along with tissue water content of the shoots and roots were obtained to establish the relative capacity for new root growth when subjected to increasing salinity. Seeds were germinated in vitro in the presence of increasing NaCl concentrations (0, 100, 200, 300, and 400 mM NaCl), and subject to recovery tests after stress. The germination percentages and velocity were determined to establish te relative tolerance and competitiveness of the two D. australe morphs. Salt treatments were also applied to plants with an established root system, by 14-day treatment with increasing NaCl concentrations (0, 200, 400, 800 mM). The tissue water content of the shoots and ion contents (Na+ and K+) in the roots were determined in the control and the stressed plants of the two colour morphs. The different germination behaviour of the two morphs and capacity for root development appears to contribute to their distribution along a salinity gradient. Despite some differences under the control treatment, the concentrations of the two ions (Na+ and K+) were similar in the two morphs, not explaining differences in salinity tolerance, except for the increase of K+ in the roots of the green morph in the absence of NaCl. This specific response may be relevant for distribution patterns in D. australe. The ecological implications of these findings, which can contribute to vegetation distribution of D. australe in coastal environments, and the relevance of betacyanin accumulation in salinity tolerance for halophytes, and potential application for improved crop vigour are discussed.</p>
