“…Proline and total soluble sugars are organic osmolytes and assist in cell osmoregulation and mitigation of stresses for plants [ 77 , 78 , 79 , 80 ]. A close relationship between the concentration of osmoprotectants and tolerance of stress has been noted, and they are considered one of the indicators for the possibility of stress tolerance [ 81 ].…”

Selenium (Se) and silicon (Si) are considered advantageous elements to induce plants’ tolerance to various environmental stresses. Wheat yield is negatively affected by salinity stress, especially in dry and semi-dry areas. Therefore, the objective of the current study was to investigate the effects of Se, Si and their combinations (0 as control, Se15, Se30, Si15, Si30, Se15 + Si15, and Se30 + Si30 mM) in alleviating the deleterious effects of salinity stress (7.61 dS m−1, real field conditions) on anatomical characteristics as well as the physio-biochemical and productivity parameters of wheat plants. The selenium and silicon treatments and their combinations caused significant amelioration in growth, anatomical and physiological attributes, and grain yields of salinity-stressed wheat in comparison with the untreated plants (control treatment). The integrated application of Se30 + Si30 significantly increased plant growth (i.e., plant height 28.24%, number of tillers m−2 76.81%, fresh weight plant−1 80.66%, and dry weight plant−1 79.65%), Fv/Fm (44.78%), performance index (PI; 60.45%), membrane stability index (MSI; 36.39%), relative water content (RWC; 29.39%), total soluble sugars (TSS; 53.38%), proline (33.74%), enzymatic antioxidants (i.e., CAT activity by 14.45%, GR activity by 67.5%, SOD activity by 35.37% and APX activity by 39.25%) and non-enzymatic antioxidants (i.e., GSH content by 117.5%, AsA content by 52.32%), yield and its components (i.e., number of spikelets spike−1 29.55%, 1000-grain weight 48.73% and grain yield ha−1 26.44%). The anatomical traits of stem and leaves were improved in wheat plants treated with Se30 + Si30. These changes resulting from the exogenous applications of Se, Si or their combinations, in turn, make these elements prospective in helping wheat plants to acclimate successfully to saline soil.

Genotypes used in present investigation consisted of five cotton varieties belong to (Gossypium barbadense, L.). Three of these varieties were long staple, BBB (big black boll) (P1), Australian (P2) and G97 (P3) while the other two varieties were extra-long staple, Giza 92 (P4) and G96 (P6). Hybrids produced from these parents and evaluated with their parents in Sakha Agricultural Research Station, Egypt. Studied traits were; first fruiting node, days to first flower appearance, duration of the boll maturation, upper half mean (U.H.M), fiber strength and micronaire value. Highly significant differences among parents were detected for all traits, excluding days to opening first boll and upper half mean . Difference between single crosses was highly significant for all traits, except for days to first flower and upper half mean . Significant differences between double crosses were detected for all traits, excluding upper half mean . Alpha lattice analysis exhibited more efficiency than randomized complete block design at analyzing all of studied traits except for first fruiting node. Lowest values of (CV%) and SE were recorded for all traits excluding micronaire reading in Reml analysis which indicates high experimental precision

We aimed to investigate the effects of some seed priming and foliar applications on stress prevention in cotton under deficit irrigation conditions. Seed priming with mepiquat chloride (PIX) and foliar applications of salicylic acid (SA) and proline (PRO) were tested at three levels of irrigation at 25, 50, and 100% of field capacity. Plant height, boll number, fiber length and fiber strength were significantly affected by the interaction of irrigation level × treatment. The effects of irrigation level and treatment were significant for boll weight, seed index, seed cotton yield and lint yield. When deficit irrigation conditions (25%) were compared with full irrigation, plant height decreased by 21.6 %, boll number by 18.1 %, boll weight by 26.0%, seed index by 5.8%, seed cotton yield by 25.6% and lint yield by 24.6%. Seed priming with PIX and foliar application of PRO produced significantly higher seed cotton and lint yields, whereas SA application had favourable fiber quality parameters under deficit irrigation conditions. PRO slightly increased fiber fineness. Foliar application of SA positively affected chlorophyll content (SPAD) and leaf area index (LAI) under deficit irrigation. In conclusion, it was recommended that all three practices could be successfully used to alleviate negative impacts under deficit irrigation conditions.
