“…For Florida plants, PPFM resulted in the highest interaction values of foliage dry matter in the first season followed by PPFM mixed with 10 % methanol for Festival plants. These results are consistent with those obtained by [29,30,31) in strawberry and lavender plants, respectively.…”

“…In addition, Festival plant treated with PPFM in both seasons resulted in the highest interaction of anthocyanin content followed by PPFM combined with 10 %methanol compared with control. This finding was in accordance with Rahman et al [40] and Valizadeh-Kamran et al [31]. Also, the highest interaction values of ascorbic acid content for Festival c.v. was obtained by PPFM that is may be attributed to its ability to produce stimulators such as auxin, cytokinin, and vitamin B12, which could increase the biosynthesis pathway of ascorbic acid production [28].…”

Pink pigmented facultative methylotrophic bacterium (PPFM) has a favorable impact on plant development and production, it is known as a biostimulator, biofertilizer and biocontroller. Here we investigate the effect of foliar spraying of PPFM, 10% methanol,30% methanol, and their combinations on the growth, fruit quality, and yield of two strawberry cultivars. PPFM was isolated from cotton leaves using imprinting technique. 16S rRNA sequence analysis identified it to be Methylobacterium radiotolerance. Its 16S rRNA sequence were deposited in the Gene Bank under accession number MT644122.1. Two field experiments were conducted during the 2017/2018 and 2018/2019 seasons to investigate the effect of foliar spraying of PPFM and methanol (10 and 30%) on the growth, fruit quality, and yield of two strawberry cultivars. The obtained results showed that, there were no significant differences in the most characteristics between the two cultivars except foliage fresh weight and early yield were higher in cv. Florid, however, Festival cv. recorded higher total yield /plant, anthocyanins and ascorbic acid content in both seasons. Spraying PPFM exhibited the highest values of chlorophyll, fresh weight, total yield and quality. Furthermore, PPFM combined with methanol 10% gave the highest values of leaf area, dry matter %, early yield and some fruit quality. Spraying cv. Florida with PPFM resulted in the best interactions for early yield. However, the best interaction for total yield and most fruit quality features was observed with Festival c.v. and spraying PPFM. It is reasonable to conclude that PPFM is the most effective treatment, increasing strawberry total yield/fed by 28.1 % in the 1st season and 27.91 % in the 2 nd season compared to the control.

“…The same mechanism has been described for other species [64][65][66], and most likely contributes to the (relative) salt tolerance of the lavender varieties. Supporting this notion, recent publications can be cited highlighting the importance of K + homeostasis and the maintenance of a relatively high K + /Na + ratio in leaves of L. stoechas [67], or the fact that foliar K + application ameliorates the responses to salt stress in L. angustifolia [51].…”

Global warming is not only affecting arid and semi-arid regions but also becoming a threat to agriculture in Central and Eastern European countries. The present study analyzes the responses to drought and salinity of two varieties of Lavandula angustifolia cultivated in Romania. Lavender seedlings were subjected to one month of salt stress (100, 200, and 300 mM NaCl) and water deficit (complete withholding of irrigation) treatments. To assess the effects of stress on the plants, several growth parameters and biochemical stress markers (photosynthetic pigments, mono and divalent ions, and different osmolytes) were determined in control and stressed plants after the treatments. Both stress conditions significantly inhibited the growth of the two varieties, but all plants survived the treatments, indicating a relative stress tolerance of the two varieties. The most relevant mechanisms of salt tolerance are based on the maintenance of foliar K+ levels and the accumulation of Ca2+ and proline as a functional osmolyte in parallel with increasing external salinities. Under water stress, significant increases of Na+ and K+ concentrations were detected in roots, indicating a possible role of these cations in osmotic adjustment, limiting root dehydration. No significant differences were found when comparing the stress tolerance and stress responses of the two selected lavender varieties.

“…Foliar application is beneficial in reducing chemical fertilizer inputs and even is more influential in meeting the emergent nutrients need of plants and sometimes meet the long-term micronutrients needs and hence improves the plant growth, development, and productivity 5 , 8 , 9 . Potassium is a significant nutrient element with un-substitutable roles in several vital physiological processes, such as stomatal movement, osmotic regulation, enzymatic activity, water balance maintenance, carbohydrate translocation, membrane polarity & stability, and pH equilibrium, as well as plays chief roles in the assimilates translocation 10 – 13 and in secondary metabolism of plants 14 . Potassium has a pivotal role in the growth, development, and enhancement of tolerance and survival rate under stressful conditions.…”

Salinity is one of the predominant abiotic stress factors that influence the growth and productivity of plants. Salinity adversely impacts the growth responses via ionic toxicity, osmotic stress, impaired nutrients uptake, hormonal disparity, and the over-production of reactive oxygen species. To study the effects of salinity stress (0, 50, 100, and 150 mM) and foliar treatments (dH2O, 2 g L−1 Dobogen biostimulant, 2 g L−1 KNO3, and 2 g L−1d-glucose) on the growth and physiological responses of Tanacetum balsamita, a factorial experiment was conducted based on the completely randomized design at the research greenhouse of Azarbaijan Shahid Madani University, Iran. The results showed the significant interaction effects of salinity and foliar sprays on chlorophyll a, K+, Na+, Mg2+, Fe2+, Zn2+, Mn2+, and Si content, K/Na ratio, and total phenolics and flavonoids content. The highest phenolic content was acquired with 100 mM salinity and foliar spray of Dobogen and glucose, 50 mM NaCl × KNO3 application, and 50 mM salinity × no-foliar application. The highest K/Na ratio was observed in control plants and controls × KNO3 and/or Dobogen application. The greatest Si content was recorded with no-salinity × Dobogen and KNO3 applications and no-saline × no-foliar (control) plants. The independent effects of treatments influenced malondialdehyde, flavonoids, proline contents, and catalase activity. Chlorophyll b and superoxide dismutase were affected by the salinity. Total soluble solids and Ca2+ content were responsive to the foliar applications. Malondialdehyde and proline content was the highest at 150 mM salinity. Salinity adversely affected the physiological responses of costmary. However, foliar treatments partially ameliorated the salinity effect, and the results with more detailed studies would be advisable to the extension section and pioneer farmers.
