“…The treatment T 5 (Chelated EDTA calcium @ 0.2% + boric acid @ 0.1%) resulted maximum bunch volume (498.42 ml), length of bunch (19.75 cm) and length of rachis (19.37 cm). Similar findings were reported by Ciccarese et al (2013) in Italia grapes and Karimi (2017) in Sultana grapes. The highest values for TSS (19.53°Brix) and total anthocyanin content (32.22 mg 100g -1 ) were documented in the treatment with foliar application of chelated EDTA calcium @ 0.2% + boric acid @ 0.1%.…”

Muscat Hamburg (Panneer) is the most popular cultivar in Tamil Nadu for its pleasant musk flavor. It is consumed as table variety and also used for juice and wine-making purposes. The present investigation was conducted during summer and winter pruning from April 2016 to March 2018, in the grapes vineyard located at Shanmuganathy dam road, Rayappanpatty village in Cumbum valley of Theni district, Tamil Nadu. The experiment was laid out by adopting Randomized Block Design with seven treatments and three replications. The exeprimental results revealed that the treatment with foliar application of chelated EDTA calcium @ 0.2% + boric acid @ 0.1% recorded the maximum number of bunches (41.00 vine-1), fruit yield (14.87 kg vine-1), individual bunch weight (636.87g), bunch volume (498.42 mL) and TSS (19.530brix). The minimum berry cracking (3.46%), titrable acidity (0.52%) and physiological loss in weight (10.18%) were also recorded in the treatment with chelated EDTA calcium @ 0.2% + boric acid @ 0.1% (T5) as compared to other treatments. Further, the same treatment combination noted the lowest berry shattering (2.42%). Whereas the highest berry diameter was recorded in the treatment with a spray of calcium chloride @ 0.3% than all other treatments.

“…Approximately 10% of plant biomass is composed of K, which not only acts as a co-factor for various enzymes involved in photosynthesis and protein stabilization, but it also hinders Cd-translocation and escalates the production of crucial amino acids, carbohydrates, and nitrogenous compounds. Potassium improves plant stress tolerance by regulating the biosynthesis of polyamines ( Karimi, 2017 ). Polyamines regulate physiochemical procedures of plants under normal conditions and also induce modification in the expression level of stress-responsive genes besides detoxifying metals by vacuolar compartmentalization ( Spormann et al, 2021 ).…”

Iron Oxide and Silicon Nanoparticles Modulate Mineral Nutrient Homeostasis and Metabolism in Cadmium-Stressed Phaseolus vulgaris

The application of nanoparticles (NPs) has been proved as an efficient and promising technique for mitigating a wide range of stressors in plants. The present study elucidates the synergistic effect of iron oxide nanoparticles (IONPs) and silicon nanoparticles (SiNPs) in the attenuation of Cd toxicity in Phaseolus vulgaris. Seeds of P. vulgaris were treated with IONPs (10 mg/L) and SiNPs (20 mg/L). Seedlings of uniform size were transplanted to pots for 40 days. The results demonstrated that nanoparticles (NPs) enhanced growth, net photosynthetic rate, and gas exchange attributes in P. vulgaris plants grown in Cd-contaminated soil. Synergistic application of IONPs and SiNPs raised not only K+ content, but also biosynthesis of polyamines (PAs), which alleviated Cd stress in P. vulgaris seedlings. Additionally, NPs decreased malondialdehyde (MDA) content and electrolyte leakage (EL) in P. vulgaris plants exposed to Cd stress. These findings suggest that stress alleviation was mainly attributed to the enhanced accumulation of K+ content, improved antioxidant defense system, and higher spermidine (Spd) and putrescine (Put) levels. It is suggested that various forms of NPs can be applied synergistically to minimize heavy metal stress, thus increasing crop production under stressed conditions.

“…Plants experience some metabolic change during exposing to cold temperature, including rearrangement of cell membrane composition (Steponkus, 1984), increases in compatible solutes (Ghasemi et al, 2012;John et al, 2010;Karimi et al 2017;Valle, 2002;Zhang et al, 2012), expression of cold-related genes and antifreeze proteins synthesis (Salzman et al, 1996;Thomashow, 1999), altered tissues water content (Salzman et al 1996;Valle, 2002) and increasing in dormancy-related hormones concentration (Koussa et al, 1998). Compatible solutes such as soluble sugars and proline serve as cryoprotective compounds (Karimi 2017;Morin et al, 2007), which can induce osmotic adjustment, maintains turgor in dehydrating cells, and allows plants to tolerate dehydrative stresses (Ghasemi et al, 2012;Wang et al, 2003;Zhang et al, 2012). The amount of tissue water content is thought that mediate supercooling degree in woody plants (Salzman et al 1996;Valle, 2002).…”

The objectives of this study were to compare cold hardiness (CH) of 20 field-grown grapevine (Vitis vinifera L.) cultivars at four stages: Nov., Jan., Mar. and Apr., and to investigate the relationship between CH and soluble carbohydrates, proline, phenolic compounds and water content changes during acclimation and deacclimation stages. After exposure to various freeze test temperatures, cane LT50 values were estimated using electrolyte leakage and Tetrazolium stain test. CH of all cultivars studied increased with the overall trend of declining temperatures from Nov. through Jan., after which the canes began to deacclimate from Mar. and gradually lost CH in Apr.; overall LT50 means were -15.06, -23.73, -22.42 and -12.08, respectively. A relatively high variation of CH was shown in Jan., when ranged from -20.76 to -26.43ºC. In this sampling stage, cultivars were classified as hardy (CH = -24.5 to -26.
