“…This may be the factor responsible for firmness increasing in the fruit. The Si fertilization in tomato plants reduces the occurrence of cracked fruits, which are classified as noncommercial (Marodin et al, 2014). Fruit firmness is an essential characteristic of post harvest conservation during transportation and commercialization, and it is related to shelf life.…”

This study aimed to investigate the effect of silicon (Si) sources and doses on the physicochemical quality as well as post-harvest conservation of tomato fruits. Treatments were arranged in a 3 x 5 factorial scheme corresponding to sources [calcium silicate, potassium silicate and sodium silicate] and five doses of Si (equivalent to 0, 100, 200, 400 and 800 kg/ha SiO 2 ). Randomized blocks were the experimental design, with four replications. Soluble solids, vitamin C, lycopene, titratable acidity, mature fruit firmness, initial firmness, firmness half-life, time until reaching firmness equivalent to 3.0 x 10 4 N/m 2 and 2.0 x 10 4 N/m 2 and Si content in fruits were evaluated. Soluble solids, vitamin C and lycopene of fruits increased with increasing doses of Si, except for the highest dose. Calcium and sodium silicate provided the highest lycopene concentration in fruits. An increase in initial firmness, number of days until reaching firmness half-life and firmness equivalent to 3.0 and 2.0 x 10 4 N/m 2 were observed along with increasing doses of Si. Tomato fertilization with calcium silicate, potassium silicate and sodium silicate, used as sources of Si, increased the post-harvest conservation as well as the physicochemical quality of tomato.

“…In addition, silicon fertilization promotes an increase in fruit yield in the tomato crop (Marodin et al, 2014). Despite the proven effects of Si on the mentioned metabolic processes, little information on its effects on traits related to post-harvest quality can be found.…”

“…Applied Si was readily taken up and accrued in plant tissues (like root, shoot, leaves and grains), increased P nutrition and nitrogen use efficiency with increase in Si supply (Neu et al, 2017). Marodin et al, (2014) suggested that the application of Si using potassium or calcium silicates increased the levels of Si in tomato leaves with increase in crop yield at the highest Si rate (800 kg ha -1 ). Calcium silicate application to saline soil at 100 or 75 mg kg -1 might be a useful strategy for reducing the impact of salinity on rice while improving plant growth, yield, P, Si and K nutrition by reducing the accumulation or uptake of Na in plant parts.…”

Silicon (Si) is a beneficial nutrient for plant growth and productivity. Our investigation was conducted to study the influence of Si application for ameliorating the adverse effects of salinity on rice through sodium regulation in plant tissues. Three same textured soils (sandy clay loam) with different electrical conductivity (EC e : 2.85, 5.28 and 7.57 dS m-1) and pH (8.1, 8.6 and 8.9) were collected at 0-15 cm depth from the Bahauddin Zakariya University Agricultural Farm in Multan, Pakistan. The Si @ 50, 75 and 100 mg kg-1 as calcium silicate was applied to pots containing 10 kg sandy clay loam soil (sand 48%, silt 17%, clay 35%). A control without Si application was also maintained. The completely randomized design in 3 × 4 factorial experiment with three replications was established. Thirty days old, seedlings of Kernel Basmati rice were transplanted manually and standard cultural practices were followed. Results showed a significant (p<0.05) effect of soil salinity on rice growth and yield parameters. A reduction in grain, straw, leaf and root concentrations of Si, P and K/Na was observed under salinity; however, Si application at 100 mg kg-1 ameliorated the salinity stress and significantly increased the root/shoot dry weights, tiller numbers, grain numbers per spike, paddy yield, harvest index, and P and Si concentrations in root, straw, leaves and grains over control though similar to Si @ 75 mg kg-1 for shoot dry weight, number of tillers, harvest index, grain/root P concentration and leaf Si concentration. The Si application affected K/Na by increasing K uptake with an associated decrease in Na concentration in plant tissues. Thus, Si application at 100 or 75 mg kg-1 soil (200 or 150 kg ha-1) could be a useful strategy for rice production in salt-affected lands. Shoot dry weight, Number of tillers. Harvest index, Grain/root P conc., Leaf Si conc.

“…The Si treatment increased the yield and reduced the cracked/damaged tomato fruits (Marodin et al, 2014). Five applications of potassium silicate over 12 days significantly reduced the severity of the tomatoes' powdery mildew (Yanar, Yanar, & Gebologlu, 2011) and increased the plants' resistance to disease, which is associated with active and/or passive mechanisms (Ouellette et al, 2017).…”

Gaseous, Physicochemical and Microbial Performances of Silicon Foliar Spraying Techniques on Cherry Tomatoes

Silicon (Si) foliar spraying techniques (17 mM Si leaf and whole plant) were applied to determine the effect of gaseous, physicochemical and microbial activities on cherry tomatoes. Whole treated tomato plant showed significantly (p ≤ 0.05) the lowest respiration and ethylene production occurred during harvest time and after storage. The lowest fresh weight loss, fungal incidence and microbial activity were observed in whole plant treated tomatoes. In addition, the longest shelf life 24 days and the highest firmness were maintained by whole plant Si treated tomatoes. A higher vitamin C content was found in the whole Si treated tomato plants compared to Si leaf or no treated tomatoes. In addition, in the whole Si treated tomato plant showed the lowest soluble solid content by suppressing the color development. Based on the above results, whole plant Si treatment may be a useful technique to maintain respiration, ethylene production, firmness, shelf life and microbial activity of cherry tomatoes.
