“…Increase in proline levels ~20%, as compared to control during the entire period of applied stress suggested effective osmotic adjustment contributing to osmotic stress tolerance in niger. The observed proline levels in niger were in consonance with those of drought stressed sugar cane (Abbas et al, 2014) and corn cultivars (Sinay and Karuwal, 2014) (Table 1).…”

Drought stress is a highly pervasive and economically damaging abiotic stress that affects plant yield and productivity worldwide. Physiologically, drought stress in plants is associated with oxidative stress leading to tissue damage. Drought stress imposed over 72 h in 10 days old seedlings of Guizotia abyssinica Cass, niger (cv; RCR-18) under greenhouse conditions resulted in elevated levels of oxidative stress markers such as H 2 O 2 , malondialdehyde, proline, reduced glutathione and ascorbate in a time-dependent manner. Levels of antioxidant enzymes: peroxidases and glutathione reductase, and metabolic enzyme: amylase and acid phosphatase were moderately enhanced. The levels of stress markers, antioxidants, and recovery upon re-watering suggested that the antioxidant system in niger could withstand the drought stress for up to 48 h under greenhouse conditions.

“…Several studies have already conducted to compare sugarcane cultivars under well-watered and water deficit conditions in pots (Machado et al, 2009;Carlin and Santos, 2009;Pincelli and Silva, 2012;Abbas et al, 2014) and the field (Gava et al,. 2011;Boaretto et al, 2014) in order to identify drought-tolerant cultivars to be planted in soils that are prone to water deficit.…”

Few studies have focused on water deficit for sugarcane, whose damage could be reduced with Si, as shown in other crops. This study aimed to determine whether Si fertilization enhances the best recovery of sugarcane after two periods of the formative phase (tillering and early grand growth) for RB86-7515 (drought tolerant) and RB85-5536 (drought sensitive), and which growth phase is beneficial for each cultivar. It was investigated: 1) the effect of Si fertilization on total Si uptake, and on soluble Si in soil; 2) whether Si uptake could provided increased stalk yield, juice quality, dry biomass compared to well-watered treatments. Two experiments were conducted in pots under greenhouse: one with RB86-7515 and another with RB85-5536. Treatments were: 1-Non-Deficit+Si, 2-Non-Deficit-Si, 3-Early Deficit (ED)+Si, 4-ED-Si, 5-Late Deficit (LD)+Si, and 6-LD-Si. Silicon fertilization provided best recovery of sugarcane (superior sugar, stalk yield, and dry biomass) after early and late water deficit compared to its absence for both cultivars. For RB85-5536, Si fertilization propitiated similar recovery for water deficit and continuous irrigation treatments. No differences were observed between periods of water deficit. Therefore, Si fertilization at planting should be considered another tool for reducing the damage caused by water deficit in sugarcane.

“…Levels of chlorophyll a, b, total and also leaf greenness declined after a period of drought stress. Allegedly, an amino acid that was synthesized by the tissue, with the help of NRA, more focused to synthesize secondary metabolites such as phenols, proline and antioxidant because the compounds were needed to protect the cells from damage during drought stress period (Chakraborty and Pradhan, 2012;Abbas et al, 2014;Beig et al, 2014). The decrease in chlorophyll content during drought stress period was caused by high sunlight energy capture and low water content so that the chloroplast became vulnerable to damage (Biglary et al, 2011;Dastan et al, 2011;Rahimi et al, 2012;Bharwana et al, 2013).…”

A B S T R A C TThe objectives of the study were to determine (1) The level of physiological resistance of oil palm seedlings to drought stress by boron (B) and silicon (Si) application and (2) The mechanism of B and Si actions to induce physiological resistance of oil palm seedlings to drought stress. The B and Si were the elements capably inducing the internal resistance of plant tissues to drought stress, especially through physiological resistance mechanisms. Field trial was arranged in the factorial Randomized Complete Block Design (RCBD) using three blocks as replications. The first factor was six dose of B: 0.00, 0.17, 0.44, 0.87 and 1.31 g plantG 1 . The second factor was five dose of Si: 0.00, 1.15, 2.31, 3.46 and 4.69 g plantG 1 . Observations were done on the Nitrate Reductase Activity (NRA), the content of chlorophyll a, b and total, density, length and width of stomatal aperture, stomatal conductance and transpiration rate, photosynthetic rate and photosynthetic activity per plant, dry weight of plant parts and trunk height and diameter of the oil palm seedlings. The data were analyzed using ANOVA and the means were separated using Duncan's multiple range test at 5% level. Meanwhile, the optimum dose of B and Si were determined using regression analysis. The results showed that B and Si application could induce physiological resistance of oil palm seedlings to drought stress. Mechanism of action of B in inducing physiological resistance of oil palm seedlings to drought stress were by increasing of greenish leaves, width of stomatal aperture and photosynthetic activity per plant while Si application capable to increase of greenish leaves and to decrease the density of lower leaf surface stomatal. The optimal dose of B was 0.33-0.57 g/seedlings and the optimal dose of Si was 2.22 g/seedling in inducing physiological resistance of oil palm seedlings to drought stress.
