“…Boaretto et al (2014) found that improved performance of tolerant cultivar IACSP 94-2094 under 2 levels of soil water restriction (70 and 30% Soil Available Water Content) was associated with a more efficient antioxidant system response, particularly under conditions of mild stress, compared the susceptible cultivar IACSP 95-5000. Kido et al (2012) subjected 20 commercial sugarcane cultivars to water stress for 3, 10, and 20 days and observed increased expression in the glutathione peroxidase-encoding gene in tolerant cultivars.…”

ABSTRACT. Drought is one of the most frequent abiotic stresses limiting the productivity and geographical distribution of sugarcane culture. The use of drought-tolerant genotypes is one approach for overcoming the effects of water stress. We conducted a comparative study to identify gene expression profiles under water stress in tolerant sugarcane roots. Two different cultivars, 1 drought tolerant (RB867515) and 1 drought susceptible (SP86-155), were evaluated at 4 sampling time points (1, 3, 5, and 10 days) using the cDNA-amplified fragment length polymorphism technique. A total of 173 fragments were found to be differentially expressed in response to water stress in the tolerant cultivar. Seventy of these were cloned, sequenced, and categorized. Similarity analysis using Candidate genes to drought tolerance in sugarcane BLAST revealed that 64% of the fragments differentially expressed code proteins classified as no hits (23%), hypothetical (21%), or involved in stress response (20%), with others were involved in communication pathways and signal transduction, bioenergetics, secondary metabolism, and growth and development. Four genes were analyzed and validated using real-time quantitative polymerase chain reaction to determine their expression and showed consistency with the cDNA-amplified fragment length polymorphism analyses. Our results contribute insight into the molecular responses to water stress in sugarcane and possibility to the development of cultivars with improved tolerance to drought.

“…The economy in water and nutrients for plant cultivation will depend on the efficiency of the sensorbased controllers for irrigation to avoid either drainage or drought, which causes waste of water or growth limitation, respectively (Cia et al, 2012;Boaretto et al, 2014;Medici et al, 2014). The lack of such controllers at a low cost and ready to be used in commercial conditions may explain why precise irrigation is rarely used for growing plants in pots, as most use timers or manual control (Montesano et al, 2016).…”

“…This crop is cultivated in several types of soils, including sandy and sandy loam soils sandy soils with low water-storage capacity that are subjected to drought (Boaretto et al, 2014). Negative impacts of water deficit have already been reported on the sugar and stalk yield (Ramesh, 2000;Silva et al, 2008;Oliveira et al, 2011;Boaretto et al, 2014).…”

“…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. Despite some drought-tolerant cultivars having been identified, some sensitive cultivars are still being used under field conditions due to a superior sugar yield, even with a low stalk yield, which cannot be found in several drought-tolerant cultivars.…”

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.
