“…It was determined the relative Chl content. A measurement of Chl was made between the hours of 9:00 and 12:00 am using a SPAD (Soil Plant Analytical Development) chlorophyll meter reading (SCMR) SPAD502-Plus (Konica Minolta, Tokyo, Japan), according to Namwongsa et al (2018). After calibrating, SPAD meter was shut by squeezing it without inserting a leaf, measurements were taken for each control and treated on the second or third fully developed leaf from the top of the main stem.…”

Egypt which has a long-life cycle and a high-water requirement in general. Sugarcane production and growth are negatively impacted by water constraint, especially during the key water requirement period. This study compared nine sugarcane genotypes to the commercial genotype GT.54-9 (Saccharum spp.) in terms of cane yield, sugar yield, and juice quality related to physio-biochemical attributes including chlorophyll (Chl) Soil Plant Analysis Development (SPAD index), Relative Water Content (RWC), and proline content as a biochemical constituent. Under three levels of drought stress (87.5, 75, and 62.5% of reference crop evapotranspiration (ET0), 2 Way Randomized Complete Block Design (RCBD) with two factors and three replications was used in this study. In the severe water scarcity situations (62.5% of ET0). The results showed that the most promising genotypes (G.2004-27 and G.99-103) had good values for the investigated parameters. The work adds to our knowledge of genotype-screening for drought resistance as an effective technique for choosing materials for advanced breeding programs, especially in controlled drought environments. More genomic and molecular research is required to comprehend the precise processes behind sugarcane drought resilience.

“…Maintenance of high-water uptake under drought stress is also facilitated by improved root/shoot ratio in drought-tolerant cultivars [18]. Namwongsa et al [19] observed that roots of sugarcane genotypes showed reduced growth in the upper soil layers (0 to 30 cm) in response to drought stress, whereas growth in the lower soil layers (below 30 cm) increased substantially. Under water-limited conditions, assimilated partitioning towards the roots area relatively higher than to shoots [20].…”

Among various abiotic stresses, water is reported as a rare entity in many parts of the world. Decreased frequency of precipitation and global temperature rise will further aggravate the situation in future. Being C4 plant, sugarcane requires generous water for the proper growth. Plant root system primarily supports above-ground growth by anchoring in the soil and facilitates water and nutrients uptake from the soil. The plasticity and dynamic nature of roots endow plants for the uptake of vital nutrients from the soil even under soil moisture conditions. In sugarcane, the major part of root system are generally observed in the upper soil layers, while limited water availability shifts the root growth towards the lower soil layer to sustained water uptake. In addition, root traits are directly related to physiological traits of the shoot to cope up with water limited situations via reduction in stomatal conductance and an upsurge in density and deep root traits, adaptations at biochemical and molecular level which includes osmotic adjustment and ROS detoxification. Under stressed conditions, these complex interactive systems adjust homeo-statically to minimize the adverse impacts of stress and sustain balanced metabolism. Therefore, the present chapter deals with physiological and biochemical traits along with root traits that helps for better productivity of sugarcane under water-limited conditions.
