| Abstract |
Variation of physiological and morphological response is often caused by different soil environments and conditions. Therefore, better understanding of physiological responses and root attributes of sugarcanes subjected under uniform, controllable condition is encouraged. Thus, this study aimed to investigate the responses of rooting and physiological traits of sugarcanes under mimic drought stress as low water potential via PEG induction at early growth stage in hydroponics. Experiment was laid out in split-plot in randomized complete block design (RCBD) with four replications under hydroponic system. The effect of two PEG levels (0.0% and 1.0%) was placed as main plot, whereas the effect of four sugarcane genotypes as sub-plot. Data was recorded on physiological, morphological, and rooting traits as time series during the periods of transplanting to 3 months after planting (MAP). In general, four sugarcane genotypes grown under control conditions showed higher dry weight, height, leaf area, leaf number, root length, root surface area, root volume, SPAD chlorophyll meter reading (SCMR) and Chlorophyll fluorescence (fv/fm) than those grown under PEG treatment. KK3 cultivar contributed to the root proportion into deeper layer (20-40 cm) when subjected to PEG treatment. Photosynthesis was decreased due to reduced stomatal conductance, as a mechanism to decrease CO2 exchange rate. The response of photosynthesis, transpiration rate, and leaf area correlate to the performance of sugarcane biomass in response to low water potential via PEG induction under hydroponics. This information provides a basic knowledge for further against drought stress work. |
