“…These results also revealed that there were different responding mechanisms under various RH treatments in two cultivars. Electrolyte leakage has been widely defined as a key indicator to assess cell membrane stability (Wang et al, 2017), which results in protein denaturation, enzyme inactivation, and can also impair carbohydrate and protein synthesis and degradation (Patriyawaty et al, 2018;Shen et al, 2017). The electrolyte leakage in response to 75% RH treatment was not significantly different to CK in two cultivars, which showed that 75% RH had less effects on cellular membranes under heat stress.…”

The effects of different relative air humidity (RH) levels under high temperature and accompanying vapor pressure deficits (VPDs) on the physiology, photosynthesis, and anatomy of Rhododendron need to be better understood to help in reducing damage to leaves caused by high temperature. In this study, two Rhododendron cultivars were exposed at 45%, 55%, 65%, 75%, and 85% RH to a treatment of constant temperature at 38 °C for 14 days, resulting in a VPD of 3.64, 2.98, 2.32, 1.66, and 0.99 kPa, respectively. The results showed the least reduction of the net photosynthetic rate (Pn) under 75% RH treatment in R. ‘Fen Zhenzhu’ (decreased by 79.8%), and under the 85% RH treatment in R. ‘Zhuangyuan Hong’ (decreased by 75.4%). The decline in relative water content (RWC) was less under the 75% and 85% RH treatments, and electrolyte leakage showed a slight decrease under the 75% RH treatment in the two Rhododendron cultivars. The appearance of the two cultivars under greater RH showed less damage, probably because plants can avoid damage by increasing total chlorophyll content, decreasing stomatal area, stomatal density, and opened stomata ratio, enhancing enzymatic activity and osmoregulation substances, and improving leaf structure. The findings show that greater RH can alleviate damage caused by heat stress and improve thermostability.

“…Extremely high temperatures (above 40°C) and direct effects of heat during flowering (Experiment 2) and pod stages (Experiment 3) may have affected biomass accumulation of Jade-AU and Crystal. Patriyawaty et al (2018a) found that high temperatures significantly reduced dry matter production and grain yield of mungbean cultivars Jade-AU and Crystal. High temperatures impact floral abortion rates, decrease pollen viability and reduce biomass accumulation (Patriyawaty et al 2018b;Rachaputi et al 2019).…”

Context Unmanned aerial vehicles (UAV) with red–green–blue (RGB) cameras are increasingly used as a monitoring tool in farming systems. This is the first field study in mungbean (Vigna radiata (L.) Wilzcek) using UAV and image analysis across multiple seasons. Aims This study aims to validate the use of UAV imagery to assess growth parameters (biomass, leaf area, fractional light interception and radiation use efficiency) in mungbean across multiple seasons. Methods Field experiments were conducted in summer 2018/19 and spring–summer 2019/20 for three sowing dates. Growth parameters were collected fortnightly to match UAV flights throughout crop development. Fractional vegetation cover (FVC) and computed vegetation indices: colour index of vegetation extraction (CIVE), green leaf index (GLI), excess green index (ExG), normalised green-red difference index (NGRDI) and visible atmospherically resistant index (VARI) were generated from UAV orthomosaic images. Key results (1) Mungbean biomass can be accurately estimated at the pre-flowering stage using RGB imagery acquired with UAVs; (2) a more accurate relationship between the UAV-based RGB imagery and ground data was observed during pre-flowering compared to post-flowering stages in mungbean; (3) FVC strongly correlated with biomass (R2 = 0.79) during the pre-flowering stage; NGRDI (R2 = 0.86) showed a better ability to directly predict biomass across the three experiments in the pre-flowering stages. Conclusion UAV-based RGB imagery is a promising technology to replace manual light interception measurements and predict biomass, particularly at earlier growth stages of mungbean. Implication These findings can assist researchers in evaluating agronomic strategies and considering the necessary management practices for different seasonal conditions.

In terms average shoot biomass (including root) of mung beans was reduced by 41%, and the grain yield by 50% compared to normal condition (Patriyawaty et al, 2018). Exposure to high temperature stress hastens the development of reproductive parts and reduces the time to fruit ripening in strawberry Kawabata (2016) also found that short but severe high temstrawberry cultivars 'Nyoho' and 'Toyonoka'.…”
