“…APX plays a key role in catalyzing the process of detoxifying hydrogen peroxide in plant cells under stressful environmental conditions (Caverzan et al, 2012). Higher levels of APX production in plants have been attributed to their tolerance to water stress (Kong et al, 2016). However, APX activities in the cultivars used in this study were not significantly higher under water stress conditions compared to non-stress conditions, except for cultivar Nerica U4 and Nerica U7.…”

“…Similarly, the rice seedlings emerged from primed seeds manifested significantly lower MDA contents as well as ROIsaccumulation (Hussain et al, 2016). No significant differences in the shoot POD activity were observed among plants grown with Se supply levels from 0 to 2 µM, except at 1 µM Se (Kong et al, 2016).…”

Water stress is an enormous problem facing food production, especially in arid and semi-arid regions. Production of free radicals during water stress has led to oxidative stress, which eventually causes death of cells in plants. Therefore, it is important to tackle this issue knowing that rice is one of the most important cereal crops largely cultivated and consumed by humans and animals. The studies aimed at the effect of selenite on physiological and biochemical activities of water-stressed upland rice. Three Upland rice cultivars namely Nerica U4, Nerica U7 and Vandana were collected in Africa Rice Centre, Ibadan. The seeds were sterilized and soaked for 10 hours in different concentrations of Selenite (Se) (0 mg/l, 50 mg/l and 100 mg/l). Primed seed were planted into sterilized-sieved top soils. Plants were subjected to 0 (irrigated) and 8 days (non-irrigated) water stress. Selenite 50 mg/l improved plant height, number of leaves, total carotene, chlorophyll contents, biomass, grain number of upland rice during water stress. Selenite increased activities of APX as water stress progressively increased consequently, low MDA content was observed in cultivar Vandana. Furthermore, selenite significantly improved total carotene, chlorophyll contents, anthocyanin, and dry shoot weight in cultivar Nerica U7 during water stress. Selenite significantly stabilized activities of anthocyanin and CAT in cultivar Nerica U4 during water stress. Hence high grain yield was recorded in Nerica U4 and U7 in selenite primed upland rice during water stress. Selenite reduced lipid peroxidation in upland rice at 100mg/l. Therefore, it can be concluded that response of rice to selenite during water stress is based on tolerance capacity of the cultivars and also, selenite 50mg/l can help to improve growth and yield of upland rice in drought-prone area.

“…Other features can be extracted from a combination of single wavelengths. Kong et al [14] used NIR hyperspectral imaging to determine the distribution of malondialdehyde, a stress indicator, in rape leaves. They found that an optimal prediction performance for malondialdehyde detection was achieved by an extreme learning machine model with 23 wavelengths selected by competitive adaptive reweighted sampling (CARS).…”

Background: Assessing the impact of the environment on plant performance requires growing plants under controlled environmental conditions. Plant phenotypes are a product of genotype × environment (G × E), and the Enviratron at Iowa State University is a facility for testing under controlled conditions the effects of the environment on plant growth and development. Crop plants (including maize) can be grown to maturity in the Enviratron, and the performance of plants under different environmental conditions can be monitored 24 h per day, 7 days per week throughout the growth cycle. Results: The Enviratron is an array of custom-designed plant growth chambers that simulate different environmental conditions coupled with precise sensor-based phenotypic measurements carried out by a robotic rover. The rover has workflow instructions to periodically visit plants growing in the different chambers where it measures various growth and physiological parameters. The rover consists of an unmanned ground vehicle, an industrial robotic arm and an array of sensors including RGB, visible and near infrared (VNIR) hyperspectral, thermal, and time-of-flight (ToF) cameras, laser profilometer and pulse-amplitude modulated (PAM) fluorometer. The sensors are autonomously positioned for detecting leaves in the plant canopy, collecting various physiological measurements based on computer vision algorithms and planning motion via "eye-in-hand" movement control of the robotic arm. In particular, the automated leaf probing function that allows the precise placement of sensor probes on leaf surfaces presents a unique advantage of the Enviratron system over other types of plant phenotyping systems. Conclusions: The Enviratron offers a new level of control over plant growth parameters and optimizes positioning and timing of sensor-based phenotypic measurements. Plant phenotypes in the Enviratron are measured in situ-in that the rover takes sensors to the plants rather than moving plants to the sensors.

Öz C. sinensis yapraklarından elde edilen çayın antioksidatif ve antikarsinojenik gibi değişik farmakolojik etkileri vardır. Bitkilerin büyüme ve gelişmesi için gereksinim duyulan bor elementinin eksikliği reaktif oksijen türlerini meydana getirir. Yüksek bor konsantrasyonunun antioksidan enzim aktivitesini arttırdığı ve membran fonksiyonlarını reaktif oksijen türlerinin zararlarından koruduğu bilinmektedir. Çalışmamızın amacı; borik asit uygulanan yeşil çayın farklı dönemlerde hasat edilen yapraklarındaki biyokimyasal değişikliklerin incelenmesidir. Rize-Çayeli ilçesinde Çaykur deneme bahçesi 20 parsele ayrıldı. Gruplar, C. sinensis'e 0 (A grubu), 100 (B grubu), 300 (C grubu) ve 500 (D grubu) mg/m 2 konsantrasyonlarda borik asit uygulanarak oluşturuldu. Üç farklı hasat döneminde yeşil çay yaprakları toplandı ve sıvı nitrojende fikse edildi. Yeşil çay ekstrelerinden katalaz (CAT), süperoksit dismutaz (SOD) enzim aktivitelerinin ve glutatyon (GSH), malondialdehit (MDA) miktarlarının tayini yapıldı. SOD enzim aktivitesi ve GSH miktarı özellikle 3. hasat döneminde yüksekti, ayrıca B ve D gruplarında A grubuna göre anlamlı artış vardı (p < 0.05). MDA miktarında 1. hasat döneminde B, C ve D gruplarında, A grubuna göre bir azalma görüldü (p < 0.01). Bulgularımıza göre, yeşil çay yapraklarının yetiştiği topraklarda meydana gelen borik asit eksikliği çayın koruyucu özelliğini düşürebilir. Borik asit uygulanan bölgelerden elde edilen çay yaprakları ile antioksidan özelliğine sahip daha kaliteli ürünler elde edilebilir.
