“…Regarding IS, fully irrigated plants showed the highest RWC and MSI during the whole growing period (T1), while the lowest values in each phase were obtained for the strategies that reduced the water applied in the corresponding phase, particularly at severe levels (50% of the IWR). The RWC and MSI obtained in this study were in agreement with those reported by Wu et al [49] and Latif et al [23]. The differences in RWC and MSI, between the full irrigation strategy (T1) and the most restricted CDI (T3), could explain the reduction that the CDI causes in the growth and MY.…”

“…Bozkurt et al [21], and Souza et al [22] studied different irrigation levels below, and above, optimum irrigation.They obtained the highest yield with full irrigation, while excess water applications had a negative effect on the yield of cauliflower. According to Latif et al [23], water stress reduced plant growth, leaf chlorophyll concentration, relative water content, and protein content of cauliflower cultivated under net-house conditions in Iran.…”

Water shortage is one of the major constraints in vegetable production. Deficit irrigation is a sustainable technique that improves irrigation water use efficiency. Field studies were conducted during two growing seasons to evaluate the effects of deficit irrigation on plant growth, plant water status, productive response (curd yield and quality), irrigation water use efficiency (IWUE), and crop profitability of cauliflower. Nine irrigation treatments were used, applying 100%, 75% (moderate), or 50% (severe) of the irrigation water requirements (IWR) during the entire growing season (Continued Deficit Irrigation, CDI), or 75% and 50% of IWR during one of the following stages (Regulated Deficit Irrigation, RDI): Juvenility, curd induction, and curd growth. Severe deficit irrigation applied during juvenility and curd induction reduced the plant size, but it only led to a significant reduction of marketable yield (22%), and average curd size and weight if it was maintained throughout the crop cycle, supposing the highest IWUE (43.6 kg m−3). Moderate CDI or severe RDI during juvenility did not reduce significantly the curd yield compared to fully irrigated plants (4.4 kg m−2), thereby obtaining similar gross revenues (16,859 € ha−1) with important water savings (up to 24.3%), improving IWUE (up to 34.2 kg m−3).

“…Efforts are underway to develop new tools for understanding possible mechanisms related to stress tolerance and identification of stress tolerance traits for promoting sustainable agriculture (Cramer et al, 2011; Fiorani and Schurr, 2013). Basic tolerance mechanisms involve the activation of different stress-regulated genes through integrated cellular as well as molecular responses (Latif et al, 2016). Plants respond to their immediate surroundings in diverse ways, which assist the cells to adapt and achieve cellular homeostasis manifested in phenotypes of plants under particular environment (James et al, 2011).…”

Mungbean [Vigna radiata (L.) R. Wilczek var. radiata] is an important food and cash legume crop in Asia. Development of short duration varieties has paved the way for the expansion of mungbean into other regions such as Sub-Saharan Africa and South America. Mungbean productivity is constrained by biotic and abiotic factors. Bruchids, whitefly, thrips, stem fly, aphids, and pod borers are the major insect-pests. The major diseases of mungbean are yellow mosaic, anthracnose, powdery mildew, Cercospora leaf spot, halo blight, bacterial leaf spot, and tan spot. Key abiotic stresses affecting mungbean production are drought, waterlogging, salinity, and heat stress. Mungbean breeding has been critical in developing varieties with resistance to biotic and abiotic factors, but there are many constraints still to address that include the precise and accurate identification of resistance source(s) for some of the traits and the traits conferred by multi genes. Latest technologies in phenotyping, genomics, proteomics, and metabolomics could be of great help to understand insect/pathogen-plant, plant-environment interactions and the key components responsible for resistance to biotic and abiotic stresses. This review discusses current biotic and abiotic constraints in mungbean production and the challenges in genetic improvement.

“…Azzedine et al (2011) reported that the free-radical scavenging activities of catalase (CAT) and superoxide dismutase (SOD) could be stimulated by exogenous AsA application. Moreover, AsA could increase endogenous osmolyte synthesis of proline and glycinebetaine in plant cells (Latif et al, 2016). These results demonstrated the role of AsA in minimizing and eliminating possible damage due to oxidative stress.…”

Adding Ascorbic Acid to Reduce Oxidative Stress During Cryopreservation of Somatic Embryos of <i>Paphiopedilum niveum</i> (Rchb.f.) Stein, an Endangered Orchid Species

Paphiopedilum niveum (Rchb.f.) Stein, an endangered species, has been listed in CITES Appendix I and its germplasm conservation is required. To improve the regeneration of cryopreserved somatic embryos (SEs), adding 0.1 mM ascorbic acid (AsA) at a critical step during cryopreservation was investigated. The reactive oxygen species (ROS) and malondialdehyde (MDA) contents were also assessed during five steps (preconditioning, 1 st preculture, 2 nd preculture, osmoprotection, and dehydration) of a developed V cryo-plate technique as described briefly. Two-month-old SEs were preconditioned on modified Vacin and Went medium (MVW) containing 0.1 M sucrose for seven days. These SEs were precultured on MVW containing 0.2 M sucrose for one day (1 st preculture) before being transferred to the same medium with 0.6 M sucrose for one day (2 nd preculture). Precultured SEs were embedded on a cryo-plate, incubated in loading solution (LS) with 1.2 M sucrose for 30 min at 25°C and dehydrated with plant vitrification solution 2 (PVS2) for 60 min at 25°C. It was found that applying AsA on day 7 after culture (before the 1 st preculture) could reduce total ROS and MDA levels, leading to a high regeneration percentage (39%) of cryopreserved P. niveum SEs.
