The micro-sprinkler irrigation under plastic film (MSPF) uses multiple groups of small micropores under plastic film to evenly distribute water in the root zone soil with the help of gravity and capillary suction, and the appropriate micropores group spacing and irrigation amount can realize the efficient utilization of MSPF. This study clarified the applicability of MSPF in a greenhouse and finding the optimal micropores group spacing and irrigation amount. Treatments were ranged in completely randomised design aimed to determine the effects of different micropores group spacing (L1: 30 cm micropores group spacing, and L2: 50 cm micropores group spacing) and irrigation amount [I1:0.7 Epan; I2:1.0 Epan; and I3:1.2 Epan (Epan is the diameter of 20-cm standard pan evaporation, mm)] of the MSPF on the yield and quality of tomato. The results showed that the MSPF can be used as one of the micro-irrigation methods of greenhouse, which can lead to saving water, increase yield, and improve crop quality. Compared to L2, L1 was better for fruit quality, yield, and water use efficiency (WUE). With increasing irrigation amount, the fruit shape and yield increased, but the fruit flavour, nutrition and WUE decreased. The combination of the 30 cm micropores group spacing and 1.0 Epan is recommended for greenhouse tomato under MSPF in arid and semi-arid sandy loam soil of facility agriculture.

Potato ( Solanum tuberosum L.) is one of the leading vegetable crops around the world. However, its growth, yield, and quality are reduced by several abiotic stresses such as salt stress. This study, consisted of two independent experiments was conducted to examine the effects of salt stress in potato and influence of nanoparticle-sized zinc (ZnO-NPs) in improving salt tolerance. The first experiment was conducted under in vitro conditions to evaluate the regenerated callus growth in response to the presence or absence of ZnO-NPs under different levels of NaCl (0, 17, 34, 51 and 68 mM). The second experiment was conducted using in vitro derived plantlets treated ex vitro with ZnO-NPs to evaluate its effect on tuber yield and nutritional quality under salt stress (0.0, 1.0, 2.0, 3.0 and 4.0 g L -1 ). In both experiments, ZnO-NPs were applied at 0.0 or 50 mg L -1 to three potatoes cvs. Spunta, Nicola, and Hermes raised under five levels of NaCl-induced salt stress: 0, 17, 34, 51 and 68 mM. Salt stress significantly reduced the in vitro callus growth progressively with increasing NaCl levels, while ZnO-NPs had a positive impact on growth under salt stress. Potato tubers harvested ex vitro differed significantly for calcium and iron under different levels of salt stress in response to ZnO-NPs application. The number of tubers responded negatively to increasing levels of NaCl with or without ZnO-NPs application. All three potato cultivars, grown under 34 mM NaCl, regardless of ZnO-NPs application, had a significantly higher number of tubers than when grown at other NaCl concentrations. The highest number of tubers was recorded for all three tested potato cultivars receiving ZnO-NPs under non-saline conditions, whereas the lowest number was recorded in plants under high levels of salinity, with or without ZnO-NPs. The cv. Spunta was the least affected by salt stress followed by the cv. Hermis and cv. Nicola for most traits. Application of ZnO-NPs proved effective in ameliorating the salinity-induced harmful effects on yield and quality of potato.
马铃薯(Solanum tuberosum L.)是世界上主要的蔬菜作物之一。然而，它的生长、产量和品质受到一些非生物胁迫，如盐胁迫。本研究由两个独立的实验组成，旨在研究盐胁迫对马铃薯的影响以及纳米颗粒锌(ZnO-NPs)对提高马铃薯耐盐性的影响。第一个实验在体外条件下，观察不同NaCl浓度(0、17、34、51和68 mM)下ZnO-NPs存在或不存在对再生愈伤组织生长的影响。第二项试验采用离体处理的ZnO-NPs，研究盐胁迫(0.0、1.0、2.0、3.0和4.0 g L -1)下ZnO-NPs对块茎产量和营养品质的影响。在这两个实验中，ZnO-NPs分别以0.0或50 mg L -1的浓度施用于3个马铃薯。0、17、34、51和68 mM盐胁迫下，Spunta、Nicola和Hermes的愈伤组织生长均显著降低，且随盐胁迫水平的升高，愈伤组织生长呈递减趋势，而ZnO-NPs对愈伤组织生长有正向影响。施用ZnO-NPs对不同盐胁迫下马铃薯离体收获块茎的钙和铁含量有显著影响。在施用ZnO-NPs或不施用ZnO-NPs时，块茎数量对NaCl浓度的增加呈负相关。在34 mM NaCl处理下，无论施用多少ZnO-NPs, 3个马铃薯品种的块茎数量均显著高于其他NaCl处理。在无盐条件下，施用ZnO-NPs的三个马铃薯品种的块茎数量最多，而在高盐条件下，无论是否施用ZnO-NPs，块茎数量都最少。的简历。Spunta受盐胁迫的影响最小，其次是cv。赫尔墨斯和cv。Nicola的大部分特征。施用ZnO-NPs能有效改善盐渍化对马铃薯产量和品质的影响。

Oxidative stress is a metabolic condition characterized by excessive production of free radicals in the body. The condition leads to metabolic diseases including; aging, diabetes, atherosclerosis, myocardial infarction and cancer. Antioxidants are the mainstay to modulate the consequences of oxidative damage. Secondary metabolites from lactic acid producing bacteria possess antioxidant activity. The present study aimed at isolating and identifying antioxidant metabolites present in cell free supernatant (CFS) of broth culture of Lactobacillus brevis MG 000874. Thin layer chromatography (TLC) coupled bioautography of different fractions of methanol extract of CFS using 2, 2-diphenyl-1-picrylhydrazyl (DPPH) model indicated antioxidant activity in ethyl acetate fraction. Fourier transform infrared (FTIR) spectroscopy of the isolated compound revealed the presence of aldehyde and alkyl functional groups. GC-MS analysis led to identification of four active compounds viz. a) L-proline, N-valeryl, hexyl ester b) Ergotaman-3',6',18-Trione,12'-Hydroxy-2'-Methyl-5'-(2-Methylpropyl) c) 2-Methylthiolane, S, S-Dioxide and d) Phenol, 3,5-Bis(1,1-Dimethylethyl). Findings of present study may be useful in developing antioxidant drugs from bacterial origin.
