“…Under shade stress and Cd toxicity, the activities of superoxide dismutase (SOD), catalase (CAT) and peroxidase (POD) were increased in watermelon seedlings and oilseed rape by ALA (Sun et al 2009;Ali et al 2013a). In the research of rice seedlings under cold stress (10 °C), the activities of SOD, POD, ascorbate peroxidase (APX) and glutathione peroxidase (GPX) were boosted by soaking ALA (8.5 mM) during seed germination (Sheteiwy et al 2017). Studies toward genome level suggested that 1 mg/L ALA up-regulated the expression of POD, CAT, APX of oilseed rape (B. napus L.) under water-deficit condition and cucumber (C. sativus L.) seedlings under NaCl condition (Liu et al 2011;Zhen et al 2012).…”

Crop productivity is restricted by various abiotic stresses such as drought, salinity, heat, and cold. Many efforts have been taken to decrease the inhibition of plant growth by alleviating the abiotic stresses. Exogenous applications of hormones, plant growth regulators, and/or small signaling molecules have been reported as a means to enhance plant resistance to stress. One of the small signaling molecules utilized is 5-aminolevulinic acid (ALA) that has been shown to enhance plant growth under abiotic stress. As a metabolic intermediate in higher plants, ALA is a precursor of all tetrapyrroles such as chlorophyll, heme and siroheme. The pathway towards biosynthesis upstream and the metabolism downstream of ALA contains multiple regulatory points that are affected by positive/negative factors. However, report about the regulatory aspects of the ALA metabolic pathway and the role of ALA in stimulating physiochemical processes in higher plants under stress have not been collated and summarized systematically. In this regard, we summarize recent developments in understanding the mechanisms of plant responses to abiotic stress which are affected by ALA as well as new information on the metabolic pathway of ALA. We find that exogenous application of ALA can enhance some key physiological and biochemical processes in plants such as photosynthesis, nutrient uptake, antioxidant characteristics and osmotic equilibrium, however, more in-depth research on the specific mechanisms are needed.

“…Improvement of maize LTGA could help farmers to sow early, which has advantages in earlier harvest and longer plant life cycle: earlier harvest could extend maize growth region to higher altitudes and longer life cycle increases biomass accumulation and yield output ( Frascaroli and Landi, 2017 ). Although seed LTGA could be improved by agronomic practices, such as seed priming or plastic sheeting ( Li et al, 2017 ; Sheteiwy et al, 2017 ), the most economical and reliable method is to breed low-temperature tolerance cultivars aided by marker assisted selection (MAS). Recently, researchers identified various QTL associated with low temperature tolerance in maize ( Fracheboud et al, 2004 ; Presterl et al, 2007 ; Rodriguez et al, 2008 ; Hu et al, 2016 ; Shi et al, 2016 ), but little is known about germination stage.…”

Improving seed vigor in response to cold stress is an important breeding objective in maize that allows early sowing. Using two cold tolerant inbred lines 220 and P9-10 and two susceptible lines Y1518 and PH4CV, three connected F2:3 populations were generated for detecting quantitative trait locus (QTL) related to seed low-temperature germination ability. At 10°C, two germination traits (emergence rate and germination index) were collected from a sand bed and three seedling traits (seedling root length, shoot length, and total length) were extracted from paper rolls. Significant correlations were found among all traits in all populations. Via single-population analysis, 43 QTL were detected with explained phenotypic variance of 0.62%∼39.44%. Seventeen QTL explained more than 10% phenotypic variance; of them sixteen (94.12%) inherited favorable alleles from the tolerant lines. After constructing a consensus map, three meta-QTL (mQTL) were identified to include at least two initial QTL from different populations. mQTL1-1 included seven initial QTL for both germination and seedling traits; with three explaining more than 30% phenotypic variance. mQTL2-1 and mQTL9-1 covered two to three initial QTL. The favorable alleles of the QTL within these three mQTL regions were all inherited from the tolerant line 220 and P9-10. These results provided a basis for cloning of genes underlying the mQTL regions to uncover the molecular mechanisms of maize cold tolerance during germination.

“…Seed priming has been frequently used to improve seed germination and seedling development and can also improve plant growth in a wide range of environmental conditions [30][31][32][33][34][35]. As a priming agent, humic acid (HA) are usually used as a kind of hormone that promotes plant growth rather than improving the chemical or the physical conditions of the soil.…”

Expanding eco-friendly approaches to improve plant growth and crop productivity is of great important for sustainable agriculture. Therefore, a field experiment was carried out at the Faculty of Agriculture Farm, Mansoura University, Egypt during the 2018 and 2019 growing seasons to study the effects of different bio- and organic fertilizers and their combination on hybrid maize growth, yield, and grain quality. Seeds were treated with Azotobacter chrocoocum, arbuscular mycorrhizal fungi (AMF), Bacillus circulans, biogas slurry, humic acid (HA), and their combination aiming to increase the growth and yield of maize and to reduce the need for chemical fertilizers. The results showed that combined application of the biofertilizer mixture (Azotobacter chrocoocum, AMF, and Bacillus circulans) with organic fertilizers enhanced maize growth, yield, and nutrient uptake. Moreover, the bio-organic fertilization has improved the soluble sugars, starch, carbohydrates, protein, and amino acid contents in maize seeds. Additionally, the bio-organic fertilization caused an obvious increase in the microbial activity by enhancing acid phosphatase and dehydrogenase enzymes, bacterial count, and mycorrhizal colonization levels in maize rhizosphere as compared with the chemical fertilization. Additionally, the bio-organic fertilizers has improved α-amylase and gibberellins (GA) activities and their transcript levels, as well as decreased the abscisic acid (ABA) level in the seeds as compared to the chemical fertilizers. The obtained results of bio-organic fertilization on the growth parameters and yield of maize recommend their use as an alternative tool to reduce chemical fertilizers.
