“…The interaction between ABA and PAs during seed maturation and germination had also been studied in detail [4, 6, 26]. ABA treatment obviously enhanced Put and Spm but decreased Spd content in wheat seeds [33].…”

“…Of which, SPDS catalyzes Spd synthesis; while cyclohexylamine (CHA), a polyamines biosynthesis inhibitor, inhibits directly the SPDS activity and leads to the decrease of Spd content. PAs are usually metabolized by diamine oxidase (DAO) and polyamine oxidase (PAO) [4]. Hydrogen peroxide (H 2 O 2 ) is produced in the oxidation of PAs by DAO and PAO, which is considered to be necessary for plant-developmental processes [3, 43] .…”

Exogenous spermidine improves seed germination of sweet corn via involvement in phytohormone interactions, H2O2 and relevant gene expression

BackgroundThe low seed vigor and poor field emergence are main factors that restricting the extension of sweet corn in China. Spermidine (Spd) plays an important role in plant growth and development, but little is known about the effect of Spd on sweet corn seed germination. Therefore the effect of exogenous Spd on seed germination and physiological and biochemical changes during seed imbibition of Xiantian No.5 were investigated in this study.ResultsSpd soaking treatment not only improved seed germination percentage but also significantly enhanced seed vigor which was indicated by higher germination index, vigor index, shoot heights and dry weights of shoot and root compared with the control; while exogenous CHA, the biosynthesis inhibitor of Spd, significantly inhibited seed germination and declined seed vigor. Spd application significantly increased endogenous Spd, gibberellins and ethylene contents and simultaneously reduced ABA concentration in embryos during seed imbibition. In addition, the effects of exogenous Spd on H2O2 and MDA productions were also analyzed. Enhanced H2O2 concentration was observed in Spd-treated seed embryo, while no significant difference of MDA level in seed embryo was observed between Spd treatment and control. However, the lower H2O2 and significantly higher MDA contents than control were detected in CHA-treated seed embryos.ConclusionsThe results suggested that Spd contributing to fast seed germination and high seed vigor of sweet corn might be closely related with the metabolism of hormones including gibberellins, ABA and ethylene, and with the increase of H2O2 in the radical produced partly from Spd oxidation. In addition, Spd might play an important role in cell membrane integrity maintaining.Electronic supplementary materialThe online version of this article (doi:10.1186/s12870-016-0951-9) contains supplementary material, which is available to authorized users.

“…Abscisic acid (ABA) is an essential hormone that regulates crop responses to various environmental challenges including drought, salt and cold stresses . In grape berries, ABA has been considered to promote ripening and also regulate several processes concerning anthocyanin biosynthesis in coloured cultivars . Most of the work on PRD irrigation in grapevine has focused on the effects of root‐to‐shoot ABA signalling on stomatal aperture and leaf expansion, which may limit vegetative growth thereby favouring reproductive growth but without signal penetration into the fruit .…”

“…Most of the work on PRD irrigation in grapevine has focused on the effects of root‐to‐shoot ABA signalling on stomatal aperture and leaf expansion, which may limit vegetative growth thereby favouring reproductive growth but without signal penetration into the fruit . This hypothesis is supported by the observation that xylem transport to berries decreases after veraison . Nevertheless, different irrigation techniques can alter ABA concentrations measured in berries, which may alter berry quality.…”

Long‐term impact of deficit irrigation on the physical quality of berries in ‘Crimson Seedless’ table grapes

Only NI clusters showed lower quality than their irrigated counterparts. Neither RDI nor PRD had any noticeable effect on berry quality at the end of cold storage and shelf-life, with the slight differences detected between these treatments related to stem browning and dehydration. Sensory results were similar in RDI and PRD, which provided grapes that were more acceptable to consumers than the control. Thus, it is possible to decrease irrigation of table grapes without adversely affecting the physical quality of the berries.

“…Partial root-zone drying also has significant effects on secondary metabolites that are of special interest as phytochemicals responsible for quality-or health-related characteristics and antioxidants of fruits/grains. Results of Antolín et al (2006Antolín et al ( , 2008 showed that under PRD changes in ABA content improved berry quality by increasing anthocyanin content and that increased mRNA induced accumulation of genes responsible for anthocyanin biosynthetic pathway (Jeong et al, 2004). According to Romero et al (2016) reduced vegetative growth and increased light penetration into the canopy in PRD vines together with the increased ABA content and salicylic acid (in berries at harvest) might have an increasing effect on production of phenolic compounds which have a different roles (as antioxidants, stabilizators of anthocyanins, for wine color, etc).…”

Due to climate changes and increased demands of different water users (agriculture, industry, domestic) water becomes scarce resources worldwide. Since irrigated agriculture is the one of the largest consumer of these resources (so-called blue water footprint), irrigation management must be shifted from maximal production per crop area to maximal production per unit of water used by crops. Among the strategies for reducing water footprints, changing the full irrigation to the reduced crop's water supply (deficit irrigation techniques) is one of the options. In this mini-review, we present the latest advances of partial root-zone drying (PRD) applications in different agricultural plants, with the special emphases on the PRD effects on increasing WUE, yield and yield quality. We describe two PRD practical approaches (alternate and fixed), background of PRD induced increase in yield and water use efficiency and improved understanding about nutrient use efficiency. The evidence of PRD effect on the increase in nutritional and health attributes of yield in different species is also presented. Because of limited available data, further research is needed to understand complex biosynthetic pathway and synthesis of nutritive-and health-related metabolites and antioxidants in PRDtreated plants. Practical application and promotion of this knowledge will allow farmers in water scarce areas to adapt PRD not only as a strategy for saving water, improving nutrient use and increase/sustain yield, but also for producing food with enhanced nutritive and health characteristics.
