“…This result is mainly linked to the bigger size of the leaves in T2 in the first part of the crop cycle, thus promoting the photosynthetic activity. This confirms that the high artichoke leaf area positively influenced the photosynthesis activity, as already reported [50].…”

Effect of Vegetative Propagation Materials on Globe Artichoke Production in Semi-Arid Developing Countries: Agronomic, Marketable and Qualitative Traits

Abstract:In Tunisia, globe artichoke is mainly propagated by underground dormant axillary buds (ovoli), which are removed from the field in August during the quiescence period. The high cost of in vitro-plants and the absence of specialized nurseries were among the reasons for the rise of heterogeneity and spread of diseases. The aim was to help farmers to improve artichoke yield and quality by ameliorating their vegetative propagation technique with low cost methods. Three plant cuttings management methods were tested: summer ovoli (T0); spring offshoots nursery's cuttings forced to pass a vegetative rest period by stopping irrigation (T1); and offshoots nursery's cuttings not forced (T2). The cuttings management can affect both yield and qualitative traits of artichoke. T1 nursery plants produced the heaviest primary heads, 7% and 23% higher than T2 and T0, respectively. T1 plants exhibited the highest yield during the harvest season, with +17.7% and +12.2% compared to T0 and T2, respectively. T0 and T1 showed the highest total antioxidant capacity and inulin content; the propagation method also affected the short-chain sugars ratio. T1 is a viable and sustainable alternative to the traditional one that does not heavily impact on growing costs and improves yield and quality of artichoke.

“…Reports suggested that GA has shielding effects against metal toxicity (Maggio et al, 2010). Similarly exogenous GA3 application increases salicylic acid (SA) biosynthesis (Halter et al, 2000) that plays important role in plant defense. Gangwar et al (2011) reported that exogenous application of GA3 improves plant growth by regulating the endogenous levels of stress related phytohormones (ABA, ethylene).…”

Abiotic stress prevents plants from absorbing available nutrients resulting in yield loss and soil contamination. Growth regulators like gibberellic acid (GA) may improve plant growth under stress conditions. This study was conducted to evaluate the role of GA on the rice performance under saline conditions and to investigate its effects on regulatory gene expression by GA-mediated seed priming. Seeds of rice variety KSK 282 were primed in GA solution (0, 50, 100 and 150 ppm) and grown under different salt (NaCl) concentrations (0, 50, 100 and 150 mM). Increase in salt concentration led to decrease in rice growth. GA priming reversed the negative effects of salt stress and enhanced different growth attributes like germination, seedling growth and weight, while decreased the concentration of toxic ions such as Na + in some treatments. However, GA priming was not very effective on Chlorophyll a, b (Chl-a, Chl-b) and total carotene contents. Reverse transcription polymerase chain reaction (RT-PCR) approach was used to study the effect of GA-mediated seed priming on the expression of two stress responsive genes, OsZat 12-1 (LOC_Os01g62130 also called ZOS1-14 -C2H2 zinc finger protein) and OsZat 12-9 (LOC_Os01g62190 also called ZOS1-15 -C2H2 zinc finger protein). There was no or very low expression of OsZat 12-1 and OsZat 12-9 in hydroprimed seeds under all salt stress conditions tested, while induction of gene expression was observed for plants raised from GA primed seeds under salt stress. In conclusion, GA regulated the growth at early stages of rice life cycle by inducing regulatory genes expression; therefore it is noteworthy that while studying salinity factor, the induction of genetic determinants (genes) by plant growth regulators should also be considered.

“…Phytohormones also known as plant growth regulators (PGRs) are the main players for regulation of plant growth and development (Khalid et al, 2001;Ghaafar and Rawi, 2011;Sabir et al, 2013). They are key for plants to respond an ever changing environment and external stimuli (Halter et al, 2005) and mediate plant growth in their specific synergistic and/or antagonistic cross-talk (Ali et al, 2013;Gangwar et al, 2011). In response to abiotic stresses biosynthesis of abscisic acid (ABA) increases while the level of cytokinin (CK) and gibberellins (GA) decreases (Veselov et al, 2003).…”

“…Gibberellic acid (GA 3 ) helps the plants to adapt abiotic stresses and has shielding effects against metals toxicity (Tuna et al, 2008;Maggio et al, 2010). Exogenous application of GA 3 increases the biosynthesis of salicylic acid (SA) and improves abiotic stress tolerance of plant which could be correlated with increased endogenous levels of SA (Gangwar et al, 2011;Halter et al, 2005). Exogenously applied GA 3 improves plant growth and development by modulating the endogenous levels of stress responsive phytohormones i.e.…”

). Two sets of Ni contamination levels were maintained, one set was kept without application of GA 3 while in second set 10 -4 M GA 3 was applied as foliar spray at 15, 30 and 45 days after germination. Significant reduction in all growth and yield attributes of mungbean was recorded in Ni contaminated pots. However, application of GA 3 enhanced the length, fresh and dry weight of shoots and roots as well as grain yield of mungbean in Ni contamination. Moreover, Ni concentration was increased in roots and shoots of mungbean with increasing levels of Ni contamination from 0 to 60 mg kg -1. But, application of GA 3 caused significant decrease in Ni concentration in roots and shoots of mungbean in Ni contaminated soil. It is concluded that use of GA 3 could be very effective to improve plant growth through reduced Ni uptake by plants in the Ni contaminated soils.
