“…Studies performed on seed-grown varieties of artichoke indicated that GA 3 effectiveness on earliness depends on sowing dates, the sensitivity of each cultivar to GA 3 and the number of GA 3 treatments (Elia et al, 1994). On the other hand, application of gibberellic acid (GA 3 ) for artichoke sown directly into the ground in warm climate conditions enforced it to flower and yield in the same year , and to obtain earlier harvest of buds by 20 days (Miguel et al, 2004). Sharaf-Eldin et al (2003) reported that exogenous GA 3 treatment, if misapplied can negatively affect plant vigor, caused elongation of early buds and produced brittle leaves that easily break.…”

“…Also, Schrader and keith (1997) found that application of 20 ppm GA3 three times at 2 weeks' intervals increased significantly the percentage of early yield. Parallel reports about the effect of GA3 on encouraging earliness of globe artichoke were, also, introduced by El-Gridly (1994), Schrader (1994) and Miguel et al (2003).…”

Two field experiments were carried out during the two successive seasons (2016 -2017 and 2017-2018), in a private Farm, at Seedy Ghazi-Kafr El Dawar, Behiera Governorate, Egypt. The objectives of this work are to evaluate the outcomes of using gibberellic acid (30 and 60 ppm), naphthalene acetic acid (25 and 50 ppm),6-N benzyl adenine purine (20 and 30 ppm) and seaweed extract (1 and 2 g / L) on growth, yield and quality of globe artichoke cv. 'French' and 'Balady' under Behiera Governorate environment. The obtained results of the two seasons revealed that French cultivar showed higher mean values of plant height, number of leaves, leaf area, number of branches, fresh and dry weight, nitrogen and protein in leaves. However, Balady cultivar showed high values of number of early head / plant and number of early head /feddan, total head / plant, number of total head /feddan, weight of edible part/ plant and potassium in leaves. Spraying artichoke plant suing gibberellic acid, naphthalene acetic acid, N-6-benzyle amino purine and seaweed extract with all concentrations showed significant effect on the almost vegetative growth characteristics, yield and its components and chemical characteristics of leaves with different magnitude compared to control treatment. In this respect, gibberellic acid was superior in the case of vegetative growth and early yield characteristics. However, seaweed extract and 6-N benzyl adenine purine gave the highest mean values of total yield and chemical characteristics of leaves. The combined treatment of Balady cultivar and either seaweed extract at 2 g / L or N-6-benzyle amino purine at 30 ppm recorded the maximum mean values of the studied characters and might be considered as an optimal treatment for the production of high yield and good quality of globe artichoke plants.

“…El injerto puede ser una estrategia de adaptación en sistemas agrícolas de producción orgánica o integrada que permite a las plantas inducir la resistencia o tolerancia a enfermedades transmitidas por patógenos del suelo y estreses ambientales [7]. El cultivo de plantas injertadas se ha extendido ampliamente (principalmente en tomate, melón y sandía), pero esta práctica está aún limitada en pimiento [8] y en lo que respecta a la información existente sobre patrones de pimiento tolerantes a estrés hídrico. El objetivo del trabajo fue estudiar el efecto paliativo que ejerce el injerto sobre el estrés hídrico.…”

el cultivo se realiza desde diciembre hasta agosto, centrándose la producción en los meses donde se dan altas temperaturas y radiaciones en el interior de los invernaderos, por lo que el cultivo tiene una gran demanda de agua. El objetivo de este estudio fue estudiar el efecto paliativo que ejerce el injerto sobre el estrés hídrico. Se utilizaron plantas de la variedad Gacela y Gacela injertada sobre sí misma. En general, el uso del injerto mejoró los parámetros vegetativos y los fotosintéticos e incrementó el rendimiento de las plantas injertadas en relación a las que no se injertaron. Estos resultados sugieren que las plantas injertadas han mostrado un incremento en la absorción de agua y nutrientes y tolerancia a este estrés abiótico, por lo que podemos concluir que el injerto es una eficaz herramienta agrícola que mejora los parámetros vegetativos y de producción frente a un estrés hídrico.
