Abstract:
A pot experiment was conducted in greenhouse and nursery at Ornamental Farm Faculty of Agriculture, Suez Canal University, Ismailia Governorate Egypt, during the two seasons of 2018 and 2019. The aim of this work is to study the effect of different treatments of Hyper feed Nano-fertilizer NPK (19:19:19) Nano-fertilizer rates (0, 1.5, 3.0, 4.5 g/L) added every 15 days with irrigation water drench on the pot with 400 m/L and monthly foliar application with Gibberellic acid (GA3) at (0, 100, 200 and 300 ppm) either alone or in combination from the 1st of May to the 1st of October on the vegetative growth and some chemical constituents of Codiaeum variegatum (L.) cv. Gold dust plants. The results showed that Nano-fertilizer plus GA3 was the most effective compound to improving all growth parameters of Codiaeum plants, followed by Nano-fertilizer, while GA3 was the second in order. Among Nano-fertilizer treatments, the highest level of Nano-fertilizer at 4.5 g/L was optimum for growth of Codiaeum plants. Nano-fertilization every 15 days with Hyper feed Nano-fertilizer NPK (19:19:19) at 4.5 g/l combined with foliar spray of both GA3 at 300 ppm resulted in the highest significant values for plant height, stem diameter, number of leaves/plant, leaf area and fresh and dry weights of plant, fresh and dry weights of leaves, stems and roots/plant. Data also showed that the previously mentioned combination resulted in the highest contents of N, P, K, Total carbohydrates, and Total chlorophyll in Codiaeum leaves.

Abstract:
Two pot trials were carried out during the two successive Winter seasons of 2015/2016 and 2016/2017 at private commercial nursery, Damanhour city, El-Beheira Governorate, Egypt under greenhouse conditions. The objective of these experiments was to study the effect of foliar application with each of salicylic acid (SA) (50 and 100 mgL-1), triacontanol (TRIA) (25 and 50 mgL-1) and δ-aminolevulinic acid (ALA) (25 and 50 mgL-1) on Viola wittrockiana Gams L. (Blue with Blotch cultivar) grown under different concentrations of salinity (0, 20, 40 and 60 mM of NaCl). Generally, the tested materials were varied in their significant effects on studying characters. The obtained results of the two seasons indicated that increasing salinity levels from 20 to 60 mM significantly reduced all studied parameter levels, i.e., plant height, branches number per plant, shoot dry weight per plant, leaf area, root length and root dry weight, nitrogen, phosphorus, potassium, calcium, magnesium, and chlorophyll contents. While Na+ and Cl- were increased relative to control. Also, the results indicated that the salicylic acid, δ-aminolevulinic acid, and triacontanol significantly increased plant growth and chemical traits, as well as reduced the contents of Na+ and Cl- compared to the control (distilled water only) treatment. Application of triacontanol (25 mgL-1) or salicylic acid (50 mgL-1); improved vegetative, flowering, root growth and leaves chemical composition under salt stress during both seasons. Triacontanol enhanced salinity tolerance in both seasons by increasing proline accumulation. Under each salinity level, triacontanol (25 mgL-1) was the most effective treatment for mitigating the deleterious effect of salt stress in pansy plants

Abstract:
Field experiments were carried out at the Experimental Farm of El-Kassasin Horticultural Research Station, Ismailia Governorate, Egypt, during two successive seasons (2017-2018 and 2018-2019). To evaluate the effect of cold storage periods (1, 2, 3, 4, 5-weeks at 5°C beside room temperature as control) and bulb weight (100, 150 and 200±5 g) of Narcissus tazetta L. cv. Cheerfullness bulbs on growth, flowering, bulbs production, leaf minerals content and some bulb active ingredients. The results showed positive effects of cold storage and bulb weight as well as the interaction between them on growth, flowering and bulbs production. The highest values of vegetative growth, flower quality and early flowering, bulb yield and mineral content of dry leaves were obtained by the interaction between the longest periods of cold storage (5-weeks) with the highest bulb weight (200 g). Whereas higher values of active ingredients in dry bulbs, especially antioxidant activity were recorded by the interaction between the cold storage period of two weeks with weights 150 and 100 g/bulb. These results were recorded in both seasons. All treatments gave differences in essential oil components of flowers.
