This study was conducted in experimental fields, Department of Horticulture, University of Bagdad, in Abu-Graib  during season 2011-2012 for jerusalum artichoke. This study was included the effect of dipping tubers in three concentrations of GA3(2.5,5,10g/l) (G1,G2,G3),as well as to control treatment (G0), and spraying nutrient solution Agro leaf A1 (8g/l), as well as to control treatment (A0). This study was made by using Factorial experiment (4*2) within the design RCBD with three replicates. Results could be summarized as follows: G3A0 increased field emergence (12.00 day), G2A0 increased percentage of germination (99.33%) and G2A1 increased number of branches (4.60 stem.plant-1) but the treatment G1A1gave highest rate for number of leaves, leaf area, guide of leaf area, dry weight of the vegetative parts and dry weight of 100gm tubers as(4495.10 leaf.plant-1, 2246.20 dsm2, 99.84, 922.40g, 24.00g.) respectively. The treatments gave significant differences quantity yield, so treatment G3A0 gave highest weight of the tubers as(45.55g.) but the treatment G3A1 gave highest number of the tubers as(68.00 tuber.plant-1 ) and highest yield of plant as (2890g/plant).

Abstract Potassium (K) deficiency affects physiological performance and decreasing vegetative growth in common bean plants. However, silicon (Si) supplied via nutrient solution or foliar application may relieve nutritional stress. Thus, two experiments were carried out: initially, a test was performed to determine the best source and concentration of leaf-applied Si. Subsequently, the chosen Si source was applied via nutrient solution or via leaf to verify if it is efficient in alleviating the effects caused by K deficiency. To that end, a completely randomized 2 x 3 factorial design was used, with two levels of K: deficient (0.2 mmol L− 1 of K) and sufficient (6 mmol L− 1 of K); and Si: via nutrient solution (2 mmol L− 1 of Si) or foliar spray (5.4 mmol L− 1 of Si) and control (0 mmol L− 1 of Si). In the first experiment, foliar spraying with sodium silicate and stabilized potassium at a concentration of 5.4 mmol L− 1 was better in favoring the physiology of bean plants. In the second experiment, K deficiency without the addition of Si compromised the plant's growth. Si applied through nutrient solution or foliar spray relieved K deficiency stress, increasing chlorophylls and carotenoids content, photosynthetic activity, water use efficiency and vegetative growth.

The composition and concentration of the nutrient solution can affect growth of strawberry stock plants and runner tips production. The aim of this research was to determine runner tips production and nitrogen (N) accumulation by strawberry stock plants grown under five N concentrations in the nutrient solution and its relationships with chlorophyll meter readings. From September 2010 to March 2011, strawberry stock plants of cultivar Oso Grande and Camino Real were grown on sand polyethylene bags. Nitrogen was supplied by nutrient solutions at concentrations of 5.12 (C1), 7.6 (C2), 10.12 (C3), 12.62 (C4) and 15.12 (C5) mmol L-1. Runner tips bearing at least one expanded leaf were collected weekly and counted. The chlorophyll index (ICF) was measured fortnightly using a digital chlorophyll meter on the last second full expanded leaf of stock plant. A polynomial relationship was adjusted between the chlorophyll index and the N concentration in leaflets, which can be used for monitoring the N status of this crop. Leaflets and petioles are the organs of the strawberry stock plants with the higher N accumulation and runner tips production is not affected by N concentrations of the nutrient solution in the range of 5.12 to 15.12 mmol L-1.

Se Speciation

Selenium (Se) uptake by plants depends on its form and salicylic acid (SA) can increase the efficiency of plant biofortification in Se. This study investigated the effects of selenite (Na2SeO3) and selenomethionine (SeMet) applied individually or together with SA on a total content of Se, Se speciation forms, yield and content of sugars and ascorbic acid of lettuce, as well as activity of selenocysteine methyltransferase (smt) and methionine methyltransferase (mmt) genes of the Se metabolic pathway. Lettuce was grown in the nutrient film technique (NFT) system. Se and SA were used at doses of 0.5 and 10.0 mg dm−3 of the nutrient solution, respectively. The treatments were: 1. control, 2. Na2SeO3, 3. Na2SeO3 + SA, 4. SeMet, 5. SeMet + SA, 6. SA. Se was accumulated more in the roots than the leaves. SeMet was more effective in biofortification than Na2SeO3. SA enhanced Se uptake, especially organic Se. Plants supplied with SeMet alone or SeMet + SA accumulated in their leaves mainly SeMet and methylselenocysteine (MeSeCys), while those treated with Na2SeO3 or Na2SeO3 + SA accumulated MeSeCys and selenite (SeO3−2). The roots showed no expression of smt, while the expression of two mmt genes was independent of either Se or SA. The leaves of plants supplied with Na2SeO3 demonstrated the strongest expression of mmt and smt.

Photoperiodic Responses

Photoperiod requirements are important for optimum flower development, decreasing production time, year-round flowering, and/or for increasing vegetative growth necessary in stock plant production. The photoperiodic responses were determined for 24 vegetatively propagated specialty floral crops. Each plant species was grown at 8-, 10-, 12-, 14-, and 16-h photoperiods. Photoperiods were provided by 8 h of sunlight, then pulling black cloth and providing daylength extension with incandescent bulbs. Data collected included time to flower, flower number, and vegetative characteristics. Evolvulus nuttallianus `Blue Daze', Heliotropium arborescens `Fragrant Delight', and Orthosiphon stamineus `Lavender' were facultative short-day plants with respect to flowering. Time to flower increased as photoperiod increased. Duranta repens `Blue', Verbena hybrid `Tapien Lavender', and Verbena peruviana `Trailing Katie' were facultative long day plants with respect to flowering. Days to visible bud and first open flower decreased as photoperiod increased. Argeranthemum frutescens `Sugar Baby', Scaevola aemula `Fancy Fan Falls', and Portulaca hybrid `Apricot' had increased flower number as photoperiod increased from 8- to 16-h, although time to first flower initiation was not affected. Abutilon hybrid `Apricot', Duranta repens `Blue', Evolvulus nuttallianus `Blue Daze', Lotus berthelotii `Parrot's Beak', Lysimachia nummularia `Aurea Creeping Golden', Rhodanthe anthemoides `Milkyway', and Scaevola aemula `Fancy Fan Falls' had increased vegetative growth as photoperiod increased. All other species studied were day-neutral with regard to flowering and vegetative parameters.
