In order to evaluate the effects of gibberellic acid and vermicompost on growth and flowering of daffodil flower, a factorial experiment has been conducted under greenhouse conditions, based on completely randomized design with 12 treatments and three replications and four samples in each replication. The first factor involves vermicompost in four levels, namely 0 (control), 10%, 15%, and 20% of potted soil (V/V) and the second factor, three levels of gibberellic acid, 0 (control), 150, and 300 mg/L, all applied by dipping the bulbs for 48 hours. Results of analysis variance of the data show that the impacts of gibberellic acid and vermicompost on most traits such as leaf area, vase life, number of leaves, chlorophyll index, TSS, leaf phosphorus, and leaf potassium have displayed significant effects (P<0.01), compared to the control. Also gibberellic acid and vermicompost have had significant impacts (P<0.01) on carotenoid (0.28 mg.g-1Fw), leaf nitrogen (2.07%), root fresh weight (11 g), root dry weight (1.1 g), and stem diameter (8.11 mm). Also, the duration of flowering stem appearance has had significant effects (P<0.05). This study’s results show that the application of vermicompost at 20% level and gibberellic acid with a concentration of 300 mg/L have improved the growth and accelerated flowering with an average of 10 days, increasing the vase life of flowers with an average of four days with a noticeable difference, compared to the control.

Abstract
The purpose of the present study is to evaluate the effects of different levels of vermicompost on quantity and quality of Lilium longiflorum LA hybrid cv. Dynamix, in a completely randomized design with 5 treatments and 3 replications. The treatments include 0 (control), 20%, 35%, 50%, and 65% of vermicompost ...

The purpose of the present study is to evaluate the effects of different levels of vermicompost on quantity and quality of Lilium longiflorum LA hybrid cv. Dynamix, in a completely randomized design with 5 treatments and 3 replications. The treatments include 0 (control), 20%, 35%, 50%, and 65% of vermicompost pot (V/V) in 70% cocopeat and 30% perlite of bed culture under greenhouse conditions. Once the buds’ color change from bold green to colorless green, cut flowers are removed from various treatments and the flower’s inflorescence is studied in the laboratory. Results show that fresh weight of Lilium in low-level vermicompost surpass the other treatments, especially the 20% one. Qualitative parameters such as chlorophyll, protein leaf, anthocyanin, and total soluble solid of the petal have had a significant increase in all vermicompost treatments, compared to the control. Overall result examination of this study indicates the 20% vermicompost treatment has been more suitable, thanks to its superior moisture preservation at plant shoots as well as the improvement of some morphologic traits like the number of flowers as well as addition of leaf area, which contributes to the cultivation of better quality Lilium LA hybrid flower.

The effects of grafting under conditions of deficit irrigation, on content of minerals leaf and root, evalutate in a field experiment under deficit irrigation was conducted with Split plot in a randomized complete block design with three replications, in the research field of higher education institution Imam Khomeini (RA) under the Ministry of Agriculture in Karaj, during 2014. In this study, a landrace melon from Inodorus group (Zard-e-Jalali) as the scion and commercial varieties of Cucurbita rootstocks cv., ‘Shintozwa’and ‘Ferro-RZ’was used as the rootstock. Grafted melons upon commercial varieties of Cucurbita with own-rooted and ungrafted at three irrigation levels 60, 80 and 100 percent based on total available water depletion with drip irrigation system were evaluated. Comparison of means showed that maximum (40.76 ton.ha-1) and minimum (31.16 ton.ha-1) total yield, related to ‘Shintozwa’rootstock and self grafted respectively. The results showed that the irrigation levels and rootstocks had a significant effect (P <0.01) on Leaf and root mineral concentration. Also, content of minerals of leaves and roots decreased with increasing water stress. There was not significant difference in the level of 5 percent, in relation to total nitrogen of leaf between ‘Shintozwa’and ‘Ferro-RZ’rootstocks.The comparison of means showed highest (2.97 percent on a dry matter basis) and the lowest leaf total nitrogen (2.23 percent on a dry basis), respectively, in plants that grafted on ‘Shintozwa’and own rooted. The percent increase in leaves mineral elements, contain nitrogen, phosphorus, potassium and zinc in Zard-e-Jalali grafted upon ‘Shintozwa’ rootstock in compared to ungrafted plants was 26.92, 13.15, 17.88 and 15.76 percent, respectively.
