Coccidiosis of chickens, caused by species of Eimeria (Protozoa, Apicomplexa), is an intestinal disease of major economic importance worldwide. In the present study, the reproductive characteristics of a precocious line (designated E. tenella Rt3+15) from Australia were investigated in chicken embryos and the implications of the findings briefly discussed.
A study was carried out at the Department of Horticulture, KNUST from 8th January, 2017 to 17th March, 2017 to determine the best propagating medium for Ixora coccinea and Ficus pumila. The design was a Complete Randomized Design with four treatments replicated three times. The treatments were; topsoil only, biochar only, mixture of topsoil and biochar (1:1) and mixture of topsoil and biochar (2:1) . The study revealed that the treatment with the mixture of topsoil and biochar (2:1) was the best medium, in terms of physical and chemical properties and produced the highest number of leaves and rooted cuttings in Ficus pumila. Topsoil only had highest number of leaves and roots for Ixora coccinea. The biochar medium started rooting earlier for Ficus pumila at 2 weeks and recorded the highest number of leaves, while that of Ixora coccinea rooted at the fourth week towards the fifth week. The study concluded that mixture of topsoil and biochar (2:1) could be used for propagating difficult to root ornamental plants whiles Biochar only could also be used to propagate Ficus pumila.
This research was conducted to determine the effects of three grafting methods (chip budding, side and splice grafting) and topical applications on graft scion of IBA (0 and 4000 ppm) and three plant growth promoting rhizobacteria (PGPR) strains (Bacillus subtilus-OSU142, Bacillus megatorium-M3 and Burkholderia gladia-BA7) on graft success and plant growth in black mulberry sapling production. The experiment was carried out in a randomized complete block design with three replications in Bolu, Turkey in 2014 and 2015. The black mulberry (Morus nigra L.) were used for grafting scions. Twoyear old white mulberry (Morus alba L.) seedling were used for rootstocks. The results showed that in general all of the bacterial strains and IBA had significant effects on all parameters tested in graft scion compared with the control. Application of 4000 ppm IBA and Bacillus megatorium-M3 increased the success graft take rate (74.44 and 72.22%, respectively), graft sprouting rate (61.11 and 60.00%, respectively), graft shoot diameter (6.21 and 5.70 mm, respectively) and graft shoot length (35.50 and 35.31 cm, respectively). Grafting methods had significant effect for all parameters and grafting methods increased the graft success. The best graft take rates (75.33 and 70.67%, respectively), graft sprouting rates (62.67 and 57.33% respectively), graft shoot diameter (5.56 and 5.88 mm, respectively) and graft shoot length (34.14 and 37.86 cm, respectively) were obtained from splice grafting and chip budding methods. In conclusion, the present study showed that 4000 ppm IBA and PGPR strains (especially M3 and OSU142) increased the graft success of black mulberry graft. The PGPR application may be of benefit for grafting in mulberry cultivars, particularly for organic farming. Besides, splice grafting and chip budding were found to be successful to black mulberry plant production.
There is inadequate information in the case of rootstock application in pomegra­nate. In this study, propagation of pomegranate was investigated using bench grafting. The experiment was conducted as factorial in the framework of CRD design with three replications. The rootstocks were Rb R2 and R3 and the scions included 'Gorj-e- Dadashi' (Si) and 'Gorj-e-Shahvar' (S2). At the end of experiment, successful callus formation at graft union, bud take percentage (BT), bud take stem length, internodes length and shoot fresh and dry weight were measured. The results indicated that roots- tock influenced all measured characters including bud take and consequently the highest and lowest BT were obtained in Ri and R3, respectively. The interaction be­tween rootstock/scion indicated the highest BT in R3Si and R2S2.
Grafting plays an important role in rhododendron propagation. Successful graft union depends on selection of a suitable stock, grafting season, and method. In this study, three methods (whip, cleft, and side grafting) were compared in two seasons. The stocks were mainly cuttings of R. catawbiense-Hybridum, R. ‘Cunningham's White', but also R. pachytrichum and R. brachycarpum. Scions were taken from several cultivars deriving from R. catawbiense. To shorten the production period, scions were grafted on unrooted stocks, and the results are encouraging. The best stock was R. ‘Cunningham's White', especially when side grafting was applied in spring.
