Effect of vermicompost on vegetative growth and nutrient status of acclimatized Grand Naine banana plants.

Novel approach for introducing vermicompost as an acclimatization soil for banana plants was conducted. Different potting mixture of vermicompost, vermiculite, peatmoss and sand at different ratios were used to study the effect of different agricultural media on vegetative growth and leaf mineral content of banana tissue culture plantlets, after acclimatization stage. Two different trial periods were studied; 12 and 24 weeks in these agricultural media for two seasons. Results indicated that using vermicompost combined with vermiculite and sand (33.3% for each) recorded the best results for the most vegetative growth studied parameters (plant height, plants and roots length, stem diameter, leaf width and shoot and root fresh and dry weight). Moreover, vermicompost at 50% + peat moss at 50% significantly increased total chlorophyll content in banana plants. Furthermore, N, P and K plant analysis has shown that vermicompost at 75% with peat moss gave the highest mineral content values at the two periods. Addition of vermicompost to the culture media improved in vitro-produced banana plants in greenhouse.

Thidiazuron-induced direct organogenesis from immature inflorescence of three date palm cultivars.

BACKGROUND: Inflorescence explants of date palm proved to be a promising tool for micropropagation of elite cultivars or rare males and females as organogenesis and somatic embryogenesis could be achieved. These plant materials are abundantly available every year and can be used as cheap and potent explants. Nevertheless, many difficulties could be faced in this protocol according to selection of the spathe size and age, media components, growth regulators, etc. The aim of this study was to determine the influence of various cytokinins on direct organs induction of three date palm cultivars (Selmi, Barhee, and Medjool) from immature inflorescence. An additional objective of this study was to investigate the effect of cytokinins and auxins on growth and development of Medjool cultivar. RESULTS: Various combinations of cytokinins were investigated on three date palm inflorescences as N6-(2-isopentenyl) adenine (2iP), kinetin, benzyleadenine (BA), and thidiazuron (N-phenyl-N'-1,2,3-thidiazol-5-yl urea) (TDZ). TDZ alone or in combination with BA proved to be superior for direct organogenesis in all three cultivars so that another combination of TDZ with BA was conducted. Results showed that moderate concentration of BA, with TDZ, gave superior response. Medjool cultivar response surpassed other two cultivars that made the possibility to conduct some growth regulators treatments on its multiplication and regeneration. TDZ at 0.5 + BA at 1.0 mg/l without activated charcoal seemed to enhance multiplication rate. Medium containing 0.5 mg/l of both naphthaleneacetic acid and indole butyric acid in addition to 1.0 mg/l indole acetic acid appeared to be more suitable for rooting stage of Medjool shootlets. CONCLUSION: In this study, we created an innovation sequence of growth regulators included in nutrient media for date palm direct organogenesis from inflorescence. Organogenesis has been accelerated from immature inflorescence explants and developed to healthy plantlets which acclimatized in greenhouse.

Innervation of the pelvic limb of the adult ostrich (Struthio camelus).

The pelvic limb of the ostrich is innervated by the lumbar and sacral plexuses. The lumbar plexus gave rise to several nerves (N.s) including, N. coxalis cranialis, lateral and cranial femoral cutaneous N.s, N. femoralis, cranial, caudal and medial crural cutaneous N.s, and N. obturatorius. The remaining nerves emanated from the sacral plexus. The N. iliotibial, N. ischiofemoralis, N. iliofibularis, and N. coxae caudalis were distributed in the thigh, while the N. ischiadica, which terminated as the tibial and fibular N.s that innervated the leg and foot. The tibial N. gave rise to the parafibular N. then divided to form the Nn. suralis medialis and lateralis. The N. suralis medialis continued as the N. metatarsalis plantaris medialis. The parafibular N. continued as the N. plantaris lateralis, which terminated as the R. digitalis of the fourth digit. The fibular N. terminated as the superficial and deep fibular N.s. The superficial fibular N. continued as the N. metatarsalis dorsalis lateralis and divided into two digital N.s to the third and fourth digits. The deep fibular N. crossed the ankle joint and continued as the N. metatarsalis dorsalis medialis that continued as the R. digitalis of the third digit. In general, the innervation of the pelvic limb of the ostrich was similar to the pelvic limbs of several different species of domesticated birds, including the chicken. We discuss the few differences as well as appropriate sites to perform nerve blocks for the lateral and medial dorsal and the lateral plantar N.s.

The arterial supply of the pelvic limb of the adult ostrich (Struthio camelus).

Blood to the pelvic limb of the ostrich is provided by the external iliac and ischiatic arteries that arise from the descending aorta. The external iliac artery (a.) gave rise to the pubic a. that supplied the obturator muscles and continued as the femoral a. The femoral a. gave off three branches: (1) cranial coxal a. to muscles above the pre-acetabular ilium; (2) cranial femoral a. to muscles cranial to the femur, the gastrocnemius muscle, hip and stifle joints and (3) medial femoral a. to muscles caudal and medial to the femur. The ischiatic a. gave rise to the caudal coxal a. that supplied muscles caudal to the femur, muscular branches to the iliotibialis lateralis muscle and to the deep femoral a. that supplied the iliofibularis muscle, cutanea femoralis caudalis and lateralis aa., and branches to the flexors of the leg and knee joint, then terminated as the sural and popliteal arteries. The sural a. supplied most of the flexors of the foot. The popliteal a. supplied the knee joint and flexors of the leg, and then terminated as the cranial and caudal tibial arteries. The caudal tibial a. supplied flexors of the foot. The cranial tibial a. provided four branches to the knee and ankle joints and to the leg. The cranial tibial a. continued into the foot as the common dorsal metatarsal a., which gave off seven different branches to the ankle and foot. With few exceptions, the arteries of the ostrich pelvic limb are similar to those of domestic fowl.
