For olive genetic improvement work it is very important to obtain a high rate of seed germination and a shortening of the juvenile period of the plants raised. By in vitro embryo culture, a 100% of germination is attained in a few days and the supply of adequate nutritive solutions and photoperiod speeds up seedling development during hardening, thus shortening juvenility. Mycorrhizal is anothe...

Reducing hippocampal neurogenesis sometimes, but not always, disrupts hippocampus-dependent learning and memory. Here, we tested whether animal age, which regulates rate of hippocampal neurogenesis, is a factor that influences whether deficits in spatial learning are observed after reduction of neurogenesis. We found that suppressing the generation of new hippocampal neurons via treatment with ...

Abstract The use of rootstocks provides choices to growers increase fruit quality and yield, obtain high-density planting, avoid juvenility, control tree size. choice rootstock for a citrus orchard was an important consideration. aim the study evaluate effects on leaf mineral composition physiology commercial cultivars (‘ Pontianak ’ tangerine, ‘ Pamindo pamelo Montaji lemon). For this purpose,...

Techniques of clonal selection, establishment of hedged stool-beds, and cutting propagation have been developed for Cunninghamia lanceolata (Lamb.) Hook. (Chinese fir) in Zhejiang Province, China, and clonal forestry has been implemented in a local programme based at Kaihua County Forest Farm. Cutting propagation and the maintenance of juvenility, and plantation performance of 102 clones in sin...

Microspore embryogenesis is a method of achieving complete homozygosity from plants. It is particularly useful for woody species, like Citrus, characterized by long juvenility, a high degree of heterozygosity and often self-incompatibility. Anther culture is currently the method of choice for microspore embryogenesis in many crops. However, isolated microspore culture is a better way to investi...

cyphomandra betacea (cav.) is a native species from south america that is cultivated because its fruits have a high content of vitamins. in colombia, it is common to find periods of drought between the rainy seasons or during enso events such as el niño. an adequate nutritional status of k+ in plants helps to increase the chance of tolerating the negative effects of drought stress. regarding th...

the overall goal of this review is to discuss the potential efficacy of herbal treatments. plants are considered among the main sources of biologically active chemicals. plant based drugs usage in our past decay became very renowned due to their fewer side effects and being less expensive than chemical ones. recently, more abrupt tendency in this field has been increased. furthermore, advances ...
