14. Effect of picloram, additives and plant growth regulators on somatic embryogenesis of Phyla nodiflora (L.) Greene
The present study describes the plant regeneration via somatic embryogenesis in suspension culture derived from the leaf and stem explants of Phyla nodiflora. The medium type, plant growth regulators, complex extract (coconut milk and malt extract) and anti-oxidant (activated charcoal, ascorbic acid, Polyvinylpyrrolidone and citric acid) markedly influenced

15. Plant tissue culture and regeneration of transgenic plants from embryogenic callus and immature leaves of sugarcane / Cultura de tecidos e regeneração de plantas transgênicas a partir de calos embriogênicos e de folhas imaturas de cana-de-açúcar
Sugarcane is a polyploidy monocot and allogamous species that has low reproductive rate due to the difficulty of flowering. Because of these genetic and physiological characteristics breeding program takes long time and demand hard labor. Alternatively, modern biotechnology approaches contribute to the development of new cultivars. In this work we studied th

16. Pro-embryogenic cell viability and cell suspension of Byrsonima intermedia A. Juss. / Viabilidade de CÃlulas PrÃ- EmbriogÃnicas e SuspesÃo Celular de Murici-Pequeno
The Murici-pequeno (Byrsonima intermedia A. Juss) is a fruitful medicinal species of Cerrado which presents difficulties to be propagated by conventional methods. This fact makes necessary the development of alternative methodologies of propagation for this species. In this work it was studied the in vitro seedlings growth according to residual effects of se

17. Embriogênese somática a partir de folhas imaturas e flores desenvolvidas in vitro de dendezeiro (Elaeis guineensis Jacq) / Somatic embryogenesis from immature leaves and flowers developed in vitro from oil palm (Elaeis guineensis Jacq)
The study aimed to establish an efficient protocol for somatic embryogenesis of the oil palm, especially all of cultivars explored in Brazil, as well as to acomplish the anatomical caracterization of the embryogenic process. For induction of somatic embryogenesis we used two explants types, leaves segments and female inflorescences, resulting in two experime

18. InduÃÃo de mutaÃÃo em feijÃo-caupi [Vigna unguiculata (L.) Walp., cultivar BR-14 mulato, visando à obtenÃÃo de mutantes tolerantes à salinidade
Among cultivated bean varieties cowpea [Vigna unguiculata (L.) Walp.] stands out for its high protein content and its ability to grow under adverse conditions. As such, this species has become one of the most important subsistence crops for rural populations in Brazilian north-eastern region. However, aside from increasing environmental problems, soil salini

19. Indução da embriogênese somática em cana-de-açúcar / Induction of somatic embryogenesis in sugarcane
Sugarcane is one of species more cultivated in whole world, reaching more than 80 countries. With the biotechnological progresses, important tools appear for genetic breeding of cane. The production of transgenic plants is very important for clonal propagation species as sugarcane. But plant transformation is dependent of in vitro cultivation and, among thei

20. In vitro culture and somatic embryogenesis of zygotic embryos of macaúba (Acrocomia aculeata (Jacq). Loddiges) / Cultivo in vitro e embriogênese somática de embriões zigóticos de macaúba (Acrocomia aculeata (Jacq). Loddiges)
The objectives of this work were to propose the proceeds regarding the culture of embryos and induction of somatic embryogenesis of the Acrocomia aculeata palm tree using as explants source the mature and immature zygotic embryos. In the in vitro embryo culture the following were studied: a) the effect of the incubation conditions and of the activated charco

22. Production, morphologic and ultra-structural analyses of Passiflora spp. callus. / ObtenÃÃo, anÃlises morfolÃgicas e ultra-estruturais de calos de Passiflora spp.
Brazil occupies a position of prominence in the passion fruit plant culture, being the largest world producer of passion fruit. In the last years, the increasing demand resulted in a expansion of the planted area resulting in the expansion and appearance of many diseases. Some species not cultivated, as Passiflora gibertii N.

23. Embriogênese somática em macaúba: indução, regeneração e caracterização anatômica / Somatic embryogenesis in macauba: induction, regeneration and anatomical characterization
Among oleaginous plants that could be used to produce biodiesel, macauba (Acrocomia aculeata (Jacq.) Lodd. ex Martius) is known as a highly productive and semi-arid adapted palm. However, this species shows some problems regarding to its propagation and somatic embryogenesis can be an alternative. The aim was to contribute to the development of macauba somat

24. EmbriogÃnese somÃtica e isolamento de protoplastos de pequizeiro / Somatic embryogenesis and protoplast isolation of Caryocar brasiliense CAMB.
The Caryocar brasiliense is one of the native fruit species from Cerrado with higher economical, ecological and social importance. In the last decades, large land extensions in the â Cerrado â has been used for agricultural system. This fact associated with a natural low regeneration rate has caused the reduction in natural populations of the species. Base
