14. In vitro callus induction and micropropagation of Thymus persicus (Lamiaceae), an endangered medicinal plant
Abstract This is the first attempt towards an efficient regeneration protocol for an endangered and valuable medicinal plant, Thymus persicus using in vitro callus induction and indirect organogenesis. Callus induction was performed on MS medium supplemented with different concentrations of NAA and 2,4-D, alone or in combination with BAP and KN. Maximum cal

15. Somatic embryogenesis in Acrocomia aculeata Jacq. (Lodd.) ex Mart using the thin cell layer technique
Considering the necessity of Acrocomia aculeata propagation for large-scale production, the aim of this study was to establish a somatic embryogenesis protocol using the thin cell layer (TCL) technique. Aerial parts of in vitro plants were transversally cut at the base into eight TCLs and placed in a culture medium for callus induction. The induction medium

16. Influence of Plant Growth Regulators on In Vitro Shoot Multiplication and Plantlet Formation in Cassia angustifolia Vahl
ABSTRACTAn effective and improved plant regeneration system was successfully developed using shoot tip explants taken from a two years old mature plant of Cassia angustifolia. The effect of different cytokinins, [6-benzyladenine (BA), Kinetin (Kin) and thidiazuron (TDZ)] at different concentrations (0.5-10 µM) were evaluated as augmented with Murashige and

17. Métodos para resgate, conservação e multiplação em larga escala de matrizes de Eucalyptus benthamii Maiden &Cambage / Methods for rescue, conservation and multiplication of matrices Eucalyptus benthamii Maiden &Cambege
The E. benthamii presents a great aptitude for cultivation in Brazil, especially in cold climates and with frequent frosts, this is due to your west of Sydney origin in Australia, where temperatures are very low, with frosts. Taking into account their optimal silvicultural performance, selected genotypes will certainly represent an excellent alternative for

18. Conjoint effect of oil-seed cakes and Pseudomonas fluorescens on the growth of chickpea in relation to the management of plant-parasitic nematodes
Soil application of organics has been explored as an alternative means of organic management of plant-parasitic nematodes. Efficiency of different oil-seed cakes of neem (Azadirachta indica), castor (Ricinus communis), groundnut (Arachis hypogaea), linseed (Linum usitatissimum), sunflower (Helianthus annuus) and soybean (Glycine max) were evaluated in field

19. Micropropagation of an elite F1 watermelon (Citrullus lanatus) hybrid from the shoot tip of field grown plants
The aim of this work was to develop a protocol for rapid micropropagation of an elite F1 hybrid watermelon cultivar using shoot tip of field-grown plants. Maximum frequency (73%) of shoot tip showed growth response in MS medium supplemented with 5 mg l-1 benzyl adenine (BA) and 0.1 mg l-1 indole-3 acetic acid (IAA). Upon transfer to cytokinin-enriched medium

20. In vitro multiplication of 'Flordaguard' rootstock: cytokinin source and concentration effects, explants orientation and period of permanence in the culture medium
This work aimed at studying the effects of different sources and cytokinin concentrations, as well as explants orientation and time of their permanence in shoots induction medium to obtain high multiplication rate. Four experiments were carried out to evaluate the sprout percentage mean, shoots number per explant, elongated shoots percentage and shoots lengt

22. Euschistus heros mass rearing technique for the multiplication of Telenomus podisi.
The objective of this work was to improve the mass rearing technique of Euschistus heros in laboratory. Nymphs and adults were reared at densities 100, 200, 300 and 400 eggs per Petri dish (9 cm diameter), and at 50, 100, 150 and 200 couples per rearing cages (900 mL), respectively. Survival rate of immature stages and survivorship and reproduction of adults
