Aim. Preparation of aseptic seedlings Salvia hispanica L., callus initiation in vitro and establishment of primary explants suitable for the callus production. Methods. Seeds are sprouted on our own modification of conventional methods. The non-hormonal Murashige-Skoog agarized nutrient medium was used as basic medium for the experiments. Parts of one-month seedlings (roots, hypocotyl, cotyledon leaves) were used as explants for the use of the colza. We added growth regulators (BAP, 2,4-D) in different concentration combinations into the nutrient medium for callus initiation. Statistical processing was performed in Microsoft Office Excel. Results. Aseptic S. hispanica seedlings have been obtained. The callus growth was initiated on all types of explants, the dependence of the callus intensity on the type of explants and the growth regulators content in the nutrient medium was established. Morphogenic callus and root-regenerants have been obtained. Conclusions. Hypocotyl was the most suitable primary explant for callus growth. Seedlings, leaves and roots showed low morphogenetic capacity. The nutrient medium with an elevated 2,4-D content was the most effective for initiation of callus genesis and proliferation of non-morphogenous callus. A high concentration of 2,4-D in the medium improves S. hispanica callus growth but suppresses its morphogenic ability.Keywords: Salvia hispanica (Chia), in vitro culture, callus.

Shoot cultures of five apple cultivars, M.27, M.9, M.26, MM.111 and Macspur, a strain of McIntosh, were established in vitro and their response to different concentrations of cytokinin (benzyladenine, BA) and auxin (naphtheleneacetic acid, NAA) were measured. At the three BA concentrations tested (1.0, 5.0 and 10 μM) cultivars differed in the number of shoots produced and in their requirements for BA for optimum shoot production. M.27 produced the most shoots followed by Macspur, M.9 and M.26. The best concentration of BA for shoot production was 5.0 μM for Macspur and M.26 but slightly higher for M.27 and M.9. Rooting response was tested at NAA concentrations of 0.1, 0.33, 1.0, 3.3, 10 and 33 μM. The range of concentrations in which rootstock cultivars rooted was broader than for the scion cultivar Macspur and the percent rooting of rootstocks (about 85%) was higher than Macspur (58%). The most rooting occurred at 1.0 or 3.3 μM NAA. M.9 produced callus, which prevented rooting, when chronically exposed to NAA so a procedure of acute treatment was used. This allowed root initials to form but avoided callogenesis. Possible reasons for the different responses of the cultivars to cytokinin and auxin are discussed.

Strength Medium

A study was made of the influence of light, temp., growth regulators, and sugar and macrosalt concn. on the growth and morphogenesis of leaf and axis explants of young Shorea curtisii, S. obtusa and Dipterocarpus grandiflorus. Terminal and axillary buds grew best on half strength Murashige and Skoog medium. Leaf explants formed more callus on full strength medium, when containing part of the midrib and when taken from the lower half of the leaf. More than 95% of D. grandiflorus explants were infected by a fungus apparently present in the parent plant. (Abstract retrieved from CAB Abstracts by CABI’s permission)

Hancornia Speciosa

Hancornia speciosa is a fruit tree that is in the process of domestication. This time the propagation in vitro when well developed can promote conditions for the production of quality seedlings for this fruit. In vitro culture technologies are of great importance for conservation programs of genetic resources and genetic improvement of mangabeira. The objective of this study is to establish a methodology the micropropagation of Hancornia speciosa, Gomes, of three varieties (cuyabensis, gardneri and pubescens) by in vitro germination of seeds under different growth regulators. Fruits were collected at School of Agronomy of the Federal University of Goiás, transported to the Laboratory of Biotechnology, Federal Institute Campus Urutaí - Goiás, inoculated for germination in test tubes containing MS growth medium with 50% of salts concentrations, with five different concentrations of IBA. It was observed that the in vitro germination of cuyabensis, gardneri, and pubescens were 66.00 %, 64.05 % and 76 %, respectively. The beginning of germination occurred from three days for gardneri variety, six days for pubescens variety, and eigh day for cuyabensis variety, extending to the 16 days for gardneri variety, and 28 days for the other varieties. Explants of different varieties differ in their manifestations when cultured in vitro. The aseptic method was effective for the control of fungal agents
