EFFECT OF GROWING MEDIA, TYPES OF FERTILIZATION AND THEIR INTERACTIONS ON GROWTH, FLOWERING, BULBS PRODUCTIVITY AND SOME CHEMICAL CONSTITUENTS OF IRIS TINGITANA CV. GOLDEN BEAUTY

This research was aimed to identify the influence of Atonic cencentration to the growth of single-node Vanilla cutting planted at various growing media types. Completely randomized design was used in this research with two factors namely Atonic concentration (500 ppm, 1000 ppm, 1500 ppm, 2000 ppm, dan 2500 ppm) and growing media types (tanah, pasir, tanah + pupuk kandang, tanah + pasir, tanah + pasir + pupuk kandang). The result showed that there were no interaction between Atonic concentration and growing media types to the growth of single-node vanilla cutting. Furthermore, the application of Atonic concentration at 2000 ppm established the best result of root length (12,32 cm) and root dry weight (0,16); while the best result of germination percentage (92,23%) revealed by Atonic concentration of 1500 ppm. Regression analysis of germination percentage showed that the optimal concentration of Atonic was 1842 ppm with R<sup>2</sup> = 60,3%. Mixed media of soil + sand + dung performed the best result in root length, root dry weight and germination percentage.

One-year-old liners of Firebird crape myrtle (Lagerstroemia indica L. 'Firebird') and Vicary golden privet (Ligustrum X vicaryi) were planted in 7.6 liter containers. The growing media consisted of 3 pinebark: 1 Canadian peat moss: 1 sand and 3 sawdust: 1 Canadian peat moss: 1 sand (v/v/v). Both media were amended with NH4NO3 and dolomite. Several controlled release fertilizers at varying rates were incorporated into each medium prior to planting. Thirty, 60 and 90 days after planting, leachate samples were collected and tested for E.C. and pH. Fertilizer Sierra (17-6-10) and Osmocote (18-7-13) resulted in maximum shoot dry weight with both species and media types followed by Osmocote (24-4-8) and Escote (20-4-11). Plants grew equally well in pinebark and sawdust medium. After 30 and 60 days leachate from Sierra (17-6-10) had highest E.C. levels. Osmocote (18-7-13 and 24-4-8) recorded highest E.C. at 90 day sampling date. The sawdust medium had higher pH values than the pinebark.

Npk Fertilizer

Abstract A pot experiments was carried out to evaluate the influence of growing media and combined treatments of NPK with either benzyladenine or gibberellic acid on growth, chemical constituents and anatomical structure of Dracaena marginata ‘Bicolor’. The plants were grown in two growing media; peat-moss, peat-moss+ sand (1:1, v v-1), received monthly NPK fertilizers (2 and 4 g pot-1) combined with either of benzyl adenine (BA) at 100 and 150 ppm or gibberellic acid (GA3) at 150 and 250 ppm, while the control plants received no treatments. As general, the results indicated that, peat- moss was superior to peat-moss+ sand medium on increasing most of vegetative growth parameters in terms of plant height, number of leaves/plant, leaf area, root length, as well as fresh and dry weights of leaves, stems and roots/plant, besides some macro elements represented in N, P, K, Ca and Mg% in both leaves and stems. While plants grown in peat-moss+ sand possessed significantly higher contents of total chlorophylls, total carbohydrates, Cu, Fe, Mn, Zn and B than those grown in peat- moss alone. Plants received combined NPK with either BA or GA3 resulted in significant increases in most of morphological and chemicals content over the control plants and it was outstanding that, GA3 was more effective than BA when they were combined with NPK. It can be concluded that for the highest quality, quantity growth and economic production of Dracaena marginata ‘Bicolor’, the plants could be grown in a medium of peat-moss and supplied monthly with NPK fertilizer at 2 g plant-1 along with foliar sprayed with 250 ppm GA3.

Ultrathin Frozen Sections

The mammary gland ultrastructure in various functional states is the object of our investigations. The material prepared for electron microscopic examination by the conventional chemical methods has several limitations, the most important are the protein denaturation processes and the loss of large amounts of chemical constituents from the cells. In relevance to this,one can't be sure about a degree the observed images are adequate to the realy ultrastructure of a living cell. To avoid the disadvantages of the chemical preparation methods,some autors worked out alternative physical methods based on tissue freezing / freeze-drying, freeze-substitution, freeze-eatching techniqs/; actually the technique of cryoultraraicrotomy,i,e.cutting ultrathin sections from deep frozen specimens is assented as a complete alternative method. According to the limitations of the routine plastic embbeding methods we were interested to analize the mammary gland ultrastructure during lactation by the cryoultramicrotomy method.

Analysis of the constituents of renal and biliary calculi may be of help in the management of patients with calculous disease. Several methods of analysis are available for identifying these constituents. Most common are chemical methods, optical crystallography, x-ray diffraction, and infrared spectroscopy. The application of a SEM with x-ray analysis capabilities should be considered as an additional alternative.A scanning electron microscope equipped with an x-ray “mapping” attachment offers an additional dimension in its ability to locate elemental constituents geographically, and thus, provide a clue in determination of possible metabolic etiology in calculus formation. The ability of this method to give an undisturbed view of adjacent layers of elements in their natural state is of advantage in determining the sequence of formation of subsequent layers of chemical constituents.
