“…Propagation of Narcissus by twin scales or chipping is well established (Hanks andRees 1978, 1979;Tompsett 1981Tompsett -1982Flint 1983Flint -1984Hanks 1985;Squires and Langton 1990). This technique of dissecting bulbs into small bulb scale sections subtended by the basal plate and putatively containing an axillary bud has not been assessed for garlic, although it has been used for Allium cepa (Hussey and,Falavigna 1980;Kahane et al 1992).…”

Explants comprised a small (1-3 mrn) piece of basal plate, an axillary bud and one or two subtending bulb scales' A medium containing MS salts and 0.1 mg L-r 1O.S pU) NAA and 2.0 mg L-r (8.8 pM) BAP or 2iP promoted axillary shoot multiplication., Bul6 formation of garlic ihoot cultures was obtained on a medium containing a lower concentration of macro-and minor elemenrs. The substitution of glucose and manitol for sucrose resulted in a bulbing medium with higher carbohydrate levels than the multiplication medium. Genotypic differences for both shoot multiplication and bulb formation in vitro were observed. The mean number of shoots produced were: Chets (9.5), #72 (8.0), Elephant (7.2), Shaw (7.1) and Block (6.1 Garlic cloves were dissected to produce twin scale sec-

“…Larger scales produce more bulblets of greater weight than smaller ones (Matsuo et al, 1987;Matsuo and Van Tuyl, 1986). In Narcissus, the number and size of differentiated bulblets are infl uenced by the relative position of starting scales in the bulb using the twin-scale technique (Hanks, 1985).…”

External, middle and inner scales in parent bulbs were studied to evaluate bulblet differentiation in Lilium longiflorum Thunb. during scale propagation at 25 °C. A 13-stage developmental process describes different steps including preprimordial, primordial, and bulblet formation. For all scales, preprimordial and primordial stages occurred within the first 4 days. The differentiation process depended on parent scale position. Most bulblets arising from external scales developed three true scales after 30 days while bulblets from middle scales formed four true scales. Homogeneity in the morphology of the parent scales, only shown in the middle ones, was associated with a rapid change in developmental stage for the population of bulblets. Inner scales showed few bulblets with three and four true scales, the rest remaining at earlier developmental stages. Bulblet production decreased from external to internal scales: 2.6, 2.2, and 1.2 bulblets per scale, respectively, and showed a positive correlation with the scale base width. Maximum scale weight and surface area and maximum bulblet fresh and dry weight occurred in the middle scales. We conclude that middle scales are the ideal starting material for experimental uses involving scaling propagation. For production purposes, the external scales, in addition to the middle scales, must also be included for propagation.

“…horticultural practice. Propagation by chipping is used commercially with Eucomis [9], Galanthus [10] Hippeastrum and Lilium [11], Narcissus [12]. The scoring method is applicable, inter alia, for Hyacinthus, Scilla, Fritillaria [13], Hymenocallis [14], and Ornithogalum [15].…”

The genus Lachenalia (Asparagaceae) represents spectacular and botanically diverse ornamental, bulbous species originating from Southern Africa. The main aim of this study was to determine, for the first time, the possibility of propagation of lachenalia cultivars ('Namakwa' , 'Rainbow Bells' , 'Rupert') by two in vivo techniques: chipping and scoring, which can be applied in procedures of bulb production. In the second part of the experiment, the plant growth and the quality of bulblets after the first season of cultivation in a greenhouse were estimated. The survival ability of bulb-scale segments and scored bulbs of the tested cultivars ranged from 62% to 95%. Chipping method generated eight bulblets per mother bulb with an average weight and diameter of 0.17 g and 0.29 cm, respectively, while scoring two/three bulblets per mother bulb with an average weight and diameter of 0.28 g and 0.5 cm, respectively. In the first season of cultivation, bulblets obtained by chipping produced longer leaves than those obtained by scoring technique. Only bulblets of 'Rupert' obtained by scoring showed the capacity to flower ('Namakwa' and 'Rainbow Bells' remained in a juvenile phase). When assessing the bulb yield after the first season of cultivation, it was found that irrespective of cultivar, bulbs obtained by chipping achieved twice the weight coefficient of those obtained by scoring.
