The shoot apices of ten groundnut interspecific hybrids, showing peanut stripe virus symptoms were used as explants. Murashige and Skoog (MS) medium containing 1 mg dm-3 each of naphthaleneacetic acid (NAA) and benzylaminopurine (BAP) supported maximum callusing of the hybrids J 11 × Arachis sp. PI 30008 as well as J 11 × A. sp. Manfredi # 5 (86.3 ...

Field experiments were conducted with sesame (Sesamum indicum L. cv. Rama) for two years (1997 and 1998) to study the effect of three level of irrigation (F+C, B+C, B+F+C) and two growth regulators (CCC, 200 ppm CCC; 100 ppm and BX-112, 100 ppm; BX-112, 50 ppm) on growth (root and shoot length, average number of primary branches/plant), morpho-phys...

A successful in vitro propagation system for the semi-dwarfing cherry rootstock Maxma-14 (Prunus avium L.) has been developed. Shoot tips and axillary buds were successfully established in vitro. Multiplication rate of about 6 was achieved over a 4-week period using Murashige and Skoog medium with 4.44 μM benzyladenine and 0.49 μM indole-3-butyric ...
We used axillary buds as initial explants for hormone interaction studies required for in vitro cultivation of S. allagophylla. Callus production was achieved on gelled Murashige & Skoog medium (MS) supplemented with indole-3-acetic acid (IAA= 0.1 and 0.5 mg.l1 alone or combined with 6 benzylaminopurine) (BA= 0.01 and 0.1 mg.l-1). A hormone balanc...
Different growth regulators combinations were tested on the production of anther callus in tomato cultivar IPA 5. Calli were induced on media supplemented with 1.0mgL-1 gibberellic acid (GA3), 0.05mgL-1 alpha-naphthaleneacetic acid (NAA) plus 0.1mgL-1 6-benzylaminopurine (BAP), or with 1.0mgL-1 BAP plus 1.0mgL-1 NAA. The medium containing 1.0mgL-1 ...

Hypothesizing that seed abortion in stenospermocarpic grapes (Vitis vinifera L.) is caused by high gibberellin levels in the seed during the first stages of its development, we studied the effect of gibberellic acid GA3 and uniconazol (a GAs biosynthesis inhibitor) on this phenomenon. In vitro germination was analyzed in the seedless cultivars Empe...

Interactions of growth regulators and polyethylene glycol on maturation of geranium somatic embryos were investigated. Somatic embryos were induced on medium with 20 μM thidiazuron for 3 days. The growth regulators used were 1 µM abscisic acid, jasmonic acid, napthaleneacetic acid and benzylaminopurine at 21 days from the start of induction. Benzyl...
The aim of this thesis is to analyze the seed and ware potato production systems in Argentina and their possible yield constraints in order to develop specific strategies to increase seed quality and tuber yield.This thesis starts with a survey of the actual potato production systems in Argentina carried out during 1994/95 and updated in 1999. Arge...

A reverse of the delaying effect of gibberellic acid (GA3) was observed in in vitro tuberization of potato plantlets when the medium contained 0.8×10−5 M jasmonic acid (JA). The promoting effect of JA seemed to be correlated with the initial absence of growing roots, probably through direct activity of JA in microtuber-producing buds in the stoloni...
