The role of ethylene and reducing agents on anther culture response of tetraploid potato (Solanum tuberosum L.)

Abstract: The role of ethylene in embryogenesis of cultured potato anthers was studied indirectly by testing various substances known to affect ethylene formation. The reducing agents ascorbic acid and L-cysteine prevented browning of anther cultures and significantly stimulated embryogenesis. Embryogenesis was also promoted by the use of the ethylene inhibitors AgNO3 and n-propyl-gallate and by the polyamines spermidine and putrescine. The use of the ethylene releasing compound ethrel significantly inhibited embryogene… Show more

“…In a study by Tiainen (1992) on anther cultures of the potato (Solanum tuberosum (L.)), reducing agents, ascorbic acid, and L-cysteine prevented browning of anther cultures and significantly stimulated embryogenesis. Embryogenesis was also promoted by the use of the ethylene inhibitor AgNO 3 , and by the polyamines spermidine and putrescine.…”

“…Pito by anther culture ('Pito dh.45/4' and 'Pito dh.119.1.1.') (Tiainen, 1992). The potato dihaploid lines and S. brevidens (CPC 2451) were cultured in vitro on MS20 (Murashige & Skoog, 1962;Jones et al, 1989) incorporating 100 mgl-1 casein hydrolysate.…”

“…In culture medium, PAs have been shown to increase the number of gynogenic embryos in Allium cepa L. (Martínez et al 2000), androgenic embryos in potato (Tiainen 1992), in some Indian wheat cultivars (Rajyalakshmi et al 1995), and in cucumber (Ashok Kumar et al 2004). However, rice culture lost regeneration capacity with increasing age (Bajaj and Rajam 1995).…”
