“…The high mortality of in vitro plants when transplanted to soil may be attributed to an excess of water loss because of a deficient stomatal function (Brainerd et al 1981;ziv et al 1987;Marín et al 1988;Sutter 1988) and/or to high cuticular transpiration (Preece & Sutter 1991), fundamentally caused by defective deposition of epicuticular waxes (Sutter & langhans 1982;Wardle et al 1983), as well as the appearance of abnormal stomata (Hazarika 2006).…”

“…Da mesma forma ZIV et al (1987) aumentaram a proporção de plantas normais em cultura de crisântemo reduzindo os níveis de nitrato de amônio ou eliminando-o completamente do meio MS. Uma tendência inversa com os tratamentos de cálcio está evidenciado na Tabela 3 onde a dose máxima de 15,0 mM eliminou parcialmente a vitrificação, enquanto a total ausência de CaCl 2 elevou este índice para 50%. Há também a possibilidade de se reduzir a vitrificação aumentando os níveis de cálcio no meio (ZIV, 1991).…”

“…Plantas vitrificadas são caracterizadas por apresentarem baixos níveis de lignina e celulose ; baixa resistência de parede celular (KEVERS & GASPAR, 1986); hipertrofia celular (VIEITEZ et al., 1985); folhas entumescidas e quebradiças (DEBERGH, 1983;LESEHEM et al, 1988a,b;ZIV et al, 1987) e reduzida taxa de sobrevivência em condições autotróficas (SUTTER & LANGHANS, 1979).…”

“…La cuticule des feuilles des vitroplants est très fme, très perméable à l'eau (Conner et Conner, 1984 ;Sutter et Langhans, 1979) et les stomates restent toujours en position ouverte (Ziv et al, 1987 ;.…”

“…Lorsqu'ils sont transférés du bocal dans une serre d'acclimatation où l'humidité relative de l'air est beaucoup plus faible, ils sont très sensibles à la déshydratation et leur survie dans ces conditions est parfois aléatoire. En effet, un grand nombre d'espèces cultivés in vitro n'ont pas de régulation stomatique (Brainerd et Fuchigami, 1982 ;Conner et Conner, 1984;Ziv et al, 1987;Popisilova et al, 1988). Leurs stomates restent toujours ouverts pendant la photopériode et la nyctipériode, même en présence d'acide abscissique, de faibles pressions partielles de C0 2 ou d'une déshydratation partielle (Brainerd et Fuchigami, 1982).…”
