The effects of grapevines cutting soaking in Asahi SL on their rooting and further
plant development under optimal (20°C; 42% H2O v/v), drought (20°C; 18, 25,
32% v/v) or temperature (10°C, 30°C; 42% v/v) stress conditions were investigated.
Drought or temperature stress negatively affected subsequent development of
grapevine plants in optimal conditions during the first growth season as well as in
the year following winter storage. The influence of 10°C was the most unfavorable
one among all the examined stress conditions. The growth of plants obtained from
the rooted cuttings subjected to this temperature at the time when one developed
primary root appeared was inhibited. Asahi SL application in 0.2% increased
grapevine tolerance to temperature and drought stress. The positive reaction of this
chemical was more prominent when cuttings with one developed primary root were
exposed to the most severe drought stress (20°C, 18% H2O v/v). This chemical
agent decreased frost damages not only during winter storage but also positively
affected further growth in the next vegetation season.
