Abstract:	In this research we have examined the influence of deuterium low content water on Sequoia vitroplantlets, resulted from „in vitro” regeneration of this plant. The biological material was exposed to a 36-38°C (97-100°F) high environmental temperature, for 40 days. During this time we have made observations concerning plantlets growth and also their survival percentage. This experiment has shown that 50% to 75% proportion of deuterium low content water (DLCW), added in culture media, has a good stimulator effect to Sequoia sp. L vitroplantlets growth, and help vitroplantlets to pass thru a relative long warm period, protecting them from chlorosis induced by hyperthermia.
Keywords:	Sequoia, deuterium, water, culture media, heat resistance
