Abstract
The growth responses of Actinidia chinensis raised from cuttings were compared in 8 h short days (SD) and 16 h long days (LD) at 15, 20 and 25 °C, as well as under varying day and night temperatures The data obtained reveal effects on stem elongation, apparent plastochrons, leaf area and shape, as well as dry matter accumulation and water contents of different plant parts These investigations were supplemented by studies on the effects of applied GA3 and ethephon Alternating day/night temperatures (thermoperiodicity) increased leaf area and d wt accumulation in LD Effects on sugar and starch contents, are described and discussed Unexpected effects such as very high petiole water contents and their continuous growth, increased twisting of the climbing stem in SD and other findings are also reported and discussed
