Spontaneous transition of the plasma confinement mode was observed in thehelical-axis heliotron device 'Heliotron J' for three different plasma heating schemes, ***-only. NBI-only.and the combination of ECH and NBI. The transition seems to occur above a certaincritical density. In addition to the confinement transition, a spontaneous shift of the hittingposition of the divertor plasma flux on the wall was observed. This shift could be related with thechange of the edge field topology.caused by.non-inductive toroidal currents.

The effects of ethephon and abscisic acid(ABA) application on ripening-related genes of pre-harvest ‘Kohi' kiwifruit(Actinidia chinensis) were studied to clarify.the possibility.of the fruit ripening on the vine. The fruits were treated on the vine at mature stage with 250 μL·L^(-1)ethephon or 100 μmol·L^(-1)ABA, and the expression levels of chlorophy.l sy.thase(Ac CLS), chlorophy.lase1(Ac CLH1), poly.alacturonase(Ac PG), expansin(Ac EXP),β-amy.ase(Acβ-AM), sucrose sy.thase(Ac SUSy., MADS-box SEPALLATA4/RIPENING INHIBITOR-like(Ac SEP4/RIN) and FRUITFUL-like(Ac TDR4/FUL) genes were analy.ed. The expression levels of Ac PG, Ac EXP, Acβ-AM, and Ac SUSy.increased in the ethephon-treated fruit, but those of Ac CLH1 at 6and 9 day. after treatment and Ac CLS decreased. Moreover, the expression levels of Ac SEP4/RIN and Ac TDR4/FUL, the latter of which is associated with ethy.ene biosy.thesis, were higher in the ethephon-treated fruit. The expression level of each gene in ABA-treated fruit was not significantly.different from that of the untreated control. The results suggest that ethephon application increases the expression levels of Ac PG,Ac EXP, Acβ-AM, Ac SUSy. Ac SEP4/RIN, and Ac TDR4/FUL in ‘Kohi' kiwifruit on the vine.
