Abstract: Atliktų tyrimų tikslas buvo nustatyti 2-chloretilfosfoninės rūgšties poveikį Actinidia kolomikta vyriško klono M3 ir veislės ‘Landė’ augalų augimui ir vystymuisi. Nustatyta, kad paveikus augalus šiuo augimo reguliatoriumi, jų vegetacijos periodas sutrumpėjo 9–15 dienų. Nupurkšti augalai pasižymėjo morfologiniais pakitimais. Paveikus augalus 0,2 % augimo reguliatoriaus tirpalu, ūglių ilgis vegetacijos pabaigoje buvo statistiškai patikimai mažesnis. Nupurkštiems 2-chloretilfosfoninės rūgšties tirpalu augalams buvo būdingas mažesnis žiedų ir uogų kiekis. Veikiant skirtingoms augimo reguliatoriaus koncentracijoms, kito ir uogų dydžio parametrai Effect of 2-chlorethylphosphonic acid application on the growth and development of Actinidia kolomikta (PDF Download Available).

Investigations were conducted to determine the effect of 2-chlorethylphosphonic acid (at 0.10 and 0.20%) on the growth and development of one-year-old shoots of A. kolomikta. In 1999, plants of different ages were used. In 2000, two-year-old plants propagated by softwood cuttings (male clone M3 and cultivar Lande) and 2-year-old seedlings of clone F1 were chosen. 2-chloroethylphosphonic acid at 0.2% solution hindered the growth of shoots of seedlings and plants propagated by softwood cuttings. During the first 14 days after spraying, this effect was significant. Necrosis (clone M3) of buds and upper internodes of shoots, and leaf (Lande) fall were established. A part of shoots died. The morphological peculiarities varied considerably. At the end of the vegetation, the seedlings treated with 0.2% solution formed the greatest number of shoots. The period of vegetation of the plants affected by this growth regulator was shorter
