Wheat is the cereal most susceptible to lodging, particularly during flowering period and at early ripening stage. The use of plant growth retardants (PGRs) especially recommended when intensive nitrogen (N) fertilisation applied, which increases susceptibility plants lodging. This paper presents results tests into effects PGRs (PGR0—control; PGR1—chlormequat chloride (CCC) + trinexapac-ethyl (...

The effect of different types of plant growth retardants on fungal gibberellin (GA) formation has been studied in cultures of Gibberella fujikuroi and Sphaceloma manihoticola. Quaternary ammonium compounds (chlormequat chloride, mepiquat chloride, Amo-1618), triazoles (uniconazole and several experimental compounds), and the norbornanodiazetine tetcyclacis inhibited GA biosynthesis in both fung...

to evaluate the growth regulatory effect of chlormequat chloride (ccc) under drought stress conditions on three barley cultivars, a field study was conducted under badjgah agro climatic conditions (altitude 1810 m, longitude 52° 46´, and latitude 29° 50´) during 2003-2004 growing season. a randomized complete block based split- split plot of four replications was employed with two moisture leve...
