Translocation of paclobutrazol, a gibberellin biosynthesis inhibitor, in apple seedlings.
The [(2RS,3RS)-1-(4-chlorophenyl)-4,4-dimethyl-2-(1,2,4-triazol-1- yl)-pentan-3-ol] (paclobutrazol, PP333) measured in apple seedlings (;York Imperial' Malus domestica Borkh) was confirmed by gas chromatography-mass spectrometry. Data showed that paclobutrazol was taken up through roots and transported primarily in the xylem through the stems and accumulated in leaves. No detectable basipetal m...
متن کاملEffect of paclobutrazol on water stress-induced abscisic Acid in apple seedling leaves.
Abscisic acid (ABA) was quantitated by enzyme-linked immunosorbent assay (ELISA) in water-stressed leaves from control apple seedlings, and also from apple seedlings treated for 28 days with paclobutrazol ([2RS, 3RS]-1-[4-chlorophenyl]-4,4-dimethyl-2-[1,2,4-triazol-1-yl] pentan-3-ol). The ELISA quantitative estimates were also validated by gas chromatography-electron capture detector and lettuc...
متن کاملCompetitive status influences tree-growth responses to elevated CO
1. Competition effects on growth of individual trees were examined for 4 years in aggrading, mixed-clone stands of trembling aspen ( Populus tremuloides Michx.) at the Aspen-FACE free-air CO 2 and O 3 enrichment facility in northern Wisconsin, USA. During each growing season stands received one of four combinations of atmospheric [CO 2 ] (ambient vs ∼ 56 Pa) and [O 3 ] (ambient vs ∼ 1·5 × ambie...
متن کاملEvapotranspiration changes of reference Crop during the growth stages of apple tree in Urmia and Semirom cities
The evapotranspiration of the reference Crop is of particular importance due to the changes in climate parameters of temperature, sunlight, humidity and wind speed in combination. the purpose of this study is to investigate the effects of climate change on evapotranspiration of apple during the growing season.For this purpose, the ECMWF database has been used for observation data of Semirom ...
متن کاملInfluence of Paclobutrazol on Growth and Flowering of Rhododendron ‘Sir
Shoot extension of Rhododendron ‘Sir Robert Peel’ was reduced, but flowering was more precocious after treatment of plants with paclobutrazol. All of the drench rates tested (0.05 to 0.4 g a.i./pot) proved excessive and resulted in prolonged shoot growth reduction but greatly increased the number of flowers. However, flowers produced at the higher drench rates were grossly malformed and unaccep...
