Studies with excised shoots of six gladiolus cultivars viz., Bellariana, Blue Moon, Cream White, Friendship, Her Majesty and Top Brass indicated that paclobutrazol enhanced early cormel initiation and development. The interaction between paclobutrazol and sucrose was significant for cormel size. Supplementation of 10 mg L paclobutrazol and 120 g L sucrose to Murashige and Skoog’s medium favored...

Late-season height control of poinsettia (Euphorbia pulcherrima) is difficult since most chemical growth retardants adversely reduce bract size when applied after first bract color. Paclobutrazol (Bonzi) controls stem elongation late in poinsettia crop development but can excessively reduce bract size if improperly applied. Two experiments were conducted to quantify how paclobutrazol applicatio...

Use of paclobutrazol is common strategy for inducing uniform and profuse flowering in mango. The possible mechanism by which paclobutrazol exert such responses are less understood. The present investigation was carried out to investigate possible role of polyamines and ethylene biosynthesis in the paclobutrazol induced floral induction in mango. Following paclobutrazol soil drenching applicatio...

A simple, accurate, and highly sensitive analytical method was developed for determining the paclobutrazol residue in potato and soil, the dynamics dissipation in soil. Extraction was carried out by low temperature partitioning and analyzed by ultrahigh performance liquid chromatography tandem mass spectrometry (UHPLC-MS/MS). For a favor extraction yield, the parameters such as temperature and ...

We examined the effects of nitrogen and phosphorus fertilizer and paclobutrazol on flowering precocity and abundance in Eucalyptus nitens Deane & Maid. Trials to test these effects consisted of a factorial nitrogen by phosphorus experiment replicated on two sites and factorial nitrogen by paclobutrazol experiments conducted separately on reproductively immature and reproductively mature trees. ...

The influence of the in vitro conditioning and rooting of the microcuttings in different basal media viz., Murashige and Skoog and Gamborg supplemented with various concen­ trations of paclobutrazol (0.25^1.0 mg/1) on their in vivo establishment and growth was in­ vestigated using four citrus species viz., C. reticulata Blanco (Khasi Mandarin), C. volkameriana Ten, and Pasq, C. reshni Tanaka (C...

The current study was carried out to evaluate the effect of some growth retardants such as alar, ethrel, cycocel and paclobutrazol with different concentrations (50, 100, 150 and 200 ppm.) on maize dwarf mosaic virus (MDMV) in vitro and in vivo. In vitro experiment, growth retardants reduced the occurrence of mosaic symptoms on maize plants. These percentages were reduced to 40%. Paclobutrazol ...

Eucalyptus nitens (Deane & Maiden) Maiden takes at least five years to initiate flower buds from seed and is an infrequent and light flowerer. Because this behavior constitutes a major impediment to breeding programs, we examined the mechanisms controlling floral induction in E. nitens, with the long-term aim of reducing generation time and increasing seed yield. Application of paclobutrazol re...

paclobutrazol was utilized to analyze its role in water stress amelioration and post drought recovery of container-grown pear ( pyrus communis cv. biroti ) saplings. following planting, paclobutrazol was applied as soil drench at concentration of 0, 0.15 and 0.3 mg per pot. three months following planting, saplings were subjected to three water stress treatments of: 0, -0.4 and -0.8 mpa. contro...

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...
