Growth and Fatty Acid Composition of Borage (Borago officinalis L.) Leaves and Seeds Cultivated in Saline Medium
Journal of Plant Growth Regulation - Tập 32 - Trang 200-207 - 2012
The effects of salinity on growth and fatty acid composition of borage (Borago officinalis L.) leaves and seeds grown in hydroponic medium were investigated. Three different levels of NaCl (25, 50, and 75 mM) were applied. The first results showed that salinity significantly reduced plant growth by 56.5 % at 75 mM compared with the control, suppressed seed yield at 50 and 75 mM, and increased lipi...... hiện toàn bộ
Factors Affecting Somatic Embryogenesis Induction and Conversion in “Paradise Tree” (Melia azedarach L.)
Journal of Plant Growth Regulation - Tập 26 - Trang 268-277 - 2007
Factors affecting somatic embryogenesis induction and conversion in paradise tree (Melia azedarach) were evaluated. Somatic embryogenesis was influenced by plant growth regulators, explant stage, carbohydrate source and concentration, gelling agents, light, and induction times. MS medium with 4.54 μM thidiazuron (TDZ) was optimal for the induction of embryogenic tissue. Zygotic embryos that were 1...... hiện toàn bộ

Rapid quantitative analysis of a gibberellin-sterol inhibitor using high-performance liquid chromatographic cartridge columns
Journal of Plant Growth Regulation - - 1990
A rapid, sensitive, and economical chemical analysis of the triazole, gibberellin-inhibitor, paclobutrazol (PP333, [(2RS,3RS)-1-(4-chlorophenyl)-4,4-dimethyl-2-(1,2,4 triazol-1-yl) pentan-3-ol]) was sought, featuring high-performance liquid chromatography (HPLC) as the final quantitation step. Three C18-reverse phase columns (conventional, 250×4.6 mm; cartridge type, 125×4.6 mm; and minicolumn, 33...... hiện toàn bộ
Purification and partial characterization of a gibberellin 2β-hydroxylase fromPhaseolus vulgaris
Journal of Plant Growth Regulation - Tập 2 - Trang 251-264 - 1983
A gibberellin 2β-hydroxylase has been purified from mature seeds ofPhaseolus vulgaris. The enzyme is of molecular weight 36,000 and has the characteristics of a dioxygenase; the cofactors areα-ketoglu-tarate, Fe2+ and ascorbate, and activity is stimulated by catalase. The Vmax of the enzyme is 6.86 nmole h−1 mg−1, and the Km values for [1,2-3H2]GA1 andα-ketoglutarate are 0.085 μM and 21 μM, respec...... hiện toàn bộ
Effects of abscisic acid (ABA) and ABA analogs on freezing tolerance, low-temperature growth, and flowering in rapeseed
Journal of Plant Growth Regulation - Tập 13 - Trang 235-241 - 1994
Brassica napus and B. campestris are grown in Western Canada in areas subject to unseasonable frosts. At the seedling stage, cultivars of Brassica are very sensitive to frosts of -2° to-5°C, which are either lethal or delay the development of the plant. Seedlings of B. napus and B. campestris, germinated and grown at 10°C (16-h photoperiod), were treated with a foliar spra...... hiện toàn bộ
Senescence Networking: WRKY18 is an Upstream Regulator, a Downstream Target Gene, and a Protein Interaction Partner of WRKY53
Journal of Plant Growth Regulation - Tập 33 - Trang 106-118 - 2013
Transcriptional reprogramming is a central feature of senescence regulation, implying an essential role for transcription factors. A regulatory function has already been attributed to different members of the plant-specific NAC and WRKY families in Arabidopsis but also in other plant species. WRKY53 is one important senescence regulator of the Arabidopsis WRKY family that is tightly regulated on d...... hiện toàn bộ
Synthesis and Biological Activity of Urea and Thiourea Derivatives from 2-Aminoheterocyclic Compounds
Journal of Plant Growth Regulation - Tập 23 - Trang 280-291 - 2005
Thirty-eight N-substituted-N′-(2-thiazolyl and furfuryl)ureas and thioureas were prepared by reaction of 2-aminothiazole and 2-furfurylamine with the appropriate iso(thio)cyanate. All compounds were tested for herbicidal activity and selectivity on seedlings of wheat (a monocotyledonous plant) and cucumber (a dicotyledonous plant). Only one compound (1) out of 14 ureas was characterized by conside...... hiện toàn bộ
