Flowering is the first of several events that lay foundation for mango production every year. The temperatures below 15°C readily promote floral induction. Decrease in temperature 20 0C common sub-tropical regions but seldom occurs many tropical ones. So, an alternative strategy optimum flower initiation under condition essentially required increasing productivity plant. Among different strateg...

Table 1. Effect of paclobutrazol (paclo) on plant height and number of leaves developed on hollyhock at 2, 4, or 6 weeks after treatment. All application techniques were designed to deliver 0.10 mg paclo/10-cm Our objective was to determine the efficacy of a given dosage of β-[(4-chlorophenyl)methyl]-α-(1,1-dimethylethyl)-1H1,2,4-triazole-1-ethanol [paclobutrazol (paclo)] applied using differin...

Fruit-set in tomato (Solanum lycopersicum) depends on gibberellins and auxins (GAs). Here, we show, using the cv MicroTom, that application of N-1-naphthylphthalamic acid (NPA; an inhibitor of auxin transport) to unpollinated ovaries induced parthenocarpic fruit-set, associated with an increase of indole-3-acetic acid (IAA) content, and that this effect was negated by paclobutrazol (an inhibito...
