Pummelo (Citrus maxima Merill) Seedlings Growth as Influenced by Plant Growth Regulators and Macronutrients

Growth and Yield of Summer Tomato as Influenced by Plant Growth Regulators

A field experiment was carried out at Horticulture Farm of Sher-e-Bangla Agricultural University, Dhaka-1207, Bangladesh, to assess the effect of different plant growth regulators on tomato during summer season 2011. Different plant growth regulators (PGR) viz. PGR = Control, PGR = 4-CPA (4-chloro phenoxy 0 1 acetic acid) @ 20 ppm, PGR = GA (Gibberellic Acid) @ 20 ppm and PGR = 4-CPA + GA3 @ 20...

Sunflower morphology and yield as affected by foliar applications of plant growth regulators

Plant height of sunflower is a major agronomic trait affecting crop performance in the field and its adaptation to mechanical harvest. Field experiments were conducted to study the effect of foliar application of paclobutrazol (PBZ) at 12.5 g ai/ha, mepiquat chloride (MPC) at 25.0 g ai/ha and chlormequat chloride (CCC) at 1,500 g ai/ha in single or double applications on sunflower plant mor...

Response of Germination and Seedling Growth of Pepper cultivars to Seed Priming by Plant Growth Regulators

In order to study the germination and growth of pepper seeds, a factorial experiment based on a completely randomized design with three replications was conducted. The first factor was consisting of five cultivars of pepper (Marquiza, Cadia, California Wonder, California Wonder 310 and California Wonder 300) and the second factor was gibberellic acid with three levels (0 as control, 250 and 500...

Plant Growth Regulators

Plant growth regulators are hormone-like chemicals that occur naturally in plants, and play a central role in their growth and development. Five major classes of plant growth regulators have been identified as plant hormones, but scientists believe that there are more waiting to be discovered. The five growth hormones include auxins, gibberellins, cytokinins, abscisic acid, and ethylene. Collec...
