Production of marigold can be improved to a large extent by the judicious cultural operations i.e. application of optimum fertilizer at required time, crop management practices and use of plant growth regulators. Hence, an experiment was carried out in the Research Farm of Adhiparasakthi Horticultural College, Kalavai, during 2018-19 to find out the effect of plant growth regulators (NAA, GA3) and growth retardants (Maleic hydrazide, Alar) on growth and yield of African marigold var. Pusa Narangi Gainda.

GA3 is a natural growth hormone and is a part of a type of plant hormone called gibberellins. GA3 promote cell division and a number of plant development mechanism and encourages numerous desirable effects such as plant height, uniform flowering, reduced time to flowering and increased flower number and size. GA3 200 ppm enhanced vegetative growth and flowering.

A field trail was conducted to study the effect of different levels of growth promoters and retardants on growth and flower yield of different cultivars of African marigold. Two PGR’s namely Gibberellins (GA3) and Cycocel (CCC) were taken as growth promoter and growth retardant, respectively. Two cultivars namely Pusa Narangi Gainda and Pusa Basanti Gainda were taken to evaluate their suitability in Chhattisgarh. The result indicated that the growth and flower yield were significantly influenced by different plant growth regulators and cultivars.

Hydrangea (Hortensia) is a highly popular ornamental plant for garden decoration, and now it is commercially produced for cut flower branches. The aim of this study was to set up a protocol for large scale for in vitro propagation of Hydrangea macrophylla, for this purpose two type of explant (shoot tip and node) were sterilized and the best percentage of survival explants (40%) was obtained when explants immersed for 20 min in 1.0 or 1.5 % NaOCl. For in vitro multiplication, Murashige and Skoog medium supplemented with 1.0 mg/l BA and 2.0 mg/l Kin was the best treatment on shoot number.
