African marigold, being tall enough and producing large flowers suitable for preparing garlands, is the most cultivated cultivar of marigold in Nepal. Besides, pinching other improved cultural techniques, a number chemicals, hormones phyto-hormones are tested found to impart varying response marigold. This review has its importance standardizing type concentration plant growth regulators Online...

Early cone formation is a consistent issue in Fraser fir Christmas tree plantations the eastern United States. Growers must remove cones by hand, resulting significant labor costs, as degrade aesthetic value of trees. In this study, we conducted two series experiments collaboration with several farms to determine effectiveness applying plant growth regulators (PGRs), specifically GA-inhibitors,...

ABSTRACT- Growth retardants are natural or synthetic chemical substances which are directly applied to crops to alter some structural processes. It is expected that these alterations modify hormonal balance and growth leading to increased yield, improved crop quality or facilitated harvesting. Cycocel (CCC) or chlormequat chloride (2-chloro ethyl trimethyl ammonium chloride) as a synthetic grow...

Rapid growth and scattered plant types are urgent issues for potted Melaleuca alternifolia. An effective strategy dwarfing cultivation is the exogenous application of regulators (PGRs) to plants. However, many non-wood forest species, there currently limited understanding regulatory mechanism effects PGRs, which greatly limits PGRs. In this study, three paclobutrazol (PP333), uniconazole (S3307...

Plant growth regulators (PGRs) are commonly used in commercial farming to control lodging in cereals. PGRs have been shown to alter yield formation and plant stand structure, other than the straw length. To study their potential in Northern growing conditions PGRs and their application time impacts on plant stand structure and yield formation in tall and short statured cultivars of barley, oat,...

Chemical plant growth regulators (PGRs) are used in the production of ornamental potted and bedding plants. Growth control is needed for maximizing production per unit area, reducing transportation costs and to obtain a desired visual quality. However, the use of PGRs is associated with toxicity risks to humans and the environment. In many countries the availability of PGRs is restricted as few...

seedless grapes are widely grown all over the world. embryo rescue technique proved to be able to overcome the problem of embryo abortion in seedless grape breeding program. since, the efficiency of this technique is not desirable, so a lot of efforts have been done in different directions in order to improve this technique. this study was conducted in two separate experiments in which chlormeq...
