Over the last few years, we have been experimenting with the idea of applying ethylene-releasing plant growth regulators (PGRs) to the rootzone as a substrate drench. This is a rather radical idea for floriculture production overall and flowerbulb forcing in particular. In this newsletter, we’ll review ethylene as a growth regulator, discuss the commercialy available ethylenereleasing PGRs and ...

Floriculture in India is estimated to cover an area of 2.55 lakh ha with a production of 17,54,000 MT of loose flowers. Nearly 77 % of the area under floricultural crops is concentrated in seven states comprising Tamil Nadu, Karnataka, West Bengal, Maharastra, Haryana, Uttar Pradesh and Delhi. Among different states, Tamil Nadu ranks first in area followed by Karnataka, West Bengal and Maharast...

Eucalyptus gunnii leaves can appear as green or glaucous phenotypes with the latter more desirable for floriculture. The epicuticular wax from these two types were compared morphologically using environmental scanning electron microscopy, chemically using gas chromatography, and molecular markers were found to distinguish the two types using RAPDs and bulked segregant analysis. Both phenotypes ...
