Effect of Pinching and Growth Retardants on Growth and Flowering in African Marigold Cv. Pusa Narangi Gainda
A study on the effect of pinching and application of growth retardants on growth and flowering in African marigold cv. 'Pusa Narangi Gainda' was carried out in the experimental field of Division of Floriculture and Landscaping, Indian Agricultural Research Institute, New Delhi. Treatments comprised pinching, CCC applied at 1000ppm, 1500ppm or 2000ppm, MH at 500ppm, 1500ppm or 2000ppm; B-9 at 500ppm, 750ppm or 1000ppm, and a Control (no pinching). CCC at 2000ppm recorded minimum plant height (46.0cm), maximum plant-spread (56.0cm) and maximum number of branches (19.0), whereas, maximum plant height (67.0cm), minimum plant-spread (29.66cm) and minimum number of branches (5.33) were recorded in Control (non-pinching). As for flowering and yield, application of CCC at 2000ppm recorded maximum flowering-duration (25.33 days), number of flowers per plant (40), single-flower weight (119.46g), flower yield per plant (408.10g), flower yield per unit area (17.83t/ha) and seed yield per plant (17.80 g), Maximum flower diameter (7.93cm) was recorded with application of CCC 2000ppm, whereas, minimum was recorded with pinching (6.2cm). Spray of growth retardants enhanced flower yield compared to that in Control (no pinching). Maximum shelf-life of flower was recorded with CCC 2000ppm (3.66 days), whereas, minimum was recorded with pinching and non-pinching (2.33 days). Thus, application of CCC at 2000ppm is superior to other treatments tested for increasing flower yield in marigold
Overview of Bivalve fisheries of India
Bivalves are commercially important molluscs belonging to the Class Bivalvia
(Lamellibranchia or Pelecypoda), which is the second largest Class under the
Phylum Mollusca. They are bilaterally symmetrical, laterally compressed
molluscs, with extensive mantle lobes which secrete a single shell composed
of two valves. Bivalves are reported to have originated in the euryhaline
w a rm shallow coastal waters prior to their gradual invasion to estuarine,
brackish, fresh and all the reaches of marine, ecosystems. Although, none
have invaded the land, the bivalves are more successful in marine and a few
species are found in freshwater habitats. Nearly 652 species of marine
bivalves are reported from India, of which 88 species are endemic to Indian
waters
Provisional guidelines for bivalve farming in India with emphasis on meeting hygiene and public health requirements
Bivalve molluscs such as clams, mussels, oysters and
scallops are prime seafood that contribute to capture
and aquaculture production in many countries. Globa
bivalve aquaculture production has increased two-fold
from 7.08 to 14.72 million tons during 1995-2015. While
production has increased, the share of bivalves entering
the international trade is relatively small, due to the
stringent regulations on their imports associated with
the food safety issues in major markets. The regulatory
regime for bivalve products, under live or processed
category, varies with the importing country
Mussel farming
The mussels are bivalve molluscs typically inhabiting the territorial to shallow sub littoral zones of the coastal areas
