KOCHI: Studies conducted by various institutions under the Indian Council for Agriculture Research (ICAR), as part of the National Innovations on Climate Resilient Agriculture (NICRA) initiative, has found that climate change has a significant impact on pollinators in the country, particularly in fruit and vegetable crops.





Research has come up with interesting findings, including the study on activities of Indian little bee/dwarf bee (Apis Florea) that showed a declining trend as a result of rising temperature. 








Studies conducted in the major mango belts - Andhra Pradesh, Karnataka, Tamil Nadu, Maharashtra and Uttar Pradesh - from 2011 to 2015 revealed notable variations in pollinator activity. 





“The Indian little bee showed significant negative correlation with temperature during the blossom season,”
stated a report on the studies conducted by five national institutions under the ICAR.









The report was presented at the national review workshop of the NICRA, which concluded at the Central Marine Fisheries Research Institute the other day.


“The negative correlation between the rise in temperature and the Indian little bee was further confirmed by the observation that activity of the dwarf bee declined beyond 30 per cent. But, Chrysomya Megacephala remained unaffected, making a desirable species in high temperature,” stated the report. 








Among the species tested, Chrysomya Megacephala was found to be the most efficient pollinator of mango.




“Studies conducted in the mango belt also found an interesting correlation between rise in temperature and the number of bisexual flowers. Increased temperature enhances the proportion of hermaphrodite flowers,”
  it said. 



Studies were conducted on the effects of climate change on pollinator population in four centres under the NICRA, each institute concentrating on a different crop. Apart from mango plantations, pollinator activity in cardamom, coffee, sunflower, mustard and apple plantations was also brought under scrutiny.

THE MOST SOUGHT AFTER MANGOES IN THE WORLD ....

While "Flavor" is very subjective, and each country that grows mangoes is very nationalistic, these are the mango varieties that are the most sought after around the world because of sweetnesss (Brix) and demand.

The Chaunsa has a Brix rating in the 22 degree level which is unheard of!
Carabao claims to be the sweetest mango in the world and was able to register this in the Guiness book of world records.
Perhaps it is time for a GLOBAL taste test ???

Alphonso (mango)
From Wikipedia, the free encyclopedia








Alphonso (हापुस Haapoos in Marathi, હાફુસ in Gujarati, ಆಪೂಸ್ Aapoos in Kannada) is a mango cultivar that is considered by many[who?] to be one of the best in terms of sweetness, richness and flavor. 


It has considerable shelf life of a week after it is ripe making it exportable. 

It is also one of the most expensive kinds of mango and is grown mainly in Kokan region of western India.

 It is in season April through May and the fruit wei…

Mangoes date back 65 million years according to research ...

Experts at the Birbal Sahni Institute of Palaeobotany (BSIP) here have traced the origin of mango to the hills of Meghalaya, India from a 65 million year-old fossil of a mango leaf. 





The earlier fossil records of mango (Mangifera indica) from the Northeast and elsewhere were 25 to 30 million years old. The 'carbonized leaf fossil' from Damalgiri area of Meghalaya hills, believed to be a mango tree from the peninsular India, was found by Dr R. C. Mehrotra, senior scientist, BSIP and his colleagues. 




After careful analysis of the fossil of the mango leaf and leaves of modern plants, the BISP scientist found many of the fossil leaf characters to be similar to mangifera.


An extensive study of the anatomy and morphology of several modern-day species of the genus mangifera with the fossil samples had reinforced the concept that its centre of origin is Northeast India, from where it spread into neighbouring areas, says Dr. Mehrotra. 




The genus is believed to have disseminated into neighb…
