STUDY (INDIA) REVEALS THAT MANGO TREES ARE AFFECTED BY POLLUTION ...

Many fruit trees unable to withstand pollution

Contrary to popular belief that trees fight pollution, several species of plants including cashew, tamarind, guava, mango, custard apple, gulmohar, banyan, sapota and jackfruit, are falling prey to heavy air pollution in the industrial city of Visakhapatnam.



Researchers from the departments of chemistry, and environmental studies, GITAM University, Visakh-apatnam, have found that many plant species have been experiencing “physiological changes” due to heavy air pollutants before exhibiting visible damage to leaves. The content of chlorophyll has come down in many trees affecting the delicate process of converting carbondioxide into oxygen.




It has also affected food preparation by the trees, and thus reduction in their fruit yield and growth.


Of the 29 trees studied, only six fell under the “moderately tolerant” to air pollutants category.

None of these are tolerant to chemicals present in the air. Only those …

HARVESTING GUIDELINES FOR MANGOES ...

"Hi Will, I saw that you have much experience on this two products and for me major concern is about the brix as the fruits are showing varied brix interms of maturity the fruit is of similar maturity but some are showing low brix up to 7% to 19% what seems to be the problem. And the low brix taste like rubberise in texture and high brix is soft and sweet in taste please advise thanks "





Brix is a very important subject.

While it is clear that in mangoes atleast brix will vary by variety/cultivar, in order to capture the consumer (repeat business) 12% brix is the critical point. 
A minimum of 8.3 % Brix is the guideline that some shippers are using.
Depending upon ambient temperature at destination, some mangoes can ripen a little.
Unfortunately, at this time of year in the Northern hemisphere, that is rarely the case.

The early part of every seaon, shippers start harvesting fruit too early and as a consequence, the brix is very low.

Maturity guidelines are critical for a successf…

THE IMPORTANCE OF PROPER BRIX READINGS ...

Brix Readings, and What They Tell Us


Brix – A unit of measure used in the refractometer. When the Brix reading is divided by 2 it will be equal to the percent of crude sucrose in the plant tissue.

Refractometer – A device used to measure the refractive index of plant juices in order to determine the mineral/sugar ratio of the plant cell protoplasm.

Refractive Index of Crop juices are calibrated in percent sucrose or degree Brix.

During the growing season it is possible to check a plant for percent sucrose. A refractometer is easy to use. You will need something like a garlic squeezer for juicing the plant sample. To make a reading, place 2 to 3 drops of the liquid sample on the prism surface, close the cover and point toward any light source. Focus the eyepiece by turning the ring to the right or left. Locate the point on the graduated scale where the light and dark field meet. Read the percent sucrose (solid content on the scale).

The refractometer measures in units called Brix…
