ROOTSTOCK STUDY IN COLOMBIA

Abstract

In a 21 year old orchard in Tolima (Colombia), the present study evaluated the effect of 'Arauca' (dwarfing) and 'Hilacha' (vigorous) mango genotypes - interchangeably used as rootstock and interstock - on the behaviour of varieties Irwin, Tommy Atkins and Davis-Haden as scions. 
The evaluated fruit quality parameters were: diameter, length, firmness, pH, fresh weight, total soluble solids (TSS), total titratable acidity (TTA) and TSS/TTA ratio.
 While the scions showed significant differences for all the quality parameters, no rootstock effects were detected for any of them. Fruit firmness, pH, diameter and titratable acidity were influenced by interstock, while fresh weight, fruit length, TSS and TSS/ATT ratio remained unaffected. Statistical differences were observed between all the evaluated scion/interstock/rootstock combinations for all quality parameters except for fruit firmness.
 For example, similar fruit weight values were found in comparing combinati…

ISHS STUDY ON ROOTSTOCK

ISHS Acta Horticulturae 24:Symposium on Mango and Mango CultureROOTSTOCK STUDIES IN MANGIFERA INDICA L.Authors:O.S. Jauhari, S.S. Teaotia, S.K. Upadhyay
Abstract:


Rootstocks play an important role in the propagation of plants.

It may modify form or stature, adapt a variety or species to a soil, fit in an incompatible climate, impart or resist disease to the scion, increase production, hasten maturity of crop, change the colour of the fruit, effect the flavour of the fruit, shorten life of the tree, increase the size of the fruit (3), develop vigour (Hatton, as quoted by Rogers and Beakbane, 5), effect salt tolerance (2) and influence storage capacity (7).
Very little work on this important aspect has yet been done in our country, particularly in mango. In the absence of any standard rootstock in mango, propagation is done on seedling stocks which are heterogenous in nature. 


Gunaratnam (1) recommended variety "Pullima" (Mangifera indica L.) which grows semi-wild in parts of J…

MORE BACKGROUND ON THE ATAULFO VARIETY

The debate continues and that is a good thing as debate inspires research.


Here is a link that claims that the Ataulfo came from Indonesia via Hawaii to Mexico.

The Ciruli Brothers call the Ataulfo "Champagne" (No scientific justification) ;


http://www.champagnemango.com/site/champagne


And they pay Dr. Richard J. Campbell, Senior Curator of the Fairchild tropical Botanical Gardens in Miami to justify their gaff:


http://www.champagnemango.com/site/RCampbell


Wikipedia has been corrupted into adding the Champagne brand into the public discussion of the Ataulfo cultivar:


http://en.wikipedia.org/wiki/Ataulfo_(mango)


Dr. Campbell has described the Ataulfo as a "Dog with fleas" due to it's problematic yields.


Based on information provided by the Ataulfo official website in Mexico, yields run as low as 6 tonnes per hectare. Some region yield double that number.

The ATAULFO FAMILY TREE

By Will Cavan
Executive director
IMO




May 03, 2011




Our friend and doctoral candidate, Sergio de los santos Villalobos from Mexico has made us aware of a registry process in Mexico laying claim to the Ataulfo variety.


The point that the IMO was trying to make in very crude terms is that while one can register through commercial means, names for fruit, the Scientific community is the ultimate governing body in the process.


The Manila, Oro, and Ataulfo are all decendents of the Carabao mango brought to Mexico during the 1500s in the famous Galleon trade.


The Manila - Acapulco route brought the first mangoes to Mexico by the Spanish explorers and the crews that sailed the vessels.


Acapulco was land fall and from there the fruit or seedlings were more than likely transferred overland to the ports on the gulf of Mexico.


The Chiapas region was a natural for the Carbao mango and decendents.


The highest productiuvity for the Ataulfo variety come from the Chiapas with yields as high as 25 metric tonnes pe…

DEBATE ARISES OVER ATAULFO VARIETY

LinkedInSergio de los Santos Villalobos has sent you a message. Date: 5/04/2011 Subject: MORE CONFUSION ON ATAULFO BRANDING : CHAMPAGNE VERSUS VAN GOGH? Hello Will.

How are you?.

I was reading the post named 
"MORE CONFUSION ON ATAULFO BRANDING : CHAMPAGNE VERSUS VAN GOGH?" published Tuesday, April 12, 2011.  Which says that in Mexico the Manila and Ataulfo variety are the same, but in Mexico both are differents varieties.  One more interesting thing to note is that the Ataulfo variety is NOT original from Philippines but Chiapas (México SouthEast) have the origen denomination from this variety.

Please, click the link (Mexico, Ataulfo origen denomination)

FOCUS ON IRRADIATION: SCIENTIFIC AMERICAN ARTICLE

Americans, on average, are exposed to 3.1 millisieverts of radiation a year from natural background factors such as radon gas from the Earth and cosmic rays from the universe. 


Safety experts recommend the public receive less than one millisievert a year beyond that level, although they do not include medical procedures in that limit because the procedures may bring health benefits. 


Here's a list of common sources.

DIFFICULT ROUTE TO MARKET FOR MALI EXPORT MANGOES

The normal route of containerised mango's from the Ivory Coast, Burkina Faso and Mali is from the port of Abidjan in the Ivory Coast. 


"As is known the situation in Ivory Coast was very difficult," Andre says.


 According to him it is still not easy to cool, pack and transport mangoes to Abidjan in a quick and proper way.


 "The train from the north, which normally transports the mango's has not been used for many weeks and large parts of the rails have disappeared" he continues.

CRACK DOWNS CONTINUE IN INDIA ON ADULTERATED MANGOES

In a first of its exercise this year, the health department conducted surprise raids in fruit shops, markets in Mirsahibpet in Ice House, Mylapore and Lloyds Road in Royapettah, besides the Koyambedu market. 


While the traders resisted initially, they had to give up later after the officials were firm in removing all the fruits piled up in baskets and on floors. 




The calcium carbide was stored in cloth bags and wrapped in newspapers.

ISHS ARTICLES ON LENTECIL DAMAGE

EFFECT OF PACKHOUSE PROCEDURES ON LENTICEL DISCOLOURATION OF MANGOESAuthor:R.B. CronjeKeywords:Mangifera indica L., lenticels, salt, pH, brushing
Abstract:

Handling of mangoes in the packhouse can contribute to damage on the fruit including lenticel discolouration.

Packline procedures can induce or reduce lenticel discolouration.

 Due to observations made in the 2003/04-season, trials were conducted on Tommy Atkins and Keitt fruit at Hoedspruit, South Africa, to determine the effect of different ranges of pH and electric conductivity.

 Furthermore, the effect of duration and type of brushes fruits are subjected to were studied in two different packhouses. Increasing concentrations of common salt in a water bath reduced lenticel discolouration significantly compared to the full packline treatment.

 Where fruit received hot water treatment after the salt bath, lenticel discolouration was even more reduced.

 Changes in pH of water as well as in the chemical bath did not significantly inc…

LENTICEL DAMAGE: VIEWERS COMMENTS WELCOME

EFFECTS OF POSTHARVEST HANDLING ON LENTICEL SPOTTING OF ´TOMMY ATKINS´ MANGOES FROM NORTHEAST BRAZILAuthors:G. Self, J.S. de Assis, V.C. CaronKeywords:Mangifera indica L., lenticel discolouration, chilling injury
Abstract:

Both red and black lenticel spotting reduce the value of Tommy Atkins mangoes exported from northeast Brazil to North America and Europe.

 By applying none, some or all postharvest operations to early and mid-season fruit, it was shown that postharvest handling increases lenticel spotting in a cumulative way.

Both types of lenticel spotting were caused principally by washing fruit in a calcium hydroxide solution to prevent sap burn.

Following this, the USDA phytosanitary hot water treatment reduced the potential for subsequent red lenticel spotting during cold storage, but increased black lenticel spotting.

The result of these reciprocal effects is that fruit for the EU market, which does not receive the hot water treatment, is affected principally by red spotting…

PASTEURIZATION DEFINED BY WIKIPEDIA

PasteurizationFrom Wikipedia, the free encyclopedia Pasteurization is a process of heating a food, usually liquid, to a specific temperature for a definite length of time, and then cooling it immediately. 


This process slows microbial growth in food


The process of heating wine to preserve it longer was known in China since AD.1117,[1] and is documented in Japan in 1568 in the diary Tamonin-nikki.


 The modern version was created by the French chemist and microbiologist Louis Pasteur, after whom it is named. 


The first pasteurization test was completed by Louis Pasteur and Claude Bernard in April 1864.[2]


 The process was originally conceived as a way of preventing wine and beer from souring.[3] Unlike sterilization, pasteurization is not intended to kill all micro-organisms in the food. 


Instead pasteurization aims to reduce the number of viable pathogens so they are unlikely to cause disease 


(assuming the pasteurized product is stored as indicated and consumed before its expiration date).

HWT & IRRADIATED MANGOES ARE BOTH PASTEURIZED FRUIT

BY Will Cavan
Executive Director
International Mango Organization (IMO)


Vista, California




May 03, 2011




The National mango Board (NMB) may have either unwittingly or willingly been part of one of the biggest marketing frauds in the Produce industry.


The blatant marketing efforts to promote Hot Water treated mangoes to the American public for the past six years may have over looked some very important information.


1 - The nutritional value of a mango is not the same after a Hot water dip as it is picked from the tree.


2 - Electronically "irradiated" mangoes use a cold process that may actually be better for the consumer in the long run.


Pasteurized is pasteurized whatever the means.


Hot water or electronic "irradiation" are both pasteurization processes.


The first accidental and the second intentional and very well documented.


Could it be that the NMB has been deceiving the American consumer for years?


If it turns out that these suspicions by the IMO are proven correct, the NMB a…

INDIA: SILVER AFFORDABLE, BUT MANGOES ARE OFF THE CHARTS!

Mumbai’s obsession with mangoes is a ripe one.


 Every year, mango-lovers wait for the Alphonso mangoes from Ratnagiri. 


But, the number of mangoes that made it to the city in the beginning of this season has dipped drastically compared to the last couple of years, thereby affecting the common man and restaurants in the city.
