Tropical Fruit Discussion / 5 Types of Jaboticabas i got to taste in Brazil
« on: November 16, 2017, 11:41:47 PM »

This is a 24 minute interview at Instituto Plantarum botanical garden, located at Nueva Odessa, Campinas, Brazil, on November 10, 2017. The interview focuses on the botanical garden and on tropical fruits. Some questions previously suggested by forum members are included and answered by Lorenzi. In case you don't know, he is the author of Brazilian Fruits and Fruits in Brazil (Frutas No Brasil), as well as a couple of dozen other botanical books. The garden is 25 acres. Though not large the collection is very large. It is also a very beautiful place, and all the plants are very well labeled. Lorenzi was very gracious in giving me a personal tour of the place. Hope you enjoy it! let me know if you have any questions.

Tropical Fruit Discussion / Amazing Durian Year
« on: September 08, 2017, 03:28:27 AM »
This has been an amazing durian year, with the trees flowering succesively 3 times. So at the same time there are flowers, small fruits, and large fruits ready to be harvested.

Probably this is due tog an unusually dry summer. Also much more regular fertilizing than usual.
Right now i'm harvesting 4 types of durians. On the left the large Monthong, large Chanee, small seedling Chanee, and some Durio oxleyanus, that i've nicknamed the Sea Urchin Durian.

For the first time i have way too many durians, and can't eat them all. Have been taking them to some farmer's market vendors, and ofcourse eating as many as i can!


The plant is less than 2 years old.

So far the flowers have been dropping off without setting.

I've gotten this question a few times. Tourists here will see the fruit of Clusia major, aka the autograph tree (as people write their names on the large thick leaves) and they get it confused with mangosteens. If they looked at the insides they wouldn't think it's mangosteen, as the clusias have no pulp inside.

Got over 2 hours of video. Broke it up into six parts on youtube. Audio is pretty good, but slides a bit hard to see. But lots of good information. Go here for all 6 links

Tropical Fruit Discussion / The Real Problem with Durians
« on: September 24, 2016, 04:40:52 AM »
No the biggest problem with durians is not the odor, although that seems to be the only problem ever discussed. The smell discussion has become so much of an obsession that it seems to me the real bigger problems are never even brought up.
For example,this is probably the least user friendly fruit imaginable. The whole outer rind is covered in needle sharp spines. Carrying one of these fruits is hard enough. Opening them up can be right down dangerous. Some cultivars are easier to open than other. Some will pop open at the perfect ripe stage. The 2 Thai varieties i'm dealing with now are over ripe once the segments pop open. So prying them open is quite a strong laborious effort and takes a lot of skill to open one without mauling your hand.
Then there is the problem of lots and lots of sharp rind waste after eating to dispose of. One past calculation i did on a Chanee showed that 72% of the fruit is waste and only 28% is pulp. If you are buying the fruits for $5 a pound then you are in fact paying around $17.85 for the edible portion. So it's a very expensive fruit!
From a cultivation point of view the plant material is hard to obtain, hard to transport, scions stay viable a very short time and are hard to graft. The trees  are slow to bare, often taking as long or longer than the notoriously slow mangosteen. The trees get quite large and the wood is brittle and breaks easily in high winds. The trees easily succcumb to phytophthora (fungal root rot).
So why do people bother? First taste of an exquisite durian and all these problems don't seem very problematic any longer. As a fruit durian is really in a class all its own.

Tropical Fruit Discussion / First Fruiting of Red Chempadek
« on: September 24, 2016, 02:04:40 AM »
Finally got my first fruits off my own chempadek trees. This one has been a real challenge for some unknown reason. I have 4 trees, 2 just came into bearing. The other 2, also quite large, didn't even flower. The fruits on this loaded tree are similar to what MikeT posted calling Twisted Chempadek. But i didn't get them from him. The taste was rather strange and a bit chalky, also very chewy. Might just  be because they are the first fruits.

9 fruits of Garcinia prainiana randomly picked fruits weighed 11.5 ounces (326 grams).
The 39 seeds from those 9 fruits weighed 1 ounce (28 grams).
The rinds from the 9 fruits was 3.6 ounces (102 grams).
By adding weight of seeds + rinds = 4.6 ounces (130 grams),
and subtracting that from total fruit's weight then get the weight of pulp: 11.5 - 4.6= 6.9 ounces (196 grams) of edible pulp.
So the weight of the pulp 6.9 ounces is 60% of total weight of the 10 fruits. Waste (seed + rind) is 40%. So it's almost 2/3 edible pulp and 1/3 waste.

Tropical Fruit Discussion / Durian tasteoff: Chanee vs. Monthong
« on: September 23, 2016, 05:25:53 AM »
Big difference between there 2 cultivars. Monthong on left, Chanee on the right. The Monthongs are the size champions, but the Chanees (D123) are the taste and texture champions. The Chanees are a lot more creamy, often with a rich butterscotch flavor. The Monthongs are good, but not outrageous like the Chanees. This is probably not a fair test as both of these are being sampled from one coltivar tree of each.

Tropical Fruit Discussion / Mangosteen: calculating pulp to waste ratio
« on: September 21, 2016, 02:20:56 AM »
10 mangosteen fruits of randomly picked fruits weighed 34.6 ounces (981 grams).
The 13 seeds from those 10 fruits weighed .3 ounce (8.5 grams).
The rinds from the 10 fruits was 16 ounces (454 grams).
By adding weight of seeds + rinds = 16.3 ounces (462 grams),
and subtracting that from total fruit's weight then get the weight of pulp: 34.6 - 16.2= 18.4 ounces (522 grams) of edible pulp.
So the weight of the pulp 18.4. ounces is 53% of total weight of the 10 fruits. Waste (seed + rind) is 47%. So it's lees than 1/2 waste and over 1/2 edible pulp.
I did same calculation for achachairu which has only 1/3  edible pulp and 2/3 waste.

Tropical Fruit Discussion / Achachairu: Calculating Pulp to Waste Ratio
« on: September 16, 2016, 02:47:23 AM »
10 fruits of randomly picked fruits weighed 11 ounces (313 grams).
The seeds from those 10 fruits weighed 1 ounce (28 grams).
The rinds from the 10 fruits was 5.8 ounces (164 grams).
By adding weight of seeds + rinds = 6.8 ounces (193 grams),
and subtracting that from total fruit's weight then get the weight of pulp: 11 - 6.8= 4.2 ounces (119 grams) of edible pulp.
So the weight of the pulp 4.2 ounces is 38% of total weight of the 10 fruits. Waste (seed + rind) is 62%. So it's almost 2/3 waste and 1/3 edble pulp.

To be totally fair the rind can be used to make a delicious drink. Just take rinds of a couple fruits, blend in blender, let sit for a few hours, filter through screen, add sweetener, and some ice cubes. Tastes similar to a good iced tea. Very refreshing. Probably would also be great in jams or marmelade.
Ofcourse the seeds are not total waste if you plant them or trade them.
Still i feel this fruit could be improved a lot by selective process for smaller or seedless fruit. If that were done i think this fruit could become an important world wide crop. The goal should be minimum 2/3 pulp and 1/3 waste. The taste is very good, i think most people would like them, fruits keep very well, and plants are very productive. Also the fruits should ship very well.
