Temperate Fruit Buy, Sell, & Trade / Re: Ugni molinae
« on: January 13, 2018, 04:16:18 AM »
Hi Mikkel,

I stiill have seeds from the last harvest in October. It will be a pleasure to send you some.

Plant number six, second row.

Thank you, Chris. Your comments inspired me, to update the growth at the end of the growing season. The plants have been outside from mid-May to mid-November. May was cold and September very cool. Both month, below average. Our summer was nice and warm. Therefore, most of the growth occurred from June to August. All plants face in the same direction. Towards the equator.

can't be Yuzu Strada Montana, because my plant isn't mature yet.

Cold Hardy Citrus / Re: Yuzu... my new obsession!

The first one is definitely not a Yuzu. Some papeda, probably ichangensis.

Indeed, the plants are very different. Beside the differences already mentioned, the first plant has distinctive pale green leaves. Further, the citrusy smell of crushed leaves is not as perceivable as in the true Yuzu.

Two years ago, I bought this Yuzu.

It has quite small leaves and some large thorns.

It was only this year, when I was told, that it´s grown from seed and has not yet fruited. Therefore, I acquired another Yuzu. The new plant has much larger leaves and small thorns. I suppose, this is the Yuzu most widely grown in European citrus collections. 

A comparison of the Yuzu plants. Both are grafted on trifoliate citrus.

Many people use tropical wood and don´t know about it.

Citrus General Discussion / Re: Citrus seedlings, some odd observations.

I have found it quite amazing, that a cotyledon, broken off from the seedling plant, can live by itself for such long time.

Two weeks ago, one of my Meiwa kumquat cotyledons disappeared. This week, the second cotyledon died as well. Possibly, the soil was too wet, causing a fungus gnat infestation. The seeds were germinated in January 2015. The cotyledons reached an age of 2 years and 10 months. They neither produced leaves nor roots.

Are you sure this is a Minneola seedling?
It is good to be skeptical. Especially against oneself. I have checked all my citrus seedlings. There is nothing comparable, which could be Minneola. Now, I am confident that I didn´t mislabel both plants.

Mistakes happen. The first plant always produced grapefruit-like leaves. The second Minneola always produced elongated leaves with narrow petioles. I was surprised to see the leaves of the second plant to change to more or less grapefruit-like leaves, this season. I have crushed some leaves. The smell of both plants reminds me on Minneola, rather than grapefruit. Most leaves of Minneola in citrus idtools.org are of the elongated type. However, there is also a leaf shown, with a wide petiole.

The second Minneola with different leaf shapes.

The only mandarin-sized, store bought fruits, which gave me grapefruit-like seedling trees is Minneola. I grow two, nearly 4 years old plants. Minneola has the first year twig surface pubescent.  http://idtools.org/id/citrus/citrusid/factsheet.php?name=Minneola. However, the new growth on my plants is not pubescent. Therefore, I conclude that Minneola does not come true from seeds. Leaves can be very dissimilar. Last year’s leaves of one plant were much more elongated. This year, new leaves of both plants are about the same.

Minneola seedling plant. Thorns removed.

Temperate Fruit Discussion / Ugni molinae - autumn crop.
« on: September 24, 2017, 04:10:14 AM »
This year, my two mature Ugni molinae plants did give me a nice and plentiful crop. Both plants are about the same age and size. This gave the opportunity to compare these two varieties. The broad-leaved Ugni on the left and the Ugni Elite on the right side.



Previously, I have called the left plant also large-leaved Ugni.   http://tropicalfruitforum.com/index.php?topic=21253.msg263364#msg263364. However, I prefer the term “broad-leaved”, because the leaves are not so much larger, but considerably broader, compared to some other varieties. The plants grow in roughly 14 liter (3 gallon) pots in a sand/peat mix.
The broad-leaved Ugni gave 110 fruits, weighing altogether 52 g. Ugni Elite gave 256 fruits, weighing altogether 94 g. The average weight of one fruit compares to 0.47 g for the broad-leaved Ugni and 0.37 g for the Ugni Elite.



Bearing so small fruits, Ugni molinae is not a species for commercial fruit production, but is charming with taste and specialness. As regards taste, I prefer Ugni Elite, which is sweeter.
This was the first year, which did give a reasonable harvest. Enough, to share the fruits with my wife. Never seen any Ugni before, she asked: “Where did you get these cowberries from?” I responded:  “That aren´t cowberries. Just taste”. Interesting her comments:  “Mmmh, so good.” And after a while. “These berries remind a bit of rose pepper” (Schinus terebinthifolia, Schinus molle) “and also a bit of juniper berry” (Juniperus communis).

Tropical Fruit Discussion / Re: Feijoa - Acca sellowiana cold hardiness?
« on: September 17, 2017, 05:47:27 PM »
My two Feijoa seedling plants, planted in ground three years ago, survived this last winter with a very cold January, and passive protection only. This January 2017, minimum temperatures between -10°C (14°F) and -18°C (0°F) were officially measured on 14 nights. I intend to write a thread about passive frost protection.

Can this really be the same species, Eugenia pyriformis? It looks so different.

SoCal2warm, an argument like “There were no triploids resulting from meiosis. This suggests…” certainly will be accepted. It is also your style of argumentation which leads to dissent and disagreement.  I don´t want to discourage you. I am sure, the more you learn about genetics the better will be your conclusions. Your arguments will improve and will be than more widely accepted.

Quote
What was particularly interesting was that all of the triploids appeared to be nucellar. This suggests that the likelihood of triploid meiosis being able to produce a complete haploid gamete is far higher than a diploid gamete.

Nucellar seedlings are never derived from meiosis. Therefore, you can´t conclude from nucellar seedlings anything about meiosis.

There is a lot of misunderstanding and there are many wrong statements about citrus genetics.
 
Ilya, thank you for some corrections and your comments.

This is my only seedling. Nine months old. Seeds from Birdman. Hope it fruits by itself, when old enough. The smell of crushed leaves reminds me on bubblegum.

Solko, thank you, for showing all these different Uvaia and this huge variability. My Eugenia pyriformis plants are from one source only. They are within the range of your fast growing lanceolate leaf type, red leaf type and supposedly sweet type.

Seeds of a sweet variety of Eugenia pyriformis arrived in January 2016 from availableseeds.com. Almost all seeds germinated. Surprisingly to me, the plantlets showed a large variation, not only in growth rate, but also in plant shape. The variation in leaf pubescence is less distinct.

These are my two tallest plants in tall 3l pots, compared to the two smallest plants in 10cm square pots. June, 2017.


The smallest plant, May, 2017.


This precocious plant flowered in mid June 2017.

Hi Luc, of 30 seeds, 27 germinated. I grow them in fine sand. The sand consists mainly of pumice with some zeolite and is neutral. The topping is similar, but coarse. 10 % peat is added to achieve a more acidic soil. In summer, the plants are outside in full sun and I water almost daily, preferably with rain water.

We had a very cold period, this winter. One morning, in the glass house was frost (-1°C/ 30°F) and frozen pots. Five Eugenia mattosii seedlings defoliated. Three came back in spring, but two were lost. All the other Eugenia mattosii didn´t show any signs of stress.

Two of the spring greening plants are shown in the photo. (Plant number one and two, third row). Like many wild plants, E. mattosii shows a large variation in growth rate and possibly other characters.


Plant number six, second row.

Citradia, I didn’t give any special attention to the fertilizer and regularly fertilize either with Peters Excel 24+10+10+1 or with Kristalon 12+12+36, and never applied extra phosphorus.

Mikkel, my citrus plants are all fairly small. There wasn´t any plant suitable for pollination.

Cory, I grow around 80 citrus seedlings and have stopped now to germinate seeds, because of space reasons.
