Situación actual - moderno o muy utilizado

El cultivar de zarzamora Prime-Ark 45 (APF-45) se introdujo para ampliar las opciones de este innovador tipo de zarzamora que fructifica en primocanos con espinas.
Este tipo de mora de dos estaciones fructifica en cañas de la estación actual (primocanes) y en cañas de la segunda estación (floricanes), proporcionando potencialmente dos temporadas de cultivo, tanto frutas tradicionales de verano como producción de finales de verano a otoño. Los cultivares tradicionales de mora fructifican en floricanes, lo que requiere que las cañas pasen el invierno para producir una cosecha. Este hábito de fructificación tiene el potencial de ampliar la producción de moras de forma similar a lo que ha ocurrido con las frambuesas rojas de fructificación primaria.
Además de tener cañas sin espinas, esta Prime-Ark 45 produce bayas grandes con buen sabor y es de maduración muy temprana en floricanes. Las bayas de Prime-Ark 45 no muestran un potencial de almacenamiento poscosecha excepcional, y no se recomienda para el mercado de transporte.
La longitud media de los primocanes es de unos 2 m. Los primocanes son fuertes y vigorosos, pero espinosos. A las plantas les gusta la colocación al sol. Las 45 bayas de Prime-Ark son de tamaño medio-grande, el peso medio de la baya es de unos 4-6 g. El color es negro. Cada planta produce grupos de bayas, como un racimo de uvas. La primera cosecha comienza a formarse en los primocanes a mediados de junio y continúa de tres a cuatro semanas. Durante esta primera temporada de cosecha, Prime-Ark 45 produce intensamente primocanes, que pronto comienzan a florecer. La segunda temporada de cosecha continúa hasta las primeras heladas.
Una vez finalizada la segunda temporada de cosecha, la Prime-Ark 45 requiere un refugio invernal contra las heladas y el viento frío, ya que la resistencia al frío de esta variedad de mora es moderada, de unos 13..17 C bajo cero.

¿Cómo cultivar la mora Prime-Ark 45 (Primer-Arco 45)?

1. Avoid wet area when planted new bushes;
2. Annual spring nitrogen fertilization (56 kg/ha) using ammonium nitrate;
3. Additional fertilization (23 kg/ha) after the floricane crop production is completed in July;
4. Tipping primocanes at 42 inch height two times each season usually in mid-June and late July or early August;
5. Dormant pruning of primocane-fruiting plants must include removing dead floricanes and removing primocane tissue to a point below the fruiting (flowering) area on the primocanes;
6. Dormant pruning of floricane-fruiting plants must include removing dead floricanes and pruning lateral branches to ~ 0.4 m in length;
7. A single application of iron sulfate in late fall (October) and lime sulfur (94 L/ha) at budbreak in early spring;
8. Plant spacing at least 0.6 m;
9. Use sun shelters.

Addon to my previous review. Drought-resistant, has tasty berries. The main drawback is its thorns and termination of pollination at the air temperatures over 30 C.

Dr. John R. Clark describes Prime-Ark 45, the first primocane-fruiting blackberry with high quality storage and shipping characteristics for the commercial fruit industry. Prime-Ark 45 is the third of four primocane-fruiting blackberries released by the University of Arkansas System Division of Agriculture.

We love prime ark 45’s they are beyond my best expecations. Not often does something exceed what we expected to extend the blackberry season. These pictures were taken September 10th. They show no signs of slowing down. They are still blooming! Prime ark freedom continue to be a dissapointment so far at my location. When people taste these test crop berries 100% of the time they say they are very good but not as good as my family heirloom berries that ripen in July. For extending the blackberry harvest these are exactly what you want. They are hardy but as hardy as the heirlooms. These must be very well cared for the first two years to get them established. My mother came out to look at them and after eating some she proclaimed they were pretty good for a tame berry but nothing like the family heirloom we grow. I mentioned to her that perhaps crosses between the two would improve the genetics on both. She looked at me like i suggested releasing tazmanian devils for a breeding project. If the heirlooms of my grandfathers blackberries pick up the everbearing gene naturally they would be unstoppable because the seeds readily sprout as it is with wide gentic variation.

In my experience primeark45 in Kansas is truly everbearing with large , good tasting berries. Freedom thornless does ok but not as good as 45. I did not give them much special care to test how they truly would do in a really big planting. There are many more productive berries that can be planted if a single large crop is wanted. 45 is what should be planted for s continuos crop. The photo above was 25 days ago when these were mostly small berries and blooms. These test crops of Prime ark 45 turned out very good! Freedom planted at the same time did not produce berries. Primeark 45 had some large berries even on these smaller plants. The berries started ripening in Late June (ate a few) and are still producing today on July 4th! They may produce up until the time of my main blackberry harvest on July 20th. These are all good signs but we will see what fall brings! These are Very very promising black berries! Flavor and disease resistance have been very good. These look like they will fit my needs extending the blackberry harvest.

This cultivar I've planted in last year at the middle of summer. Prime-Ark 45 almost immediately started to produce primocanes and bloom. Thorns number were less than Kiowa. I've received harvest from floricanes and from primocanes. Last harvest was at the beginning of October, but some drupelets of berries were not ripen.
