Here is a guide to help you identify what is going on with misshapen, off-color or otherwise odd looking blackberries. But before we can talk about what causes blackberry fruit to develop odd shapes and colors, we need to discuss how blackberries form in the first place.
The word “berry” in the name blackberry is misleading as they are in fact not true berries in a botanical sense. True berries are formed from only one ovary in one flower. Blackberry flowers can have over 100 ovaries! (Oddly one example of a true berry is bananas). Instead blackberries are what is called an aggregate fruit, and their fruit is compo...
Poor Pollination/ Poor Druplet Formation Poor druplet formation can arise due to poor pollination of flowers. Pollen is produced in the stamens of the flower and must be moved to the pistils to fertilize the ovules, which will result in the druplet. If the pistil is not fertilized no druplet will form. Blackberry flowers have 100-125 pistils of whi...
Other names “Red Cell Reversion” “Red Druplet Disorder” or “Red Cell” Have you ever picked some dark-black ripe blackberries on a hot day, put them in your refrigerator and returned later only to see some of the druplets had turned back to red? This reversion of druplet color after harvest or cooling is associated with rapid temperature changes in ...
White druplet is associated with a drop in humidity and an increase in temperature. As this happens there is less moisture in the air to deflect solar radiation from directly contacting the berries. This increased solar radiation is blamed on individual or groups of druplets turning first white and then later brown in color. This disorder is often ...
Sunburn of fruit is commonly seen when daytime temperatures exceed 90 degrees or more. At these temperatures fruit in direct sunlight may reach temperatures that exceed the air temperature by several degrees (seeherefor more information). When this occurs the fruit is essentially boiled by the sun. Symptoms include druplets that look “blanched” or ...
Dr. John Clark reports seeing double berry occur on primocane fruiting varieties when there are high temperatures just prior to or during flowering. This is important to remember for us here in Arkansas as our primocane fruiters generally set flowers in the heat of summer. Occurrence is variety dependent with more double berry occurring on 'Prime-A...
Spotted Wing Drosophila
Spotted wing drosophila is a relatively new pest to blackberries in the SE. The first populations of these flies were found in Arkansas in 2012. The female flies lay eggs in ripening fruit which then develop into larvae. These flies are not native to the United States and differ from their fruit fly cousins in that they have a large serrated ovipositor that makes it easy for them to lay eggs in undamaged fruit that is still on the cane. I will attach a rough video here of a SWD larvae in a bl...
***Suspected*** These pictures are of berries suspected to have red berry mite, it has not been confirmed A distinct line between ripe black druplets and unripe red druplets that fail to ripen is a sign of the redberry mite (Acalitus essigi). As this mite feeds on the fruit it injects a toxin that results in the sharp contrast. This occurrence tend...
Stinkbugs feed on the fruit receptacle (the white part at the center of the fruit) and in doing so damage druplets as they insert their mouthparts. Stinkbugs may feed on green, red or black fruit. Generally their feeding results in only localized damage to one or two druplets. A secondary type of damage can occur if the stink bug injects its "stink...
