Also the more plants you have, the better the chances of pollination and a prolific harvest. You will see these as “seeds” on the outside of the strawberry fruit which are called achenes. Poorly pollinated berries tend to be small with a rough, dimpled, seedy appearance similar to that of boron deficiency. Small seedy fruit and uneven growth are symptoms of poor pollination. A minimum of ten plants is good, but twenty will be better. Periods of cool rainy weather were common in early May during the early bloom period. The first reason is the most likely and has to do with lack of pollination. Strawberries are self-pollinating but form better fruits when a (ontinued on page 5) Poor Pollination Above is an example of a parthenocarpic This is also discussed in Dr. Burrack’s blog: “ Lygus feeding does result in variable seed size and can, therefore, be distinguished from poor pollination in strawberries.” (Fig. Poor pollination may have contributed to low set in some locations. Poor pollination is often very common in the first picking of spring fruiting strawberries in the southeast, when weather is often less suitable to bee activity. Lygus bugs are one of the causes of irregularly shaped, cat-faced strawberries; another cause may be poor pollination, which results in small undeveloped seeds. There are three reasons for deformity in strawberries with a possible fourth put forward for discussion: Poor pollination. There are many causes of poor formation and misshaping of raspberry fruit, including bad weather, genetics or viruses. Misshapen fruit due to poor pollination can readily be distinguished from those damaged by tarnished plant bugs by examining the seeds. The strawberry receptacle may have up to 500 ovules per berry. There are many causes of poor formation and misshaping of raspberry fruit, including bad weather, genetics or viruses. Strawberries that are lobed, especially seedy and juiceless on one section, and lopsided are likely improperly pollinated. Bees are the best pollinators of strawberries, so encourage them to take up residence in your yard. Most commonly, misshapen strawberries during spring result from poor pollination. Lygus bugs damage fruit by puncturing individual seeds; this, in turn, stops development of the berry in the area surrounding the feeding site. Cold temperatures, rainy and windy weather can slow bee activity, so you might not get as many pollinations if the flowers are blooming at an inopportune time. However, the most common cause is a lack of pollinators, such as domestic and wild bees, during the flowering period. There are three reasons for deformity in strawberries with a possible fourth put forward for discussion: Poor pollination. Poor pollination. Another issue may have been pollination. 4) Fig. Lygus feeding results in variable seed size Although raspberry flowers are self pollinating, bee activity is still responsible for 90-95% of pollination. However, the most common cause is a lack of pollinators, such as domestic and wild bees, during the flowering period. But, yes, there is no doubt a reason for misshapen strawberries like these. But, yes, there is no doubt a reason for misshapen strawberries like these. Misshapen strawberries are quite common. More information: Chapter 7 Small Fruits and Brambles: Strawberry Pollination (pages 679-688 in: USDA Insect Pollination of … The same grower who sent the photo in Fig. The first reason is the most likely and has to do with lack of pollination. Poor pollination. Strawberries are aggregate fruits. Deformed berries are often due to poor pollination. This could be caused by poor pollination or even very windy conditions as fruit set occurs. Strawberries can form misshapen fruits if inadequate pollination occurs. Although raspberry flowers are self pollinating, bee activity is still responsible for 90-95% of pollination.
