More information: Chapter 7 Small Fruits and Brambles: Strawberry Pollination (pages 679-688 in: USDA Insect Pollination of … Also the more plants you have, the better the chances of pollination and a prolific harvest. The same grower who sent the photo in Fig. The first reason is the most likely and has to do with lack of pollination. 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. 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. Misshapen strawberries are quite common. Strawberries that are lobed, especially seedy and juiceless on one section, and lopsided are likely improperly pollinated. Strawberries can form misshapen fruits if inadequate pollination occurs. Poorly pollinated berries tend to be small with a rough, dimpled, seedy appearance similar to that of boron deficiency. They have multiple ovules per receptacle where the fruit is formed. But, yes, there is no doubt a reason for misshapen strawberries like these. Lygus feeding results in variable seed size Poor pollination. 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. But, yes, there is no doubt a reason for misshapen strawberries like these. Strawberries are self-pollinating but form better fruits when a (ontinued on page 5) Poor Pollination Above is an example of a parthenocarpic Although raspberry flowers are self pollinating, bee activity is still responsible for 90-95% of pollination. 4) Fig. Hand pollinate with a paintbrush if needed. There are many causes of poor formation and misshaping of raspberry fruit, including bad weather, genetics or viruses. 3, had a question about lygus injury. The strawberry receptacle may have up to 500 ovules per berry. Misshapen fruit due to poor pollination can readily be distinguished from those damaged by tarnished plant bugs by examining the seeds. Poor pollination may have contributed to low set in some locations. This could be caused by poor pollination or even very windy conditions as fruit set occurs. Poor pollination. There are many causes of poor formation and misshaping of raspberry fruit, including bad weather, genetics or viruses. Lygus bugs damage fruit by puncturing individual seeds; this, in turn, stops development of the berry in the area surrounding the feeding site. There are three reasons for deformity in strawberries with a possible fourth put forward for discussion: Poor pollination. 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. Most commonly, misshapen strawberries during spring result from poor pollination. Bees are the best pollinators of strawberries, so encourage them to take up residence in your yard. Small seedy fruit and uneven growth are symptoms of poor pollination. Deformed berries are often due to poor pollination. Although raspberry flowers are self pollinating, bee activity is still responsible for 90-95% of pollination. You will see these as “seeds” on the outside of the strawberry fruit which are called achenes. A minimum of ten plants is good, but twenty will be better. Another issue may have been pollination. 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. 4. Strawberries are aggregate fruits. 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. Improperly pollinated however, the most likely and has to do with lack of pollination reason misshapen!
