Michigan State University has long been a resource for small farms in Michigan. Thanks to a $750,000 grant from the United States Department of Agriculture, MSU will be able to help even more fledgling farmers get their start.

“This grant will enhance and create a vibrant network of farmer training across Michigan to help them negotiate the first five years of their endeavor,” said Mike Hamm, C.S. Mott Professor of Sustainable Agriculture and Director of MSU Center for Regional Food Systems. “Our programs will cater to different perspectives and needs while moving everyone who desires to farm along the path of building a viable business."

As part of the grant, the MSU Student Organic Farm will expand its Organic Farmer Training Program. Without programs like this, burgeoning farmers like Joannee DeBruhl, farm manager of Stone Coop Farm, may not have ever gotten her start.

DeBruhl, who spent much of her career in the insurance business, was laid off in 2009. Looking for a major change, she gravitated toward community gardening and eventually enrolled in MSU’s Organic Farmer Training Program.

“The program was great; it gave me lots of hands-on training and showed that it was possible and not just a dream,” DeBruhl said. “I think the USDA grant will be a huge benefit for small farmers because there’s not much money out there to help them get started.”

Training and help with startup costs are crucial, and this grant will be managed well by MSU, she added.

Key to the project is MSU’s partnership with Michigan Food and Farming Systems, which runs the Women in Agriculture Collective Farming Initiative at Genesys Health System in Genesee County. This partnership will develop site- and people-appropriate training programs that help beginning women farmers build a successful business.

In addition to women, the grant also will develop training programs for Hispanic farmers. The number of Hispanic farms in Michigan continues to grow, and MSU will assist this historically underserved farmer population through training and site development assistance at the Farmers on the Move Cooperative in Battle Creek.

MSU also will launch new, and improve existing, programs that target the biggest challenges facing small-farm viability – land access, capital access, market access, business planning and strategizing for scaling up production.

Additional MSU contributors helping with this grant include: Jeremy Moghtader, Shakara Tyler. Michelle Napier-Dunnings, with Michigan Food and Farming Systems, also will be contributing to these efforts.

The anatomy of petal drop in sunflowers

Study finds cell division at abscission zone of short-lived cultivar occurs earlier than in long-lived variety

ITHACA, NY - Despite their consumer popularity as cut flowers, some sunflowers are difficult to market because of their tendency to lose petals soon after their flowers open. This characteristic, "petal drop", which in some varieties can occur within a day of the flowers' opening, ruins the appearance of sunflowers and damages their market value. Sunflower growers interested in finding cultivars that are less prone to this condition have had limited information about petal drop, but a new study in the Journal of the American Society for Horticultural Science contains findings can inform both sunflower breeding programs and consumers' choices.

Joyous Suiyigheh Tata and Hans Christian Wien from the Department of Horticulture at Cornell University studied the abscission zone, a differentiated region where petal drop initiates, at the base of petals of sunflower florets in two different cultivars. "We wanted to determine if differences in the abscission zone among sunflower cultivars were correlated with differences in timing of petal drop," the authors said. Two pollen-free hybrid sunflower cultivars were selected for evaluation: Procut Bicolor, which loses its petals easily, and Procut Yellow Lite, which holds its petals much longer.

For the first experiment, the researchers measured separation force for the two sunflower cultivars using a modified soil cone micropenetrometer, an apparatus that measures separation forces in the opposite direction. "The separation force experiments showed that detachment forces switched from an initial high to low in both cultivars because of the maturation of the separation layer. This maturation occurred earlier in the cultivar that is first to lose its petals (Procut Bicolor)," the authors said. They noted that there were no force readings for the short-lived cultivar on day 9 and day 12 because the flower had already wilted.

"In the second experiment, we studied the changes in the anatomy of the petal-achene juncture of the two cultivars," the scientists explained. Three stages from Procut Bicolor (PBC) and four stages from Procut Yellow Lite (PYL) were studied. These stages represent a time course with physiological relevance; when the flower just opens (anthesis), 8 days (the end of flower life for PBC), and 12 days (the end of flower life for PYL). The study also included analyses of petal anatomy at 4 days after harvest. The "end of flower life" was defined as the time when detachment force equals zero; when simply touching the petals caused them to fall off easily. Results of the analyses showed that cell division at the abscission zone of the short-lived cultivar occurred earlier than in the long-lived cultivar. "These results reveal that there was a difference in timing in the formation and maturation of the separation layer between the two cultivars," the authors said.

Interestingly, analyses showed that the mean "break strength" of cultivars in the yellow group was higher and significantly different from cultivars in the orange and bicolor groups, which were in turn higher than cultivars in the red group. Mean vase life (12 days) of the sunflowers in the yellow group was longer than cultivars in the orange group (10 days), while the vase life of the orange group was longer than cultivars in the bicolor group (9 days). The vase life of the red cultivars was shortest at 8 days. "We found that vase life has a strong relationship with flower color; the darker cultivars in the study had a shorter vase life compared with the lighter cultivars," the scientists remarked.

"The anatomy of petal drop in sunflower is similar to the majority of established descriptions in other species; the process involves the separation of four to five rows of smaller transversely oriented cells that lay horizontally across the diameter at the juncture between the petal and the achene, the separation layer," the authors said. "The concept that the timing of the maturation of the separation layer in the abscission zone helps determine the timing of petal drop is strongly supported by both the physical and anatomical investigations."

The authors concluded that the regression equation and results from the petal detachment force experiments can be used to screen sunflower cultivars in order to determine groupings of short-lived vs. long-lived cultivars. They said that the study contains beneficial information for sunflower breeding programs working to improve the breed's longevity, which can ultimately lead to increased sunflower sales.
