Excerpt from Spurred Anoda: A Potential Weed in Southern CropsIn our Stoneville study, mature seed capsules and seeds were observed 13 weeks after emergence (may 29, Peak capsule and seed production occurred 17 weeks after emergence (fig. One plant produced capsules with seeds. In North Carolina, spurred anoda grown at densities of 10 plants per meter of row produced an average of 159 seed capsules per plant, with an average of 14 seeds per capsule (solano et al. L976b). The differ ences in seeds per plant between the Mississippi and North Carolina studies were due to intraspecific competition, or plant density.Since spurred anoda germinates and emerges in the field until October and since the mature seed develops a hard impermeable coat, it is important to know the number of mature seeds produced by plants emerging during the late summer and early fall prior to frost. At Stoneville, plants emerging from seeds planted July 27 produced 828 and mature seeds by October 11 and 24, respectively (table When planting was delayed 2 weeks, only 376 seeds per plant were produced by November 5. Spurred anoda planted August 24 and September 14 produced only 39 and 12 seeds per plant, respec tively, by November 5. Even so, the small quan tities of seed produced by November 5 from August 10 and later plantings were adequate to produce substantial plant populations the following year.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
