“…For instance, shade avoidance response in field corn contributes to crop competitiveness, particularly when combined with abiotic stresses (Page et al 2010a,b). The light environment is known to influence seed development in certain weed species (Brainard et al 2005;Mitrovic et al 2010), and perhaps also is important in wild-proso millet seed development. Alternatively, processes that influence resource capture (e.g.…”

Sweet corn is seeded under a wide range of population densities; however, the extent to which variable population density influences weed suppression is unknown. Therefore, field studies were undertaken to quantify the influence of sweet corn seeding level on growth, seed production, and post-harvest seed germination of wild-proso millet, one of the most problematic weeds in the crop. As crop seeding level increased, path analysis results indicated the crop canopy became taller and thicker, resulting in less wild-proso millet biomass, seed production, and germinability. However, at the level of individual fields, reductions in wild-proso millet growth and seed production were modest, at best, between a crop population currently used by growers and a higher crop population known to optimize yield of certain hybrids. These results indicate near-future increases in sweet corn seeding levels may play a minor role in improving weed management in individual sweet corn fields. Nonetheless, a reduction in crop populations, via weather- or management-driven phenomenon, increases risk of greater wild-proso millet seed production.

“…Mechanisms driving maternal environment-mediated differences in seed germinability include soil nutrients, temperature, photon flux density, photoperiod, and light spectral distribution (reviewed by: Roach and Wulff 1987;Gutterman 2000). Figueroa et al (2010) determined that maternal temperature effects on seed germinability of common groundsel (Senecio vulgaris L.) can occur during flower bud development, and Mitrovic et al (2010) found that maternal photoperiod effects on seed germinability of red goosefoot (Chenopodium rubrum L.) take place during the first 6 d of maternal plant growth. Thus, maternal environment effects on seed germinability potentially occur at any point during maternal plant growth and are species-specific.…”

Modification of the cropping environment to make weed seed more susceptible to fatal germination or decay processes is based, in part, on the premise that seed longevity is affected by the crop-influenced environment in which seed is produced, hereafter, called thematernal crop environment. The objective of this investigation was to determine the influence of maternal crop environment on wild-proso millet seed production, germinability, and seed coat tone (i.e., lightness), a trait previously associated with seed longevity in wild-proso millet. Maternal corn environments were established by growing wild-proso millet plants in four morphologically different sweet corn hybrids in four replicates over 2 yr. Wild-proso millet seed was collected at sweet corn harvest, enumerated, characterized for seed coat tone, and tested for germination. Principal component factor analysis reduced six sweet corn traits measured between silking and harvest into a single maternal corn environment factor that accounted for 84% of the variation among crop canopies. Functional relationships between maternal corn environment factor scores and wild-proso millet seed characteristics were clarified by fitting linear models. For each unit decrease in maternal environment factor score, wild-proso millet seed production increased 1,535 seed m−2, germination increased 2.2%, and seed coat tone was 1.8% lighter. These results show the size and germinability of wild-proso millet seed was highest in less-competitive maternal corn environments characterized by a short time to crop maturity and a small crop-canopy size.

“…Many publications have demonstrated that environmental experiences (e.g. light, nutrient, temperature, water,) of the maternal plant have influences on the performaces of the resulting progeny (Rossiter, 1996;Galloway, 2002;Etterson and Galloway, 2002;Galloway, 2005;Luzuriaga, et al, 2006;Galloway and Etteson, 2007;Uller, 2008;Wolf and Wade, 2009;Mitrovic, et al, 2010).…”

Soil fertility can influence seed production and seedling growth. This study compared seed yields, seed and seedling characteristics of eight forage legumes (Stylosanthesscabra, S. hamata, Centrosemabrasilianum, C. pascuorum, Desmanthuspubescens, D. Virgatus, Macroptiliumbracteatum and M. martii) grown on two soil types (red and yellow kandosols), of low fertility, that are widespread in the Australian tropical rangelands. Seeds of the Desmanthus species germinated most rapidly and, with M. bracteatum, produced the highest proportion of readily germinable seed. M. bracteatum seed produced on the Yellow Kandosol germinated significantly faster, as did the S. hamata from the Red Kandosol than the other species. S. scabra cv. Seca and C. brasilianum produced more readily germinable seeds from plants grown on the Red Kandosol. C. pascuorum, D. pubescens and M. bracteatum produced a higher percentage of readily germinable seeds and fewer hard seeds when grown on the Yellow Kandosol. No significant differences were found in seedling vigour or biomass allocation from seeds produced on the different soil types
