Fruits: Kinds and Terms
FRUITS: KINDS AND TERMS THE IMPORTANT PART OF THE LIFE CYCLE OFTEN IGNORED Technically, fruits are the mature ovaries of plants that contain ripe seeds ready for dispersal • Of the many kinds of fruits, there are three basic categories: • Dehiscent fruits that split open to shed their seeds, • Indehiscent dry fruits that retain their seeds and are often dispersed as though they were the seed, and • Indehiscent fleshy fruits that turn color and entice animals to eat them, meanwhile allowing the undigested seeds to pass from the animal’s gut We’ll start with dehiscent fruits. The most basic kind, the follicle, contains a single chamber and opens by one lengthwise slit. The columbine seed pods, three per flower, are follicles A mature columbine follicle Milkweed seed pods are also large follicles. Here the follicle hasn’t yet opened. Here is the milkweed follicle opened The legume is a similar seed pod except it opens by two longitudinal slits, one on either side of the fruit. Here you see seeds displayed from a typical legume. Legumes are only found in the pea family Fabaceae. On this fairy duster legume, you can see the two borders that will later split open. Redbud legumes are colorful before they dry and open Lupine legumes twist as they open, projecting the seeds away from the parent The bur clover modifies its legumes by coiling them and providing them with hooked barbs, only opening later as they dry out. The rattlepods or astragaluses modify their legumes by inflating them for wind dispersal, later opening to shed their seeds. -

Estimating Soil Seed Bank Characteristics in Ponderosa Pine Forests Using Vegetation and Forest-Floor Data
Estimating Soil Seed Bank Characteristics in Ponderosa Pine Forests Using United States Department of Agriculture Vegetation and Forest-Floor Data Forest Service Rocky Mountain Research Station Research Note Scott R. Abella and Judith D. Springer RMRS-RN-35 September 2008 Abstract—Soil seed banks are important for vegetation management because they contain propagules of species that may be considered desirable or undesirable for site colonization after management and disturbance events. Knowledge of seed bank size and composition before planning management activities facilitates proactive management by providing early alerts of exotic species presence and of abilities of seed banks to promote colonization by desirable species. We developed models in ponderosa pine (Pinus ponderosa) forests in northern Arizona to estimate the size and richness of mineral soil seed banks using readily observable vegetation and forest- floor characteristics. Regression models using three or fewer predictors explained 41 to 59 percent of the variance in 0- to 2-inch (0- to 5-cm) seed densities of total and native perennial seed banks. Key predictors included aboveground plant species richness/10.8 ft2 (1 m2), litter weight and thickness, and tree canopy type (open or closed). Both total and native perennial seed banks were larger and richer in plots containing: (1) species-rich understories, (2) sparse litter, and (3) tree canopy openings. A regression tree model estimated that seed bank density of native perennials is 14-fold greater if aboveground plant richness exceeds eight species/10.8 ft2, forest-floor leaf litter is < 1 inch (2.5 cm) thick, and tree canopies are open. Introduction Soil seed banks are important for vegetation man- agement in ponderosa pine forests in at least four ways. -
BLM Seeds of Success Program
collect • evaluate • establish • grow • store • restore Seeds of Success (SOS) was established in 2001 by the Bureau of Land Management (BLM) in partnership with the Millennium Seed Bank Project (MSB) to collect, conserve, and develop native plant materials for restoration across the United States. The initial partnership between BLM and MSB quickly grew to include many additional partners, such as botanic gardens, arboreta, zoos, and municipalities. These SOS teams share a common protocol to coordinate seed collecting and species targeting efforts. SOS is a vital part of the Native Plant Materials Development Program. To date, SOS has over 12,000 native seed collections in its National Collection. This material is used for restoration projects, native plant materials development projects such as germination trials, common garden studies, and protocol establishment. Portions of each collection are also held in long-term storage facilities for conservation. 2010 was an especially productive collection year, made possible by an influx of $1.25 million in American Recovery and Reinvestment Act funds. These funds put an additional 43 collectors on the ground, allowing SOS to nearly double collection capacity. 3,000 ~2,700 SOS has partnerships nationwide for permits to collect on 40 USDA Forest Service National Forests, 10 U.S. Fish & 2,500 Wildlife Service National Wildlife Refuges, 6 Department 2,000 of Defense areas, The Nature Conservancy’s lands and 1,474 1,504 1,500 multiple state and local lands. Non-federal SOS partners 1,235 1,208 1,012 1,044 1,058 have made significant collections in the Midwest, Texas, 1,000 685 447 Eastern U.S., and San Diego County. -
Seeds & Seed Practices
A Preliminary Report on Seeds & Seed Practices across the United States For too many people and communities around the world, patenting seeds and the genetic manipulation of seeds the dominant agricultural model is causing economic for corporate profit. We must shed light on and uphold hardship, the destruction of biological diversity, and the the rights of all of life to grow, evolve, and be present in exploitation of earth’s ecological commons. It is a model ecology, even the whole of the Earth. Seeds are one of the based on the commodification of life. We can no longer foundational elements to our food system and must be continue the status quo that enables multi-national defended because they affirm our lives, our very suste- corporations to corner our food system and our seed nance, and our relationship to place, culture, plants, and commons. Every element that is foundational to life (food, all of nature. water, land, air) is under threat of privatization and mar- ketization by an economic order that seeks to profit and This report is written to examine current seed culture, sav- own our common wealth. ing, keeping and sharing, and seed advocacy across the United States and North America. This is an initial report The growing global movement by peasants, growers, of the seed survey sent out by the Rights of the Mother farm workers, fisherfolk, pastoralists, indigenous peoples, Earth/Defense of the Commons Workgroup of the U.S. urban growers, food system policy advocates, and human Food Sovereignty Alliance in summer 2013, to deepen the rights activists has born witness to a growing trend of discussion around seeds and the rights of nature. -
Plant Anatomy Lab 13 – Seeds and Fruits
Plant Anatomy Lab 13 – Seeds and Fruits In this (final) lab, you will be observing the structure of seeds of gymnosperms and angiosperms and the fruits of angiosperms. Much of the work will be done with a dissecting microscope, but a few prepared slides will also be used. A set of photocopied images from the plant anatomy atlas will be available as a handout. You can use the handout to help you identify the various structures we will be looking at in seeds and fruits. Also, a fruit key is available as a separate handout. Remember that we will be considering only a small fraction of the structural diversity present among seeds of gymnosperms and the seeds and fruits of angiosperms. Seeds Gymnosperms Obtain a prepared slide of an immature pine ovule and of a mature pine ovule. You will be able to tell them apart from the following observations. • Looking at the immature ovule, you will see a megagametophyte with one or more archegonia at the end near the micropyle. The egg inside may or may not have been fertilized. • Also find the nucellus and integument tissues. Next look at a slide of a mature ovule. Instead of the megagametophyte, you will find a developing embryo. As part of this embryo, find the • cotyledons, • the radicle (embryonic root), and the • shoot apical meristem. Depending on its age, you may also notice procambial strands running between the embryonic root and the shoot apex. Points to consider: We might say that gymnosperms and angiosperms have seeds but only angiosperms have fruits - Why is that? Why don’t we consider the seed cone of a pine tree a fruit? Angiosperms Dicot Obtain a bean pod. -
