chinese privet seed: Topics by WorldWideScience.org By the fusion of LS-SVM and Ocpls, the best prediction sensitivity and specificity were 0.900 and 0.973, respectively. The results indicate that fusion of DA and class modeling can enhance the specificity for detection of non-PDO products.

How Do Grasses Disperse Seeds? | Home Guides | SF Gate Seed Production. Many types of grass plants reproduce by means of flowers that have both male and female parts. In plants allowed to mature, the flowers are pollinated by insects, wind or birds ... PDF Seed Dispersal in Tropical Forests Activity Educator Materials Seed Dispersal in Tropical Forests OVERVIEW Although plants are immobile, they use a number of different mechanisms to disperse offspring. This exercise investigates differences in seed dispersal between two tropical tree species, one whose seeds are dispersed by wind and one whose seeds are dispersed by birds.
WIND DISPERSAL - Lightweight seeds pods will blow in the wind and my groups had a blast designing parachutes for this one. The team in the above photo made a "sled" that blew because of the sail they attached. They blew on it and as it moved forward the seeds were supposed to fall off.
Seed dispersal has following advantages * Particular species can cover more area * By covering more area chances of survival may increase because species has to adapt according to new geographical conditions * Plant can germinate when there will b...
C. Planning: Seed Dispersal Structure and Function (15 minutes) Invite students to move on to the planning stage with their group. Encourage them to draw an explanatory model of their design plan in the "Engineering Design Cycle" section of the Structures for Seed Dispersal entry in their student science notebooks.
Seed dispersal into wetlands: Techniques and results for a ... We measured composition and seed dispersal rates at a restored tidal freshwater marsh in Washington, DC, USA by collecting seed dispersing through water and wind. Seed dispersal by water was measured using two methods of seed collection: (1) stationary traps composed of coconut fiber mat along an elevation gradient bracketing the tidal range ... A trade-off between primary and secondary seed dispersal by wind We measured primary dispersal distance at varying wind speeds and release heights, and quantified secondary dispersal potential as the threshold wind speed for seed movement on four ground surfaces. Contrary to our expectation, we found a context-dependent trade-off between primary and secondary wind dispersal.
Seed dispersal - Wikipedia
One of the most common is wind. Seeds dispersed by wind have small wing attachments, or are so light they are easily carried by the wind and can drift, sometimes for miles, to seek out a location with enough freedom and nutrients to grow. Water dispersal works in a similar way, but the seeds have different characteristics. Seed And Fruit Formation - Seed Dispersal - Biology
