Eragrostis tef seed size tef tef agronomy
2010/9/10
Tef [Eragrostis tef (Zucc.) Trotter], the indigenous Ethiopian cereal, has a very minute seed size, yet it has a strong bearing both on the preferences of farmers for planting material and consumers a...
Seed Dispersal by Frugivorous Birds in a Coniferous Plantation
mixed conifer/broad-leaved forest frugivorous bird Japanese cedar plantation seed dispersal seed rain
2009/8/28
In order to evaluate the role of frugivorous birds in the dispersal of broad-leaved tree seeds in a plantation of Japanese cedar, Cryptomeria japonica D. Don, we monitored seed rain with 120 seed trap...
Characteristics and Effectiveness of Glasshouse Miniature Seed Orchards in Cryptomeria japonica D. Don
Cryptomeria japonica D.Don glasshouse miniature seed orchard pollen contamination
2009/8/28
We produced seeds of Cryptomeria japonica trees in a glasshouse miniature seed orchard to prevent pollen contamination. In the glasshouse, male flowers shed pollen from February 4 to March 27, 2002, w...
Effect of Seed Caching by Parus varius on Germination in Styrax japonica
Japanese snowbell saponin scatterhoard seed dispersal varied tit
2009/8/28
We examined the seed dispersal and germination of Styrax japonica to determine the effects of the fruit pulp involving saponin and its removal by the varied tit (Parus varius) on the seed germination ...
Seed Rot of Post-dispersal Prunus verecunda Seeds Induced by Sucking of Macroscytus japonensis
burrower bug cherry Cydnidae fungus seed predation
2009/8/28
We examined pre- and post-dispersal seed predation in Prunus verecunda in a deciduous broad-leaved forest, northern Japan. Few seeds died before dispersal, but most seeds were preyed upon by small rod...
Effects of Snow Cover on Seed Survival and Seedling Distribution of Beech Protection from Seed Predation by Rodents
beech tree regeneration seed predation seedling bank snow cover
2009/8/24
Beech trees often dominate the natural forests in northeast part of Japan. This is partly attributable to heavy snow environment in these districts. Deep snow cover during winter season may contribute...
Reproductive Ecology of Macroscytus japonensis as a Post-dispersal Seed Predator
burrower bug Prunus verecunda seed cache seed predation seed rot
2009/8/24
We examined the reproductive ecology of the burrower bugs (Macroscytus japonensis) that suck seeds of cherry (Prunus verecuude) dispersed on forest floors and induce rotting of the seeds. The burrower...
