Dormancy as exaptation to protect mimetic seeds against deterioration before dispersal
(OXFORD UNIV PRESS, 2010)
Mimetic seeds simulate the appearance of fleshy fruits and arilled seeds without producing nutritive tissues as a reward for seed dispersers. In this strategy of seed dispersal, seeds may remain attached to the mother plant ...
Seed business management in Africa

Restricted water availability during lettuce seed production decreases seed yield per plant but increases seed size and water productivity
(AMER SOC HORTICULTURAL SCIENCE, 2008)
Lettuce (Lactuca sativa) is an important vegetable crop worldwide, and its seed is commercially produced mainly under irrigation in and and semiarid regions. The objective of this study was to determine how water availability ...
Analysis of seed-germination in Piptadenia-Gonoacantha (Mart) MACBR (Leguminosae Mimosoideae)
(Inst Tecnologia Parana, 1994-01-01)
Preliminary tests indicated 20-degrees-25-degrees-C as optimum temperature range to the germination of the seeds of P. gonoacantha. Seeds germinate both under light and dark conditions, although final percentage is always ...

Crop size is more important than neighborhood fruit availability for fruit removal of Eugenia uniflora (Myrtaceae) by bird seed dispersers
(Springer, 2011-05)
For a plant with bird-dispersed seeds, the effectiveness of seed dispersal can change with fruit availability at scales ranging from individual plants to neighborhoods, and the scale at which frugivory patterns emerge may ...
