Exempel på meristem

• Seedling dynamics of a tropical tree: impacts of herbivory and meristem damage.

• Moreover, studies describing effects of herbivores on population dynamics and community structure refer to only seed predation, seedling meristem herbivory or grazing.

• It could not be determined, however, what degree of water loss had occurred in hypocotyl cells compared with those of meristems.

• Each spectrum was obtained for a globoid from a different spongy ground meristem cell.

• The data suggest that the embryo moisture content may control the extent of mitotic activity in the meristems of maturing seed.

• The rot affects the meristem in young palms more frequently than in adult palms.

• The lack of axillary meristems on the main stem make palms inherently susceptible to die standing from insect attacks.

• For instance, asynchronous differentiation of rachis branch meristem from the primary inflorescence meristems is acropetal.

• In contrast, asynchronous rachis branch development (acropetal differentiation of rachis branch meristems and/or spikelet meristems) progresses basipetally.

• Asynchronous differentiation of spikelet meristems from a single rachis branch meristem is acropetal.

• This resurrection capacity is not restricted to the main meristems of these plants.

• We reduced variability by eliminating from the study cells of the two protoderm layers, the provascular regions and the palisade ground meristem.

• High mortality during these periods was related to flowering of adult plants and apical meristem damage.

• In many cases, the rot stops spreading before it reaches the meristem.

• The majority of regrowth occurred during the same 6-mo period as the loss of the apical meristem.
