Costs of Reproduction

We have shown that reproduction lowered the rate of biomass production and shortened the total life period by inducing senescence of the whole vegetative body. These negative effects of reproduction on subsequent growth and survival have been termed as costs of reproduction (Williams, 1966). It has been suggested that plants maximize their fitness by minimizing the cost of reproduction (Reekie and Bazzaz, 1992 Bazzaz, 1997). The cost of reproduction has been classified into two categories...

Allometry Theory and RA

How can allometry theory contribute to our understanding of the many patterns of reproductive allocation observed in plants Previous studies have used allometric equations to relate density to mean plant mass (self-thinning White and Harper, 1970 White, 1981), the height of the trees to the diameter of their trunks (Whittaker and Woodwell, 1968), vegetative growth to organ mass (Niklas and Enquist, 2002a,b), and seed output to seed mass (Kawano, 1981). The well-known power function Y (Xa...

Plasticity of Meristem Allocation

Plasticity of meristem allocation confers plants with the ability to avoid meristem limitation. If a plant can adaptively change the meristem allocation according to the variability of resources, it can take advantage of resource pulses. No plants have totally canalized meristem allocation, but it is possible that plasticity is constrained by plant allometry. If meristem allocation follows simple allometric rules, the proportion of each type of meristem will change according to a simple...

The Impact of Meristem Allocation on Reproductive Allocation

Meristem allocation models suggest that plant allocation to different types of meristems may affect reproductive allocation. According to the models, early allocation to reproductive meristems instead of growth meristems may reduce the expansion of the shoot system and in this way later allocation to reproduction. The result is common for many allocation models, which predict a trade-off between early and late allocation to reproduction Roff, 1992 . In meristem allocation models, the...
