Fitness analysis of seed and vegetative reproduction of clonal tree Symplocos laurina
      
There are two ways for Symplocos laurina to propagate: clonal reproduction and sexual reproduction.
      
But clonal ramets took advantage both in terms of number and space.
      
Therefore, clonal propagation predominated in such an environment.
      
A bottleneck in sexual propagation appeared at the stage from seed to seedling, while in clonal propagation it appeared during the period from an asexual plantlet to a ramet.
      
Clonal seedlings showed a great advantage in the initial stages, but this advantage disappeared after 15 years.
      
With all the above techniques, 48 hm2 of clonal forests for pulp use of those clones had been planted in five places in Fujian Province.
      
Variation analysis and fine family selection on half-sib progenies from clonal seed orchard of Pinus massoniana
      
Variation of traits that include height, diameter at breast height (DBH), stem volume, crown width, straightness, wood basic density, tracheid length and width of open-pollinated progenies from clonal seed orchard of Pinus massoniana was analyzed.
      
canadensis reproduces asexually via underground rhizomes and nodes on the stem base to recruit new individuals, and in plants that experience mechanical damage, this reproductive strategy is used to produce clonal shoots.
      
Asexual and sexual reproductive strategies in clonal plants
      
Extensive clonal growth may affect the evolution of life history traits in many ways.
      
First, in some clonal species, sexual reproduction and sex ratio vary largely among populations.
      
Second, clonal growth can increase floral display, and thus pollinator attraction, while it may impose serious constraints and evolutionary challenges on plants through geitonogamy that may strongly influence pollen dispersal.
      
Some co-evolutionary interactions, therefore, may exist between the spatial structure and the mating behavior of clonal plants.
      
Finally, a trade-off may exist between sexual reproduction and clonal growth.
      
Future studies should investigate the reproductive strategies of clonal plants simultaneously from both sexual and asexual perspectives.
      
Responses of Hedysarum Laeve, a guerrilla clonal semi-shrub in the Mu Us sandland, to local sand burial
      
Arid and semi-arid inland deserts are frequently colonized and stabilized by many rhizomatous clonal plants.
      
Clonal physiological integration often helps clonal plants buffer local environmental stress encountered by ramets.
