Is ploidy status related to growth form? Insights from the alien flora of Kashmir Himalaya
Whether ploidy status of plant species is related to their growth form is not well supported by quantitative data despite having been speculated a lot. Deciphering this relationship has implications for management of alien invasive species as well as conservation of rare endemics. Hence, we tested the relationship between ploidy status and growth form in 390 alien plant species. Ploidy data was obtained through standard...
