[Science News] – A comprehensive handbook for measurements of plant reproductive traits: from flowers to seedlings

Standardising sampling protocols is important to reliably compare scientific studies and to combine data from different studies. Handbooks providing protocols for standardised measurements of plant functional traits  -measurable biological characteristics that play a key role in the life cycle of plants - allow researchers to tackle large-scale ecological questions. Until now these protocols focused only on vegetative traits such as leaves, stems and roots. 

Meise Botanic Garden contributed to an extensive handbook that provides standardised protocols for relevant reproductive traits to better understand processes, such as pollination, frugivory, seed dispersal, seed longevity, germination, and seedling establishment. These protocols are based on 58 reproductive traits of flowers (10 traits), fruits (6 traits), seeds (36 traits), and seedlings (6 traits).

The protocols embrace the global diversity of ecological contexts experienced by flowers, fruits, seeds, and seedlings and incorporate methods for temperate to tropical, dry to moist, and fire-prone to fire-sensitive ecosystems. The handbook also offers general guidelines for sampling, storing, and processing reproductive traits. 

Besides the measurement protocols, the handbook also provides a brief description of the trait functions, trade-offs, and sources of variability. The illustrations in the handbook were made by a former internship student of Meise Botanic Garden.
