2008 Annual Report
The most significant accomplishment in the past year was the completion of data collection for our evaluations of the genera allied with Citrus, the ‘citrus relatives’. The approximately 600 trees of the different relative taxa in the subfamily Aurantiodeae in the Rutaceae in the collection were evaluated for 80 different descriptors such as growth habit, spine length, lamina shape and width, flower arrangement and color, length of anthers, time of flowering and fruiting, fruit weight and shape, oil gland size, pulp texture, vesicle length, seed weight, and seed embryology. The project was divided into three parts: vegetative characteristics, flower characteristics, and fruit/seed characteristics. Characterization of the 20 different leaf and tree descriptor was completed first, then the fruiting and flowering times for each accession in each location. The documentation of fruiting and flowering times is not only part of the descriptor data, but is also essential in determining when the most appropriate time is for gathering flowers and/or fruit in future collections for characterization. An excel file has been developed to enable uploading the information to the GRIN database. ADODR monitored activities by meetings and site visits.
