Table 1. Sampling goals, work stages and summary of data collected.
Sampling goalPhenology of flowering and bulbils and production of basal shootsEstimation of bulbil production*Estimation of shoot production from rhizomesEstimation of rooting rates of bulbils under natural conditionsEstimation of the rooting rates of bulbils in experimental plots (greenhouse and natural conditions)*Phenology of shoots production and rate of establishment of new individuals (rooted bulbils vs shoots from rhizomes)Sampling unit60 individuals (30 from Agave fourcroydes and 30 from | A. sisalana)60 individuals (30 from Agave fourcroydes and 30 from A. sisalana)8 individuals (4 from Agave fourcroydes, 4 from A. sisalana)1,184 bulbils (582 from Agave fourcroydes, 602 from A. sisalana; 590 from early fall, 594 from late fall)1,440 bulbils, 24 from each of 60 individuals (30 from Agave fourcroydes, and 30 from A. sisalana)10 plots 10 × 10 mMonitored individual natureReproductive individuals with incipient floral scapes emerging from the rosetteReproductive individuals with floral scapes at the stage of maximum bulbils productionJuvenile, i.e., prominent but not reproductive individualsMature bulbils fallen from the floral scapesMature bulbils fallen from the floral scapesNew young individualsTraits measuredHeight andHeight andNumber ofHeight (cm)Height (cm)Origin: fromdiameter of the rosette (cm) Height anddiameter of the rosette (cm) Height andrhizomes Number of emerged shootsDiameter (cm) Number of leavesDiameter (cm) Number of leavesrhizomes or rooted bulbils Presence ofdiameter of the floral scape (cm)diameter of the floral scape (cm)from rhizomesNumber of preformed rootsNumber of preformed rootscontractile rootsNumber of scape branchesNumber of bulbils by scape branchesPosition (vertical or horizontal)Rooted% of branches with floral budsNumber of fallen bulbilsBuried or not% of branches with flowersRooted% of branches with bulbils% of branches with fruits% of branches with fallen bulbilsNumber of basal shoots (born directly from the rosette)Monitoring dates and frequencyFebruary 2015– May 2016 (monthly)October 2015May–July 2015October 2015– October 2016 (monthly)January 2016– May 2016February 2015– February 2016 (monthly)
