Abstract: Key message Sunlight is a key environmental factor in growth, flowering and shaping of the Dracaena draco tree. Unidirectional light deforms the tree and may cause it to tilt. Abstract Dracaena draco, a tree-like monocot, lives in cycles of vegetative growth and flowering. The cycles, as well as the tree growth form, are under genetic control. What controls their length has been unknown before. We propose that it is sunlight. Our trees of the same origin, growing for 20 years in the garden in varying sunlight … Show more

“…The key factor determining the height of the trunk and the shape of the Dracaena crown is sunlight [75,76]. The regular umbrella-like crown is formed in full sunlight, but asymmetrical crown develops under the condition of unidirectional, oblique sunlight [70,76].…”

“…The key factor determining the height of the trunk and the shape of the Dracaena crown is sunlight [75,76]. The regular umbrella-like crown is formed in full sunlight, but asymmetrical crown develops under the condition of unidirectional, oblique sunlight [70,76]. Moreover, the branching of the dragon tree is correlated with flowering [76], but it could also be initiated by the decapitation of the main stem [77,78].…”

“…Branching of the trunk is correlated with flowering; thus, more than one equivalent axis is newly formed below the inflorescence which terminates the axis, and these subsequently repeat the construction of the parent axis (Symon 1974;Hallé et al 1978;Bos 1984). Thus, the dragon tree crown consists of repetitive units/modules that arise at long time intervals (Symon 1974;Krawczyszyn and Krawczyszyn 2016). Data relating to the time of flowering, followed by branching, are divergent.…”

“…For example, Symon (1974) noted that it occurs about every 10 years, while Byström (1960) reported that it can take place every 10-14 years. According to Krawczyszyn and Krawczyszyn (2016), the timing of flowering of a given branch is determined by the amount of sunlight it receives, with branches exposed to the sun flowering sooner than those subjected to shade. The orders of branching and frequency of flowering can be used as the basis for calculating the age of a dragon tree (Adolt and Pavlis 2004;Adolt et al 2012); the oldest representative of D. draco, which grows on Tenerife (Canary Islands), is estimated to be about 400 years old (Mägdefrau 1975).…”
