Hydrocarbons associated with the developing microspores in the anther loculus of Tulipa cv. Apeldoorn were investigated. They occurred mainly at chain lengths between C 19 and C 29 . At the lower chain lengths the n‐alkanes, at higher chain lengths the alkenes dominated. During microspore development the ratio of unsaturated to saturated hydrocarbons in the extracts changed. While the content of all main hydrocarbons increased, the content of the alkanes C 19 , C 21 and C 23 increased to 3.8, 3.4 and 3.3 times the initial value compared to 2.1, 2.0 and 2.2 times in case of the alkenes C 25 , C 27 and C 29 . Surface lipids from petals, leaves and ripe pollen were analyzed in comparison and these analyses confirmed that a high amount of alkenes was unique for microspores. Iso‐heptacosane was the main hydrocarbon from ripe pollen, heptacosene was a main component when microspore extracts were analyzed.
