(1) Flowers unisexual or bisexual, apetalous.

(2) Apetalous property is very useful in rapeseed genetics and breeding.

(3) The discovery and study of apetalous sterility mutant in Brassica napus L.

(4) Brassica napus line Apet33-10 is an apetalous mutant which is controlled by one gene locus.

(5) Spadix rachis flat, margin with bract - like appendages; flowers small, monoecious, in 2 series on rachis, apetalous.

(6) The quantitative feature of 6 mangrove species of Sonneratia also indicates that the wood of S. caseolaria, apetalous sonneratia and ovate-...

(7) The genomic DNA PCR indicated that the genetic homogeneity between NIL-PL01 and NIL-APL01 reached 98.6%, which were being used in screening the molecular marker linked to apetalous trait.

(8) A perennial plant of the genus Sanguisorba, having pinnately compound leaves and apetalous flowers asgarnish.

(9) A tropical Asian perennial herb(Boehmeria nivea) having broad leaves and densely branched panicles of small, unisexual, apetalous flowers.

(10) In 1998, a sterile mutant plant was observed in apetalous lines in B. napus L, and an apetalous mutant sterile (AMS) line was established from this plant.

(11) The quantitative feature of 6 mangrove species of Sonneratia also indicates that the wood of S. caseolaria, apetalous sonneratia and ovate-leaf sonneratia is probably suitable for paper-making.

(12) Any of various plants of the genus Thalictrum, having compound leaves and clusters of small white, yellowish, or purplish apetalous flowers.

(13) A perennial plant of the genus Sanguisorba, having pinnately compound leaves and apetalous flowers. The young leaves are sometimes added to salads as a garnish.
