Representatives of the Crambe L. genus are interesting objects among other Brassicaceae
Burnett due to different biological activities. Fruits of these species are rich in oil, which
contains more than 54 % of erucic acid that has many applications in the chemical, cosmetic,
and food industries. They are promising as fodder, food, decorative and medicinal plant. Species
of this genus exhibited different biological activities such as antioxidant and antimicrobial.
One of the important aspects of the introduction study is morphometric parameters of
different organs including fruits. Investigated plants have false two-nested two-membered
pods. The period of fruitage can last from July to September depending on the species. The
investigation was conducted on perennial plants.
Fruits of the following Crambe species were used for this study: C. cordifolia Steven (CC),
C. hispanica subsp. abissinica (Hochst. et R.E.Fr.) Prina (CH), C. koktebelica (Junge) N.Busch (CK),
C. maritima L. (CM), C. steveniana Rupr. (CS). Raw was collected in 2017–2020 from
experimental collections of M.M. Gryshko National Botanical Garden of the NAS of Ukraine for
measuring of length of flower (mm), the diameter of flower (mm), length of the petal (mm), a
width of the petal (mm); fruit length (mm), fruit width (mm), fruit diameter (mm). Weight of
fruits given in grams.
The measuring of flower length and diameter of investigated species was 5.03–16.46 mm
and 0.23–0.55 mm, respectively. The petal length and width were 3.63–6.56 mm and 3.61–5.51
mm, respectively. The most variable parameters were the diameter of the flower (CM) and the
length of the petal (CM). The less variable sign was the length of a flower of CS. Fruit length was
3.02 mm(CH), 3.20 mm (CC), 4.11 mm (CK), 5.36 mm (CS), and 10.14 mm (CM). The fruit width
was measured as 2.33 mm for CC, 3.16 mm for CH, 4.05 mm for CK, 4.73 mm for CS, and 9.96
mm for CM. Fruit diameter was 3.41 mm (CH), 4.08 mm (CC), 4.30 mm (CK), 5.58 mm (CS), and
8.78 mm (CM). Also, the thousand-fruit weight of investigated Crambe species was 7.34 g (CC),
8.51 g (CH), 8.77 g (CK), 11.12 g (CS), and 12.54 g (CM). The most variable morphometric
parameter was fruit width for CK (11.79 %), CM(18.72 %), CC (21.04 %), CS (22.54 %), and
fruit length for CH (15.75 %). The study of all investigated parameters showed a very strong
correlation between each other. Between length and diameter of fruits, a correlation was 0.993,
length and width of fruits 0.990, width and diameter of fruits 0.968, and connection of rest
parameters was in range 0.900–0.905.
The study of morphometric parameters of flowers and fruits of Crambe growing in M.M.
Gryshko National Botanical Garden can be useful for further selective work with this species as
potential food, forage, energetic, etc. plants.
Keywords: Crambe, flower and fruits morphometric parameters.
