General information


Phenotype ID: ANN rm218P179
Name: Trichomes density leaf center flat are
Species: Helianthus annuus
Dataset: wild Helianthus annuus, SNPs remapped to HA412
Variation Type: continuous
Number of accessions: 596
Category: Leaf traits
Phenotype scoring: Density of trichomes outside secondary veins near the leaf main vein (trichomes/cm2)
Source: None
Description: A high resolution scan (2400 dpi) was taken for a 1.2 cm wide section of the abaxial side perpendicular to the leaf main vein, of the same leaf used for morphometric measurements. The number of non-glandular trichomes was determined in 1 cm2 region near the edge of the leaf and near the main vein. Trichomes on leaf surface or on secondary veins were counted separately using Fiji (Schneider et al., 2012; Schindelin et al., 2012).
