# Morphometric data of individual seeds (N = 1200) of the Negorelskaya variety Pinus sylvestris L. (empirical dataset)

## Description

The dataset represents the results of direct measurements of the geometric dimensions (length, width and thickness in mm) and the mass in grams of each individual seed, as well as the calculated values of the projection area and the volume of the described ellipsoid based on these parameters. The dataset allows for correlation and regression analyses between geometric parameters and individual seed weight, and can also be linked to other datasets in the FLR-Library for the formation of summary queries.

## Steps to reproduce

For each seed from three sets (total number of seeds N = 1200), the dimensions, weight, area, volume of the ellipsoid were measured according to the methodology developed on the basis of and placed in transparent pockets under an individual number. The research methodology provided for the determination of the geometric char-acteristics of the seeds of the common pine variety "Negorelskaya", among which such parameters as the surface area of the seed (mm2) and the volume of the seed (mm3) were selected. The surface area of the seed was calculated using the formula of the area of the el-lipse, which most fully resembles the seed of the common pine in shape: Sс = π·L·W, где Sс – the surface area of the seed, mm2; π is a constant value equal to 3.14; L is the length of the seed, mm; W is the width of the seed, mm. The volume of the seed was calculated using the formula of the volume of an el-lipsoid, most closely resembling in shape and volume the seed of an Scots pine: Vс = 4/3·π·0,5L·0,5W·0,5T, где Vс – the volume of the seed, mm3; π is a constant value equal to 3.14; L is the length of the seed, mm; W is the width of the seed, mm; T is the thickness of the seed, mm.
