Product specification
Please see the table on the next page for our seed quality specifications.
ESA PRODUCT SPECIFICATIONS These product specifications for germination of precision seeds, varietal purity of precision seeds and seed health requirements are based upon ESA recommended standards.
These product specifications are notmeant to be absolute minimumstandards for delivery. If the quality tests of Elsoms indicate a lower quality level than given in these specifications, Elsoms will informperspective seed users. This communication is aimed at informing professional seed users about the quality they can expect, so they canmake their own assessment and decide if these seedsmeet their requirements.
GENERAL DEFINITIONS Germination Germination tests relate to ISTA procedures and are valid at the time of despatch.Our licensed satellite seed testing station is used to test seed before and after treatment, and germination checks are carried out according to ISTA testmethods and guidelines by our qualified analysts.
• Normal seed: In general, normal seed has not been subjected to special processes. It is sold by weight and/ or by count depending on the product. Normal seed complies with EC Standards.
• Precision seed: Precision seed has been subjected to additional processes. It has a uniformsize and high germination. Precision seed is sold by count.
Reaction of plants to pests or pathogens According to: International Seed Federation (ISF), Section Vegetables. (Adopted 28.05.04 Berlin)
A Immunity: Not subject to attack or infection by a specified pest or pathogen.
B Resistance is the ability of a plant variety to restrict the growth and development of a specified pest or pathogen and/or the damage they cause when compared to susceptible plant varieties under similar environmental conditions and pest or pathogen pressure. Resistant varietiesmay exhibit some disease symptoms or damage under heavy pest or pathogen pressure. Two levels of resistance are defined.
P denotes seed available for trial purposes only’
High/standard resistance (HR): plant varieties that highly restrict the growth and development of the specified pest or pathogen under normal pest or pathogen pressure when compared to susceptible varieties. These
plant varietiesmay, however, exhibit some symptoms or damage under heavy pest or pathogen pressure.
Moderate/intermediate resistance (IR): plant varieties that restrict the growth and development of the specified pest or pathogen, butmay exhibit a greater range of symptoms or damage compared to resistant plant varieties. Moderately/intermediately resistant plant varieties will still show less severe symptoms or damage than susceptible plants varieties when grown under similar environmental conditions and/or pest or pathogen pressure. (These standard abbreviations HR (high/standard resistance) and IR (moderate/intermediate resistance) are used throughout the text.)
C Susceptibility is the inability of a plant variety to restrict the growth and development of a specified pest or pathogen.
