VEGETABLE SEED 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. Vegetable growing has become a highly specialized and intensive activity. As a result of the ever increasing demand for better quality, vegetable growers and plant raisers require an improved quality of the basic material.
The demand for specific seed forms and more information about seed quality has strongly increased to better influence emergence and required number of plants.
Seed is a natural product. The often varying environmental conditions thus influence final results. It is therefore often not possible to give detailed information about emergence and other physical seed characteristics. To meet the wishes of clients as much as possible HM.CLAUSE has made up quality standards for the various seed categories.
The germination percentages mentioned are HM.CLAUSE minimum required figures and made up according to ISTA* methods and tolerances.
GENERAL DEFINITIONS 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 uniform size and high germination. Precision seed is sold by count.
PRIMING Priming : is defined as an activation of the germination process with the purpose to obtain faster or more uniform emergence after sowing. Primed seed is sold by count.
PELLETING Pelleting is defined as the process of changing the seed form by covering it with a material, the main purpose being to improve uniformity of size and shape resulting in improved sowing ability. Also additional ingredients may be added. Pelleted seed is sold by count.
FILM COATING Film coating is a full covering, usually pigmented layer, around the seed. The original seed form remains intact. Additional ingredients may be added. Film coating treat- ments that contain insecticides are normally identifiable by colour coding. Film coated seed is sold by count.
GLUE COATING Glue coating is a process which fixes the applied crop protection products in an almost dust free manner to the seed. A pigment may be added.
GERMINATION Germination figures relate to ISTA* procedures and are valid at the time of despatch.
VARIETAL PURITY Rate is defined as the percentage of plants from a seed lot that meets the variety description.

ESA RECOMMENDATION ON SEED HEALTH REQUIREMENTS
In order to supply sufficiently healthy vegetable seeds and in order to meet the requirements of EU Council Directive 2002/55/EC, HM.CLAUSE uses various disease risk management strategies to prevent and control seed transmitted diseases. These may include and are not limited to seed health testing programs, protected seed production, field inspections, seed treatments and other effective seed disinfection methods.
ISHI-VEG has developed the Manual of Seed Health Testing Methods, which includes state of the art seed health testing protocols. HM.CLAUSE follows the ISHI- VEG recommended minimum sizes of a representative sample for seed health testing.
Information regarding the ISHI-VEG seed health test protocols and recommended minimum sample sizes can be found at: http://www.worldseed.org/isf/ishi_ vegetable.html
DEFINITION OF THE TERMS DESCRIBING THE REACTION OF PLANTS TO PESTS AND PATHOGENS
Susceptibility is the inability of a plant variety to restrict the growth and/or development of a specified pest.
Resistance is the ability of a plant variety to restrict the growth and/or development of a specified pest and/or the damage it causes when compared to susceptible plant varieties under similar environmental conditions and pest pressure.
Resistant varieties may exhibit some disease symptoms or damage under heavy pest pressure.
Two levels of resistance are defined.
HIGH RESISTANCE (HR) :
Plant varieties that highly restrict the growth and/or development of the specified pest and/or the damage it causes under normal pest pressure when compared to susceptible varieties. These plant varieties may, however, exhibit some symptoms or damage under heavy pest pressure.
INTERMEDIATE RESISTANCE (IR): :
Plant varieties that restrict the growth and/or development of the specified pest and/or the damage it causes but may exhibit a greater range of symptoms or damage compared to high resistant varieties. Intermediate resistant plant varieties will still show less severe symptoms or damage than susceptible plant varieties when grown under similar environmental conditions and/or pest pressure.
Varieties claiming the same level of resistance against a specific pest may exhibit a different resistance response due to a different genetic makeup of a variety.
It is to be noted that if a resistance is claimed in a plant variety it is limited to the specified biotypes, pathotypes, races or strains of the pest.
If no biotypes, pathotypes, races or strains are specified in the resistance claim for the variety, it is because no generally accepted classification of the cited pest by biotype, pathotype, race or strain exists. In this case resistance is only claimed against certain not further specified isolates of that pathogen. New biotypes, pathotypes, races or strains that may emerge are not covered by the original resistance claim.
Immunity is when a plant is not subject to attack or infection by a specified pest.
