SEED TESTING EQUIPMENT’S SEED A seed is an embryonic plant enclosed in a protective outer covering with small quantity of food storage. SEED TESTING Seed testing is a determining the standards of a seed ,physical purity ,moisture, germination and therby enabling the farming community to get quality seed. IMPORTANCE OF SEED TESTING • The importance of seed testing was realized more than 100 years ago for assured planting values. The adulteration of vegetable seeds by stone dust which was packed in some parts of the world • Seed testing has been developed to aid agriculture to avoid some of the hazards of crop production by furnishing the needed information about different quality attributes viz., purity, moisture, germination, vigour and health. • Quality control of seed depends on the different seed testing protocols which determine the genuineness of the cultivar. • Testing of seed to evaluate the planting value and the authenticity of the certified lot. • Seed testing is required to assess the seed quality attributes of the seed lots which have to be offered for sale. 1.SEED SAMPLING AND DIVIDING EQUIPMENT BOERNER DIVIDER This divider is made to meet F.C.I and B.I.S. Requirements. Material flowing components are made by special process to give smooth finish and made without welding or joint. It is used to reduce the size of grain/seed sample into two halves, each exactly representative of the original sample. GAMET DIVIDER This divider is made to meet F.C.I and B.I.S. Requirements. Material flowing components are made by special process to give smooth finish and made without welding or joint. It is used to reduce the size of grain/seed sample into two halves, each exactly representative of the original sample. SOIL TYPE DIVIDER It is suitable for dividing or halving dry materials. Materials poured into hopper is divided into two equal divisions and discharged alternatively in opposite directions into separate pans. 2. SAMPLE STORAGE BOXES AND RACKS A box for storing seeds until they are ready for planting. A box for growing seeds till they are ready to be transplanted. 3. BALANCE – SINGLE PAN,ANALYTICAL BALANCE In this type of balance the pan and weights are counterbalanced by a single fixed weight on the long end of the beam. an analytical balance is a class of balance designed to measure small mass in the sub milligram range .The measuring pan of an analytical balance is inside a transparent enclosure with doors so that dust doesnot collect and so any air currents in the room do not affect the balance operation. 4. PURITY WORK BOARDS t is used for testing physical purity of seed samples with maximum comfort and efficiency. Also used to distinguish discolored, damaged and chalky grains/ seeds. Light below the rectangular 8” x 6” opal glass makes a handy diaphanoscope. 5. GERMINATORS –CABINET GERMINATORS AND WALK IN R ROOM GERMINATORS Seed Germinators and Seed walk-in rooms are designed to use in performing seedling process in laboratories. A seed germination machine provides controlled environment for propagation of seeds, incubation, seed germination and development tests. In this equipment, temperature, relative humidity and light are managed to create essential conditions responsible for adequate seeding. 6. REFRIGERATOR Not all applications are the same—that’s why we offer three series of Thermo Scientific biomedical laboratory refrigerators. Each series offers unique features and benefits while utilizing different cooling technologies that are best suited for your applications. Our laboratory-grade refrigerators offer key differences from domestic, retail, or catering storage units, including microprocessor-controlled setpoints, alarms, time- and temperature-sensitive auto-defrost systems, temperature monitoring and recording, and electrical output signals.
