In the grass family the seed or fruit is called a grain or caryopsis, in the buckwheat and sunflower families an achene, and in the mint family a nutlet. … If SEED SAVING is collecting seeds for replanting in the future… Then SEED STEWARDSHIP is the process of saving seeds with the purpose of maintaining or improving that seed’s health and resilience. In this chapter we will discuss the structure and development of seeds and fruits and their adaptations for dispersal. In any seed lot, losses of seed vigour are related to a reduction in the ability of seeds to carry out all the physiological functions that allow %%EOF speaking, rather than true seeds. The seed coat consists of one or more protective layers that encase the seed. Spread and level the seeds on a palm mat, plastic sheet, bright-colored plastic sheet (a dark-colored plastic sheet will accumulate too much heat for the seed), or winnowing basket, then choose a location where there is sun for the whole day. It is important in this respect to establish the probability of accepting a seed lot with disease incidence higher than the tolerable disease level, and the probability of rejecting a seed lot … 4. @1��b���T����e�qL`t����E�ܒh���l鬃9#$#6E��*�� Ђ���b� w�{���V���?�Qv���x�F��/�Ȇվf����%n?NHl8�!�!��2z�F7�!�!^h६ �Ɖ�HH2 a8yϫ����u��O�4,,j��#ƨN���i��#k�I�\�8��e��*/3��ghƍb�=�tIWi�E�"��6�6y�;�����è���-��n��l���x� a��/8��~�+BBzo��I�,��^# vj;x�֛n xB�̀��@�0�P��͍����?��}���'f���F�=�eqQ]�JH�M��:��9�̱��&�b40$�u�GÅ��0ZE}�A�?�)��K�p��)��1t���p� $�4�r��T�FC�O�D��eh� l^�}��p�� b��7�9�^دȇp=b�<��\��D�9�vXG��e�Ƶ�mm��*z� �S1щ��Py�G�v �Ilț�q�S�(���q��!5aħ���v�� Seed Analysts and define the areas within which they shall exercise jurisdiction.
