and orthodox seeds lie only on the maturity stage in which they are detached from the mother plant, the recalcitrant ones in a very immature stage. This implies that little progress should be expected to expand the storability of these recalcitrant... Desiccation sensitivity in orthodox and recalcitrant seeds in relation to development. This chapter discusses some of the mechanisms underlying desiccation tolerance of seeds and recent approaches to elucidate the precise roles of protective molecules and repair …

Orthodox seeds are seeds which will survive drying and/or freezing during ex-situ conservation. According to information from the U.S. Department of Agriculture, there is variation in the ability of orthodox seeds to withstand drying and storage, with some seeds being more sensitive than others.

SEED STORAGE BEHAVIOUR A COMPENDIUM
In the present report, TBARS was assayed as recalcitrant Spartina alterniflora and orthodox S. pectinata seeds were dried rapidly. Using the traditional Heath and Packer (1968) protocol with tissue extraction at 4°C, S. alterniflora had higher overall TBARS values than S. pectinata , and TBARS products increased when recalcitrant S. alterniflora and orthodox S. pectinata seeds were dried. hydraulic system components and their functions pdf The study aimed to determine the germination pattern of dicot and monocot seedling, break dormancy of ipil-ipil seeds (Leucaenaleucocephala L. and study the storage of orthodox seeds and recalcitrant seeds. The specific objectives were to determine and compare the germination pattern of a dicot and monocot seed corresponding to hypogeal and epigeal germination, determine the efficiency of.

  • Protective proteins might be involved in preventing damage during desiccation in orthodox seeds and might assist in repair mechanisms after desiccation in recalcitrant seeds, but it is difficult to conclude that those proteins clearly define differences between the seed categories.
  • In essence, seed storage behaviour refers to the capacity of seeds to survive desiccation. The classification used here largely follows that used in the hard copy Compendium of Information on Seed Storage Behaviour by T.D. Hong, S.H. Linington and R.H. Ellis, published in a limited run in 1998 by RBG Kew — ISBN 1 900347 49 0.
  • The definition of recalcitrant and orthodox seeds was coined in the early 1970s by Roberts [10]. He described recalcitrant seeds are those that are shed with high water content and active metabolism (they deteriorate upon dehydration) and cannot be stored for long periods of time. In contrast, orthodox seeds, which are the focus of the present review, are those that tolerate desiccation and
