Introduction,y. But progress has been made : more fragments exist and some of them begin to tell a story. The main purpose of this book is to pick out the more significant of these and attempt to interpret them; and it is the main task of this chapter to survey the relevance of viability studies and to act as a guide to the book as a whole.作者: Mettle 時間: 2025-3-25 06:13
Loss of Viability and Crop Yields,djustment may be greater than that indicated by a simple germination test, since the decreased vigour of the surviving seedlings (various aspects of which have been discussed in Chapters 4, 6, 7 and 8) may well result in a lower field emergence than can be obtained from fresh seed.作者: 貝雷帽 時間: 2025-3-25 10:05 作者: 煤渣 時間: 2025-3-25 13:07
