将番茄和石刁柏种子放置在-0.8Mpa 下的聚乙二醇8000(PEG)、人工海水(INO)或 C_a~(+2),K~+,N_a~+与 Cl~-,NO_3~-,H_2PO_4~-,SO_4~(-2)的组合液中促发一星期(20℃,无光照),然后移入20℃的0.5倍 Hoagland溶液中发芽。促发处理并不影响番茄种子的发芽率,但使石刁柏种子的发芽率从未经处理时的85%提高到90%。所有的促发处理都缩短了这两种作物50%发芽率(G_(50))的时间,但仅缩短了番茄种子10%～90%发
The seeds of tomato and Asparagus were placed in polyethylene glycol 8000 (PEG), artificial sea water (INO) or C_a ~ (+2), K ~ +, N_a ~ + and Cl ~ -, NO_3 ~ -, H_2PO_4 ~ -, SO_4 ~ (-2) for one week (20 ℃, no light), and then moved to 20 ℃ 0.5 times Hoagland solution germination. The germination rate did not affect the germination rate of tomato seeds, but the germination rate of asparagus seeds increased from 85% to 90% when untreated. All of these treatments shortened the 50% germination (G_ (50)) time for both crops, but only shortened 10% to 90% of tomato seeds
