Effects of seed priming on vigor of Prunella vulgaris seeds / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To select an effective way to enhance vigor of Prunella vulgaris seeds.</p><p><b>METHOD</b>Three population seeds were treated at the 20 degrees C and dark enviroment.</p><p><b>RESULT</b>Priming with 20% - 30% PEG and 200 - 400 mg x L(-1) GA3 could enhance seeds germination and vigor. Germination percentage of three population seeds treated with 0. 6% - 3.0% NaCl reduced, but they started to germinate in advance. Treated with 0.6% - 2.4% KNO3-KH2PO4, germination rate and vigor of seeds in Zijinshan and Pan' an both increased and the one in Bozhou decreased.</p><p><b>CONCLUSION</b>Vigor of P. vulgaris seed treated with PEG and GA3 under proper concentration increases, while treated with KNO3-KH2PO, and NaCl low vigor seeds germination rate reduces.</p>
