摘要: 研究了超干含水量、贮存温度对番茄种子生活力和活力的影响, 结果表明: 含水量为4. 6 %、
2. 4 %的番茄种子在20 ℃下密封贮存13 年后, 发芽率、苗长、脱氢酶活性、SOD 活性与对照(0 ℃、6. 2 %)相比均无明显差异, 但含水量为1. 9 %的种子上述指标却显著下降, 说明含水量为4. 6 %、2. 4 %的超干番茄种子在常温下具有良好的耐藏性, 含水量过低(1. 9 %) 不利于长期贮存, 但上述三种含水量(4. 6 %、2. 4 %、1. 9 %) 的番茄种子在0 ℃下密封贮存13 年后, 均有着较高的种子活力、生活力和酶活性。

Abstract: The effects of different moisture content on viability and vigor of tomato seeds were studied. At the MC of 4. 6 % and 2. 4 % , there was no injury to tomato seed after 13 years storage at 20 ℃, it did not vary
significantly either in seed viability or seed vigor , the activities of dehydrogenase and SOD also remained well , electric conductivity value indicated that the membrane system of this treatment had good integrity , while at 1. 9 % moisture content , all those indexes decreased significantly. Those ultra2dried tomato seeds remained relatively high seed viability and vigor after 13 years storage at 0 ℃. The results indicated that we can store germplasm of tomato by using suitable ultradry storage.

Key words: Tomato, Seed, Ultra2dry, Storage, Viability, Vigor
