在国际种子贸易中杂交种子的纯度、发芽率、净度和含水量是四项主要质量指标。而在这四项质量指标中杂交纯度较为重要,一般要求在98%以上,为此我省在与国外多年合作制种的过程中突出抓了这一指标。至目前改进并普及了制种技术,所以在杂交纯度上基本有了保证。但在种子发芽率上由于国际种子行业上竞争激烈,其指标从85%提高到90%,所以出现了因发芽率达不到标准而不能出口的问题。我省生产的杂交番茄种子发芽率基本在98%以上,但是表中列出了经过大量测试得到的一些不合格批号。
The purity, germination rate, clarity and water content of hybrid seeds in the international seed trade are the four major quality indicators. In the four quality indicators of hybrid purity is more important, the general requirements of more than 98%, for which the province in cooperation with foreign countries for many years in the process of highlighting the catch this indicator. Up to now improve and popularize seed production technology, so the hybrid purity is basically guaranteed. However, the rate of seed germination due to fierce competition in the international seed industry, the index increased from 85% to 90%, so there is a problem because the germination rate can not reach the standard can not be exported. The germination rate of hybrid tomato seeds produced in our province is basically above 98%, but some unqualified batch numbers obtained after a large number of tests are listed in the table.
