Rehygdration-Dehydration And Magnetism Treatment Improve Vigor Of The Masson Pube Seed

This article adopts two methods of rehygdration-dehydration and magnetism treatment and come to pretreat different masson pine seed of germination percentage, Studying its improvement of sowing quality to the masson pine seed, the results of the test shows :1. Adopt rehygdration-dehydration and deal with germination percentage as 66% masson pine seed, adopting 30℃ constant temperature of dry, and two and three circulations(under 10℃condition) have better results, improve masson pine germination percentage of seed obviously, improved by 17% and 14% separately. Sprout tendency, germination index rises notably even equally at the same time.2. Pick up rehygdration-dehydration and deal with germination percentage as 66% masson pine seed, adopting naturally dry, under 10 ℃ terms of on temperature masson pine germination percentage of seed have obvious influence One, two and three circulations have been improved by 16%, 17% and 10% respectively, under 20 ℃ terms, two circulations treatment germination percentage rises notably compared with contrast, Other two treatments masson pine seed germination percentage have no change , sprout time two circulation dealing with is shorten 2 days equally.3. Pick up rehygdration-dehydration and deal with germination percentage have no effect on germination percentage for 83% high vigor masson pine seed, but to time of sprouting equally, sprout tendency and germination index obviously influences , Especially sprout tendency and germination index raise remarkable, sprout tendency by 40% - 72%, germination index by 10.84% - 30.26%.4. In different temperature, pick up rehygdration-dehydration and deal with masson pine seed, three treatment methods raise activation of peroxide enzyme.Three circulations(under 10 ℃ condition) germination percentage raise for 66% masson pine seed peroxide enzyme activation most higho5. Pick up rehygdration-dehydration and deal with different masson pine seed of vigor, different temperature and different treatment methods improve activation of CAT obviously .6. Picks up rehygdration-dehydration and deal with different masson pine seed of vigor, most of different temperature and different treatment methods improve activation of SOD 7. Magnetism deal with high masson pine seed of vigor can not improve their germination percentage ,but can improve sprout tendency of masson pine seed , impel seeds to be sprouted rapidly, and emerge neatly8. In the same time, magnetic field deals with the germination percentage for 66% of the masson pine seeds, up to magnetic field increase of intensity, activation of POX presents the trend of rising; With germination percentage for 83% masson pine seed, up to magnetic field increase of intensity, activation of POX demonstrates too that there is the law that rises.9. under the same magnetic field intensity, magnetic field deals with germination percentage for 66% and 83% of masson pine seeds, With increase of time, peroxide enzyme activation presents the trend of rising.10. In the same magnetic field intensity, different time deal with germination percentage 83% of the masson pine seeds, activation of SOD up to increase of time drop in the form of ladder of time.11. With different magnetic field intensity dealing with germination percentage as 66% masson pine seed at the same time, activation of SOD is on the rise.
