| 摘 要： | 对美国山核桃Carya illinoensis种子分别进行了不同储藏时间、不同储藏方式和不同植物生长调节物质浸种,结合层积处理的种子发芽试验。结果表明：美国山核桃种子不宜即采即播,种子储藏在2个月以上用3~5℃冷库保存效果较好,随着储藏时间的推移,发芽率会降低;植物生长调节物质浸种和层积催芽可显著地提高美国山核桃种子的发芽率。层积催芽前最好用植物生长调节物质浸种8 d,然后在室内层积催芽35 d,发芽速度最快,田间发芽率可达91%。表6参20

| Abstract: | A germination test of Carya illinoinensis seeds was conducted with different storage times and methods as well as various soaking methods using phytohormones,and differing seed stratification procedures.Results showed that seeds of C.illinoinensis should not be sown immediately after harvest.For seeds stored for more than 2 months,a 3-5 ℃ cold storage was best;and as storage time increased,germination rate decreased.The germination rate improved remarkably with phytohormones and stratification.Among stratification methods,soaking the seeds in phytohormone for 8 d and then stratifying them indoors for 35 d,produced seed germination rates as high as 91%.Ch,6 tab.20 ref.] |
