关于种子大小对作物生长的影响,在大田育苗方面已有广泛的研究(Kiesseib-ack,1924;Kautmann and Macfadden,1963;Harper and obeid 1967 and Gei-mond,1972).他们发现种子的大小与作物健壮生长有着密切的关系.但对于许多森林树种的研究尚处于初期阶段.然而,Suprr在1944年就报道了东方白松种子重量,与其发芽、生长和植株早期大小的关系.Griffir(1974年)发现用辐射松大粒种子播种育苗,其苗高比用小粒种子的苗大高18%,重大45%(以烘干重为准).
With regard to the effect of seed size on crop growth, extensive research has been conducted in the field of seedling development (Kiesseib-ack, 1924; Kautmann and Macfadden, 1963; Harper and obeid 1967 and Gei-mond, 1972) who found that seed size and crop However, Suprr reported on the weight of P. orientalis seed in 1944 in relation to its germination, growth and early plant size, and Griffir (1974) found that Larix radix seed sowing seedlings, the seedling height than the seedlings of small seedlings 18%, a significant 45% (to dry weight).
