摘　　要：大样本采集新疆野核桃自然保护区野核桃种子全部14个变型和迁地移栽野核桃2个变型,分析种子的生物量可塑性,建立种子构件间的生长模型。结果表明,野核桃大多数种子的壳重、仁重、膜重和总重在不同野核桃变型间差异显著。种子壳重以铁壳、尖嘴、矩圆、心形、卵圆、歪嘴、典型、三棱、纺锤、尖果、小圆、薄壳、长薄壳、小矩圆顺序减小;仁重以铁壳、矩圆、尖嘴、心形、典型、薄壳、卵圆、歪嘴、三棱、尖果、小圆、纺锤、小矩圆、长薄壳顺序减小;膜重以尖嘴最大,纺锤最小。单果重以铁壳、矩圆、尖嘴、心形、典型、卵圆、歪嘴、三棱、尖果、小圆、纺锤、薄壳、小矩圆、长薄壳顺序减小。种仁比率为43.33%—47.28%,以小矩圆、典型、(薄壳=卵圆)、长薄壳、矩圆、歪嘴、心形、尖嘴、三棱、小圆、尖果、铁壳、纺锤顺序减小。种子总重与壳重、总重与仁重的生长关系分别可用直线、乘幂、指数和对数方程定量描述,大部分为异速生长型,各构件在种子不同生长期的增长快慢可通过各方程的性质反映。新疆野核桃在迁地移栽后有更大的种子。All the 14 variants of wild walnut seeds and two variants of the relocated transplanting wild walnut seeds in the Wild Walnut Nature Reserve in Xinjiang were collected, with their biomass plasticity being analyzed, and their components growth pattern being established. The result showed that the seed shell weight, kernel weight, membrane weight and fruit weight of different variants of wild walnuts were significantly different. The shell weight ranked as J.cat.f.scl., J.cat.f.ros., J.cat.f.obo., J.cat.f.car., J.cat.f.ova., J.cat.f.obl., J.cat.f.cat., J.cat.f.tri., J.cat.f.fus., J.cat.f.bre., J.cat.f.mic., J.cat.f.lep., J.cat.f.dur., and J.cat.f.mib. in descending orders, and the kernel weight ranked as J.cat.f.scl., J.cat.f.obo., J.cat.f.ros., J.cat.f.car., J.cat.f.cat., J.cat.f.lep., J.cat.f.ova., J.cat.f.obl., J.cat.f.tri., J.cat.f.bre., J.cat.f.mic., J.cat.f.fus., J.cat.f.mib., and J.cat.f.dur. in descending orders. The J.cat.f.ros. had the maximum membrane weight, while the J.cat.f.fus. had the minimum membrane weight. The weight ranked as J.cat.f.scl., J.cat.f.obo., J.cat.f.ros., J.cat.f.car., J.cat.f.cat., J.cat.f.ova., J.cat.f.obl., J.cat.f.tri., J.cat.f.bre., J.cat.f.mic., J.cat.f.fus., J.cat.f.lep., J.cat.f.mib., and J.cat.f.dur. in descending orders. The specific weight of kernel of seeds 43.33%-47.28%, the ratios ranked as J.cat.f.mib., J.cat.f.cat.,（J.cat.f.lep.=J.cat.f.ova.）, J.cat.f.dur., J.cat.f.obo., J.cat.f.obl., J.cat.f.car., J.cat.f.ros., J.cat.f.tri., J.cat.f.mic., J.cat.f.bre., J.cat.f.scl., and J.cat.f.fus. in descending orders. The relationships between seed total weight and shell weight, seed total weight and kernel weight respectively fitted linear equation, exponentiation equation, exponential equation and logarithmic equation; most of growth relationships were allometric type. The growth rate of the seed component at different growth stages could also be reflected by the equations mentioned-above. The wild walnut after relocated transplanting had larger seeds.
