3. Results and discussion
3.1. Effect of processing on mechanical damage
The damage to the seed increased by2.9% (on average) in the vertical bucket elevator (Table 2).
The reason for this maybe that the seed layer receives impact when the elevator cups lift it and
again when the seed is discharged at the delivery end under centrifugal force. In addition, the freefall of seed on to the pan of the grader causes damage. The damage, which was 18%, was observed in the form of splits or seed coat cracks. The air-screen cleaner removed the split and damaged seeds and therefore, only a loss of 2% was noticed after size grading. Losses below 1% were observed after gravity separation. The m:c: had a significant effect on the physical damage
sustained. The seed lots at 12% m:c: suffered less mechanical damage than the lots at 10% and
11% m:c:
3. 结果以及讨论
3.1. 机械性损伤的操作影响
在垂直的链斗升降机当中对豆种造成的损坏为2.9%（平均）。造成这个的原因可能是当升降机斗升起的时候， 豆层之间有相互的撞击， 当倒出他们的时候， 在地心引力的作用下，它们再一次受到冲击。另外， 豆种自由下落倒分级机的板上也会受到破坏。 18%的破坏是从豆裂以及豆皮的破损观察出的。空气过滤机把裂开的，损坏的豆种滤掉， 因此， 在按粒度分级之后，人们只注意到2%的损失。还有不到1%的损失是在经过重力分级机之后发现的。含水量在连续的物理性破坏之后受到巨大的影响。 在含水量在12%的种子比含水量在10%和11%的种子受到的机械性破坏要少。

3.2. Effect of processing on seed germination
There was significant loss in germination when the vertical bucket elevator lifted the seed
(Table 3). The air-screen cleaner improved the average germination of seed lots by1.8%. It also
removed other impurities like shriveled seed, undersized seed, and splits during processing. The
air-screen cleaner and gravity separator both significantly improved the germination rate of the remaining seed by removing damaged seeds. Similar results have been reported by Misra et al.
(1985). The m:c: had significant effects on germination of seed lots. The seed lots with 12% m:c: lost an average of 3% germination while the seed lots with 10% m:c: lost an average of 5% germination.
3.2. 工序在种子发芽方面的影响。
当垂直的链斗升降机把种子提起来的时候，会对种子的发芽率产生重要的影响（见表3）。空气过滤机提高了种子的平均发芽率1.8%。而且它在工序当中还能过滤其它的比如枯萎的种子，没发育好的种子和裂开的种子。空气过滤机和重力分级机都能很显著的通过剔除受损坏的种子来保持种子的发芽率。Misra在1985年就报道过类似的结果。含水量对种子的发芽率有着很重要的影响。 含水量在12%的种子平均在发芽率上只有3%的损失， 而含水量在10%的种子在发芽率上却有5%的损失。

3.3. Effect of processing on the vigor index of the seed
The vigor index of the seed dropped significantly after the elevating stage (Table 4). The seed at
12% m:c: showed a higher vigor index than that of lower m:c: Similar to germination, the vigor of the seed improved significantly after size grading. The loss in vigor occurred mainly in the first stage of handling where maximum mechanical damage had taken place.
3.4. Effect on storage as measured by accelerated aging test
The germination of the untreated seed lots, after the accelerated aging test, was 72% (average) and the germination did not decline after size and gravity grading (Table 5). The accelerated aging test showed that the lots at 12% m:c: maintained higher germination than the lots processed at 10% and 11% m:c: The lots at 10% m:c: suffered maximum damage during processing which reflected their poor storage quality。

3.3 工序在种子活力指数方面的影响。
种子的活力指数在经过链斗升降那步后会有很打的下降（见表4）。 含水量在12%的种子相比含水量低的种子，表现出更好的活力指数。发芽率也是一样， 种子的活力指数在经过粒度分级后得到很大的提升。种子活力损失主要是在是发生在收到最大机械性损伤的第一步。
3.4 通过加速老化试验显示的储藏方面的影响。
没有处理过的一批种子的发芽率， 在经过加速老化试验之后，显示72%（平均），并且在经过粒度分级以及重力分级之后并没有下降（见表5）。 加速老化试验显示，含水量在12%的种子的发芽率比经过处理的含水量在10%和11%的种子更高，这批含水量在10%的种子在加工过程中经历了最大的损坏， 也反映出了他们很差的储藏质量。
