According to the year with the best large-seed production, the reasons for empty seeds could be estimated as follows: Seed potential per cone calculated as 2 times the number of fertile ovuliferous scales was about 206 seeds. Percentages of seed losses resulting from pre-and post-pollination ovule abortion, prezygotic factors, embryo degeneration, and efficient seed were 33%, 27%, 39%, and%, respectively.

依据大粒种子产率最高的1年来估测空粒种子产生的因素，可以推估如下：依据每个可孕性鳞片所含2粒种子的鳞片数，潜力种子数约有206粒，再依此值算出受粉前后胚珠败育率、受精前败育率、胚败育率、及有效种子率分别为33%、27%、39%及%。

Sclerophyllous garlic (up to 1000 kilograms per mu, garlic seed yield 400-500 kg) 2000-3000 mu yuan annual income; soft garlic leaves only the middle class did not produce seed garliccan be harvested, garlic seed, acres 900-1000 kg of seed garlic production,6000 kilograms per mu.

The inhibition substances in Sorbus pohuashanensisHedl fruit not only restrained the seeds of wheat, cabbage from germinating but also restrained height and root growth. After the seeds of wheat, chinese cabbage had been soaked in the water extraction of pulp, seed and decoated seed for 8h, the seed germination rates were 92% and 84%, 89% and 65%, 94% and 78%, lower than the control, especially the water extract of decoated seed; and the root length and seedlings height were lower than the control, especially the water extract of pulp, and decreased in sequence of soaking time from short to long. So the simplest and effective method to eliminate pulp soluble inhibiting substances is to wash fruits by flowing tap water soon after collection.

在几种浸泡时间中，浸泡8小时的去皮种子浸泡液对白菜、小麦种子发芽率的抑制作用最为明显，其发芽率分别为65%、89%，但随着浸泡时间的延长而降低；浸泡8h的果肉浸泡液对白菜和小麦幼苗高生长和根伸长的抑制作用最为明显，种子和去皮种子浸泡液(8h)的抑制作用对小麦和白菜的抑制作用次之，随着浸泡时间的延长，果肉浸泡液的抑制作用逐渐减弱，因而采收下来的果实及时净种是清除果肉水溶性抑制物质简单有效的方法。

The results showed that the sex ratio of trees was 1 m 2 f, and the natural T. cuspidata tree was able to sexually reproduce for many years. Male trees had fecundity when the diameter at breast height ranged from 1.5 cm to 92 cm, while female trees had fecundity when the DBH from 9.5 cm to 68.1 cm. Male trees typically flowered at the age about 20 years earlier than female trees. The numbers of microstrobili were 3 times more than that of megastrobili, and only 1/10 megastrobili developed into seed. The numbers of strobili and seed were correlated with DBH, crown diameter and height of trees; however, no significant correlations were observed with other site factors. Numbers of strobili decreased from the upper to lower canopy layers, while the quantity of seed decreased from the middle, upper to lower canopy layers. Seed-setting rate increased from the upper to lower canopy layers. Numbers of strobili and seeds in different directions of the canopy were not uniform, but the differences weren't significant.

结果表明：现实东北红豆杉天然种群中，♀♂性比为1：2；天然东北红豆杉有性生殖持续时间长，雄株胸径在1.5~92cm，雌株胸径在9.5~68.1cm保持生殖状态，雄株较雌株早约20年进入花期；天然东北红豆杉小孢子叶球数量平均为大孢子叶球数量的3倍，大孢子叶球转化为果实的数量不足1/10，孢子叶球数量、结实数量与样株的胸径、冠幅、树高显著相关，与其他立地因子相关不显著；孢子叶球数量在冠层间的分布呈现由上至下的递减规律，而结实数量在冠层间沿中、上、下递减，结实率沿冠层自上而下递增；孢子叶球与结实数量在树冠不同朝向上也呈现出一定的特点，但总体上差异不显著。
