Variation in seed yield and quality in relation to fruit position were determined in hot pepper cultivar during 2004 and 2005. Fruits were harvested from different layers (first, second and third) of the plant. In each layer, fruits were harvested 65 days after anthesis to obtain similar seed maturation stage. Fruit weight, seed yield, seed moisture content, germination at 15 and 25 degrees C, germination after controlled deterioration and mean germination time were determined. Fruit weight and seed yield gradually decreased throughout fructification, from the first to the third layer. Seed moisture content did not change between layers. Moisture remained at values of about 48-50%. The seeds extracted from fruits of the first layer had higher germination and vigour, lower mean germination time than those from the other layers. Seeds from the third layer caused decline in seed quality especially vigour with 69.3%.
2004年和2005年期间,对辣椒品种中与果实位置相关的种子产量和质量变化进行了测定。从植株的不同层(第一层、第二层和第三层)收获果实。在每层中,花后65天收获果实以获得相似的种子成熟阶段。测定了果实重量、种子产量、种子含水量、15℃和25℃下的发芽率、老化处理后的发芽率以及平均发芽时间。在整个结果期,果实重量和种子产量从第一层到第三层逐渐下降。各层之间种子含水量没有变化。含水量保持在约48 - 50%。从第一层果实中提取的种子比其他层的种子具有更高的发芽率和活力,平均发芽时间更短。第三层的种子导致种子质量下降,尤其是活力下降了69.3%。
