为实现烤烟蒴果发育的实时定量监测，采用全自动颜色计测定蒴果颜色参数，采用电导率仪测定种子的活力。结果表明，授粉后10~20 d，蒴果的干鲜重持续增加，颜色参数黄度b*和色相角度h逐渐变大；授粉后20~50 d，蒴果的干鲜重持续减小，颜色参数亮度L*，黄度b*，色饱和度C，色相角度h逐渐变小；授粉后10~50 d，蒴果含水量和颜色参数L*持续性降低。相关性分析表明，蒴果鲜重和颜色参数L*，b*，C，h呈极显著正相关，与红度a*呈极显著负相关（P＜0.01）；蒴果含水量与颜色参数L*和h呈极显著正相关，与a*呈极显著负相关（P＜0.01）；种子发芽率和出苗率与L*呈显著负相关（P＜0.05）。其拟合方程分别为Y 鲜重=0.579 L*-1.703 a*-0.316 b*+0.499 C-0.847h+45.294（R2=0.910，P<0.05）。Y 含水量=0.907 L*-0.014 a*+0.009h+17.391（R2=0.892，P<0.05）。Y发芽率=-0.068(L*)2+4.451L*+24.212（R2=0.907，P<0.05）和Y出苗率=-0.064（L*）2+4.228L*+23.002（R2=0.905，P<0.05）。CIELAB颜色空间是一种定量化的颜色识别系统，可以较好的模拟烤烟蒴果的发育过程，辅助预测种子活力变化。

To develop a real-time quantitative method of monitoring capsule development, automatic color space and conductivity meter were used to measure the capsules color parameters and seed vigor, respectively. The results showed that fresh and dry weights of capsules showed an ascending tendency 10 to 20 days after pollination, the color parametersb* andC showed the same tendency during that time. Capsule weight started declining 20 days after pollination, with parametersL*,b*,C, h also declining. Water content and color parametersL*of capsules showed a consistently ascending tendency during the whole development stage from 10 to 50 days after pollination. Correlation analysis showed that there was a significant correlation between capsule fresh weight and all five color parameters (P<0.01). Capsule water content showed a significant negative correlation with color parametera*value and positive correlation withL* and h (P<0.01). Seed germination rate and emergence rate showed significantly negative correlations with L*(P<0.05). Regression equations were established respectively as follows:Yfresh weight=0.579L*-1.703a*-0.316b*+0.499C-0.847h+45.294 (R2=0.910,P<0.05);Ywater content =0.907L*-0.014a*+0.009h+17.391 (R2=0.892,P<0.05);Ygermination rate=0.068 (L*)2 +4.451L* +24.212 (R2=0.907,P<0.05);Ygermination rate=0.064(L*)2+4.228L*+23.002 (R2=0.905,P<0.05). CIELAB color space is a quantitative method for color measurement, which could be used to imitate the development of tobacco capsules and predict the change of seed vigor.
