摘要

摘要本研究旨在寻找一种快速、高可靠性测定土耳其赤松种子发芽能力（百分比）的方法。为此，从不同年份的不同林分和果园中采集了82批土耳其赤松种子。由于没有种子折叠，因此在第7天至第28天之间的时间段内评估发芽能力。种子分为4组（20-39.9%、40-59.9%、60-79.9%、80-100%）。发芽率指数（GPI）用相关区间的中间值表示（例如GPI_30：发芽能力在20–39.9%之间）。用11个不同的回归模型拟合了描述发芽率的4个不同发芽率区间。通过7个适应度指标确定了这些模型的最佳拟合度。结果，对于90、70、50和30的指数，当前发芽率增量分别在第13、13、14和13天达到最高值。在这项研究中，土耳其赤松种子批的发芽率可以提前7到10天预测。

A new method for early prediction of Turkish red pine (Pinus brutia Ten.) germination percentage

Abstract This study was carried out to find a method to determine the seed germination ability (percentage) in the Turkish red pine (Pinus brutia Ten.) quickly and with high reliability. For this purpose, 82 seed lots of Turkish red pine were used, collected from different seed stands and orchards in different years. Since none of the seeds were folded, the germination ability was evaluated in a period between the 7th to 28th days. The seeds were divided into 4 groups (20–39.9%, 40–59.9%, 60–79.9%, 80–100%). Germination Percentage Index (GPI) are expressed with the mid-value of the related interval (e.g. GPI_30: germination ability between 20–39.9%). Four different germination percentage intervals describing the germination percentage was fitted with 11 different regression models. The best fit of these models was determined by 7 fitness measures. As a result, the current germination percentage increment reached the highest values on the 13th, 13th, 14th, and 13th day for the indexes of 90, 70, 50, and 30, respectively. Within this study, it has been revealed that germination percentages in Turkish red pine seed lots can be predicted 7 to 10 days in advance.
