Relations between the elongation of wheat plant and the air temperature before winter.
[摘要] It is observed that the wheat plants sown on 15, 22 and 29 in September stopped their elongation at mean temperature of 8.2, 8.9 and 9.6 °C respectively. in field, but the plants sown on 6 and 13 in October, being perhaps due to the growth by endosperm, could elongate at such lower temperature as 6.5 and 5.5 °C, respectively.
