Abstract

Abstract:

【Objective】 With the global climate change, the effects of elevated temperature on maize production system are increasingly complex. Lodging resistance plays an important role on the completely mechanized maize production system in present and the future. Thus, the studying on the characteristics of maize stem and lodging resistance responding to gradient warming during the whole season could provide the theoretical and practical basis to the adaptive cultivation approach in response to climate change in the future. 【Method】 Zhengdan 958 (ZD958) and Xianyu 335 (XY335) were tested as materials. Three temperature gradient of CK, CK+2℃, CK+4℃ were conducted in the greenhouse to study the effects of gradient warming on stem growth and development, stem mechanics characters, lodging resistance characters and grain yield. 【Result】 The results showed that with increasing temperature, plant height, ear height, the third internode length, stem length under the ear and above the ear were significantly higher than that of CK; CK+2℃ increased on average by 10.80%, 37.29%, 16.87%, 17.11% and 17.78%, respectively, compared to CK; CK+4℃ increased on average by 20.82%, 54.17%, 37.11%, 28.48% and 35.84%, respectively, compared to CK. Temperature increment significantly increased the ear location coefficient and stem diameter coefficient. Compared with CK+2℃ and CK, the stem diameter coefficient of CK+4℃ was increased by 15.92% and 58.99% on average, respectively. Temperature increment significantly decreased the number and area of vascular bundles of stems. Compared with CK, CK+4℃ and CK+2℃ decreased the number of central vascular bundles of third internode by 43.29% and 22.59%, respectively; CK+4℃ and CK+2℃ decreased total vascular bundle area by 40.33% and 28.68%, respectively. The effect of temperature increment on the number and area of central vascular bundle was greater than that of peripheral vascular bundle. The elevated temperature decreased the area of single peripheral and central vascular bundle, but increased that of XY335. And ZD958 had greater increment of the number of vascular bundles and area of total area of peripheral vascular bundles than XY335 under elevated temperature. Temperature increment significantly decreased the thrust resistance, puncture strength and crushing strength; Compared with CK, CK+4℃ and CK+2℃ significantly increased the thrust resistance by 50.75% and 43.75%, puncture strength by 25.41% and 29.59%, crushing strength by 22.41% and 23.58%, respectively. The thrust resistance showed significantly negative relationship with plant height, ear height and the third internode length, and positive relationship with stem diameter, moment of inertia, the number and area of peripheral vascular bundle, the number and area of central vascular bundle. XY335 and ZD958 had different responses to temperature increment in the whole season. Under elevated temperature, XY335 had higher increment of plant height, ear height, the third internode length, ear position coefficient and the stem diameter coefficient than ZD958. As the temperature rose, the area of single peripheral and central vascular bundle of ZD958 decreased, while the area of vascular bundle of XY335 increased. The decrease of the number of vascular bundle and the total area of edge vascular bundle of ZD958 was less than that of XY335. As the temperature rose, stem thrust reduction of XY335 was significantly greater than that of ZD958. XY335 showed maximum values at 25 days after silking, declined later, while ZD958 showed maximum values at the mature stage. The puncture strength and crushing strength of ZD958 were significantly negatively related to plant height, ear height and the third internode length, while positively related to stem diameter. The puncture strength of XY335 was significantly negatively related to plant height, while the crushing strength showed no significant relationship with those indexes. 【Conclusion】 Elevated temperature significantly promoted the growth and development of corn, and changed microstructure of stem, decreased the stem thrust resistance and increased lodging risk. The higher the temperature was, the greater the risk of lodging. The stem growth traits and lodging ability in different cultivars had significantly different response to elevated temperature.
