Study on Yield Formation and Matter Production Characteristic of Super-high Yield Population of Super Rice in Chengdu Plain LAN Han-Jun-1, LI Xu-Yi-2, JIANG Xin-Lu-2, CHI Zhong-Zhi-2, ZHENG Jia-Guo-2*, LUO Le-3, QIU Chuan-Zhi-1 2014, 20(1): 41-43.  DOI: 10.3969/j.issn.1006-8082.2014.01.009 Abstract ( )   PDF (395KB) ( )    The yield formation and matter production characteristics of super-high yield population of super rice varieties Ⅱ-You 602, dexiang 4103, Q-You 8 were studied. The results showed that increasing the seed setting percentage and storage-capacity was very important for super rice from medium yield （less than or equal to 9.0 t/hm2） to high yield （from 9.0 t/hm2 to 10.5 t/hm2）  following the grain per ear improved. However, the realization of super-high yield （greater than or equal to 10.5 t/hm2） depended on the further increasement of seed setting percentage under the condition of great sink capacity in super rice. Additionally, the yield of super rice was positively correlated with the matter accumulation amount of different growth stages after the tillering stage, respectively. The key to attain the high yield of super rice was to enhance the capacity of matter production after the heading stage, and it's essential to increase the matter production in the heading period for achieving the super-high yield of super rice.

The results indicated that the growth period of two varieties were prolonged under the waterlogging stress. Compared to CK, the height of rice decreased in the early period, but the height of 2 d treatment and 4 d treatment increased in the mature period. The green leaves, green leaf area, root length, root surface area, root volume, root activity and SPAD significant reduced with the aggravate of waterlogging stress. After recovery growth, the SPAD and other characteristics of rice closed to the control, and then the gaps increased in maturity because of premature decay. The yield of two varieties decreased with the time of inundation, the yield of 6 d treatment had dropped to about 50% of the control. The reduction of yield was result from the decrease of total grains, the increase of empty grains and the decline of seed setting rate.
