Response of Nutrient Accumulation in Quinoa to Source-sink Adjustment

doi:10.7668/hbnxb.2018.05.021

Abstract

Abstract: During the quinoa cultivation,the yield and quality of quinoa are reduced due to the high rate of branch breakage and ineffective panicle.In this experiment,the randomized block design was adopted to study the effects of 6 treatments,which are cutting leaves (CLE),cutting side ears (CSE),cutting leaves and cutting side ears (CLS),topping(TOP),package the top ear (PTE) and control (CK),and to find the responses of plant nutrient accumulation to different regulation measures. The results showed that:the yield of quinoa was significantly different with the control,the unbroken spike yield of CSE treatment was highest,the yield,the stem diameter and the 1 000-grain weight of CSE were 5.2%,14.0% and 6.0% higher than that in CK,the number of branches of CSE were 10% lower than that in CK,the branches of topping was 8.0% higher than that in CK;The effect of top panicle more than that of lateral branch spike on leaf area index increasing,CSE was significantly higher than CK in photosynthetically active radiation,and there was a significant positive correlation between yield and grain weight/leaf dry weight, grain weight/leaf area and kernel per ear/leaf area. The effects of source-sink organs on the grain filling rate and dry matter accumulation was leaf > top ear > lateral ear. From the filling stage to the ripening stage of quinoa,the contribution of top and lateral branch spikes were rising trend. The contribution rate of CSE,TOP and CLE were 100.5%,87.6% and 49.0% of the control. Therefore,in the late growth period of quinoa,spike is one of the main source organs,and the top panicles have obvious advantages. It is on the basis of selection of fine varieties,appropriate management of water and fertilizer and rational close planting,and support with topping or side branches spike measures to remove the top advantage or invalid library organs,so as to achieve the purpose of regulating the flow of nutrients and improve the efficiency of nutrient accumulation,and promote the harmonious development of the source-sink,to achieve quinoa quality and yield improvement.

Key words: Source-sink, Yield, Leaf area index, Filling rate, Dry matter accumulation, Nutrient contribution rate
