Canopy biomass production and stem and seed TNC were used to assess photosynthate accumulation, whereas partitioning of photosynthates were assessed using pod harvest, pod partitioning, stem biomass reduction, and harvest indices.
Physiological traits related with photosynthate accumulation and partitioning included canopy biomass dry weight at mid-pod filling, pod partitioning index, pod harvest index, stem biomass reduction, and harvest index, were measured only in Awassa and Palmira.
In this regard, QTL for traits related with photosynthate accumulation and partitioning were distributed on linkage group b03, b05, b06, and b09 with genetic pleiotropy on b03 for pod partitioning and pod harvest indices.
Parameters of the model for phenological development, leaf area expansion, radiation interception, biomass accumulation and partitioning, crop water use, root growth and water extraction, and nitrogen accumulation are derived from published studies.
Because of the use of the entire plant as a source for fermentable sugars, carbohydrate accumulation and partitioning has been extensively studied in sugarcane, probably more than in any other species [30].
In order to study the effect of N application on accumulation and partitioning of biomass and N in young trees, an experiment was conducted in 'Bing' sweet cherry trees on Gisela®6 rootstock during the first three years after planting.
Research was conducted to compare: (i) the relative efficiencies of rice and weedy rice in recovering fertilizer N under a competitive condition, (ii) the accumulation and partitioning of N by rice and weedy rice, and (iii) the N use efficiency of rice and weedy rice.
Data collected included soil water content (SWC), plant height (PH /vine length, leaf number (LN), tillering (T /branching, leaf area index (LAI), relative leaf water content (RWC), stomatal conductance (gs) and chlorophyll content index (CCI) as well as biomass accumulation and partitioning.
These were associated with yield, canopy biomass, and photosynthate accumulation and partitioning related traits (Table 5).
Drought and water deficit can decrease photosynthetic capacity, result in oxidative damage to chloroplasts, limit metabolic reactions, and reduce dry matter accumulation and partitioning [ 3].
