Abstract yamagata, m, kouchi, h and yoneyama, t 1987 partitioning and utilization of photosynthate produced at different growth stages after anthesis in soybean (glycine max l merr): analysis by long term 13c-labelling experiments —j exp bot 38: 1247–1259 soybean (glycine max l merr var. Two cultivars of yellow soybeans were used, bmx potência rr and cd 202, and two lines of black soybean, tp and iac gene expression was evaluated using qpcr in seven stages of development from seed coats for four genotypes, at 25, 30, 35, 40, 45, 50, and 55 days after anthesis the design was. Background and aims the physiological reasons for reduced pod set in soybean (glycine max) caused by drought during anthesis are not established the objective of this study was to investigate the involvement of photosynthetic rate (a ), pod endogenous abscisic acid (aba) and exogenously applied aba and. The treatments consisted of a no-rye check, plots with rye tilled into the soil or sprayed prior to planting soybeans, treatments where rye was either mowed, harvested for forage or sprayed at anthesis, and a treatment where rye was left for the duration of the soybean growing season the rye was planted on september 26,. Physiological mechanisms regulating flower abortion in soybean 545 racemes each flower on a raceme initiated a pod 4 to 7 days after anthesis during this period, a fertilized ovule develops embryo and endosperm, and cells are dividing actively (carlson & lersten, 1987) microscopic observation.

And rye often reaches anthesis after that windowanother reason for wanting to plant first and then crimp here is the info for one paper that describes this practice in a nt organic vs conventional experiment: organically managed no- tillage rye–soybean systems: agronomic, economic, and environmental assessment. Soybean (glycine max [l] merr cv wye) seeds and pod wails were determined from anthesis to maturation using high pressreliquid chro- matographic techniques developing soybean seeds contain up to 12,200 ng/g fresh weight of aba compared to 330 ng/g fresh weight for pod wails in the developing seeds aba levels. And auxin a negative effect on pod setting when respective hormones are applied to racemes after the anthesis stage key words : auxin, cytokinin, flower abortion, pod set, sink formation, soybean previous studies indicated that the grain yield of soybean is determined by the number of pods more decisively than by other.
Abstract a photoperiod sensitive (sensitive) soybean [glycine max (l) merr] line and photoperiod in sensitive (i n- sensitive) line were used to determine the critical seedling stage before possible floral induction and the length of photoinduction required for anthesis seedlings of each entry were grown in pots and. Development was studied in another experiment in the final experi- ment, the k supply was changed at anthesis to determine the relative importance of potassium supplied during either vegetative or repro- ductive growth on yield and composition of seed materials and methods experiment 1 soybean plants ( glycine max.
A research study was established in 2011 in a soybean and corn rotation with cover crops planted soon after each crop harvest in the fall a variety of complex cover crop mixtures were evaluated ranging from single specie to 7 specie mixtures cover crops were terminated in the spring soon after anthesis of the cool season. Post-anthesis glyphosate applications did not influence seed production, but reduced seed weight and viability by 50 and 96%, respectively therefore, glyphosate applied just before the woolly cupgrass inflorescence begins to emerge from the leaf sheath (as late as the r1 stage in soybeans) is an effective strategy to.
