Title

The relation between kernel development and time of harvesting of peanuts at Katherine, N.T

HD Barrs Australian Journal of Experimental Agriculture and Animal Husbandry 1962. doi:10.1071/ea9620106

Other claims from this paper (8)

Observation Kernel yield per acre accumulated rapidly to completion without gradual slowing.
Observation Final mean individual kernel weight was almost identical across the two plantings, at 0.35 grams.
Association Differences in kernel number accounted for nearly all differences in peanut yield.
Observation The coefficient of variation for MIKW was about one-tenth of that for TKW.
Recommendation The authors suggest MIKW as a satisfactory estimate of peanut maturity.
Observation Natal Common appears mature when MIKW reaches 0.35 grams.
Method / resource Five typical plants provide a satisfactory MIKW estimate after kernel oven drying.
Observation The authors suggest mature MIKW may differ among peanut varieties.

Title

Grain yield of wheat (Triticum aestivum L.) under long‐term heat stress is sink‐limited with stronger inhibition of kernel setting than grain filling

Birgit W. Hütsch; Dana Jahn; Sven Schubert Journal of Agronomy and Crop Science 2018. doi:10.1111/jac.12298

Other claims from this paper (15)

Intervention effect Heat stress shortened the development phases of wheat.
Intervention effect Heat stress decreased total above-ground biomass of wheat by 19% to 41%.
Intervention effect At grain filling, heat stress depressed wheat grain yield by 77%.
Intervention effect At maturity, heat stress depressed wheat grain yield by 58%.
Intervention effect Heat-stressed wheat had a significantly higher ear number per plant than the control.
Observation At maturity, the ear number per plant of heat-stressed wheat more than doubled.
Observation Heat stress strongly decreased kernel number per ear by 83% during grain filling.
Observation Heat stress strongly decreased kernel number per ear by 75% at maturity.
Intervention effect Heat-stressed wheat had a 36% lower harvest index than the control.
Observation Under heat stress, wheat water use efficiency for grain decreased by 62%.
Intervention effect Heat stress did not significantly change sucrose, glucose and fructose concentrations in ears and grains.
Intervention effect Heat stress reduced sink capacity in wheat, with smaller and fewer kernels than the control.
Mechanism The sink-limiting step during kernel set is probably active transport of hexoses into the developing kernels.
Observation The supply of assimilates to wheat kernels under heat stress was not restricted.
Mechanism Heat-stressed wheat presumably transpired more without higher total water consumption.
