EFFECT OF TEMPERATURE DURING GRAIN FILLING ON WHOLE PLANT AND GRAIN YIELD IN MAIZE (Zea mays L.)

B. BADU-APRAKU; R. B. HUNTER; M. TOLLENAAR Canadian Journal of Plant Science 1983. doi:10.4141/cjps83-040

Other claims from this paper (9)

Intervention effect Higher temperatures reduced whole-plant dry matter accumulation during grain filling.
Intervention effect Higher temperatures shortened the period from 18 days after silking to complete leaf senescence.
Intervention effect Higher temperatures lowered the rate of whole-plant dry matter production to a limited extent.
Intervention effect Grain yield per plant was lower under higher temperatures.
Intervention effect Temperature had no observed effect on kernel growth rates.
Intervention effect Temperature had no observed effect on kernel number per ear.
Mechanism Kernel dry-matter gain during rapid grain filling drew on stored assimilates and current photosynthesis.
Intervention effect At the highest temperature, remobilized assimilates accounted for a greater share of kernel weight gain.
Intervention effect Higher night temperatures may increase the share of kernel gain supplied by remobilized stored dry matter.

Other claims from this paper (16)

Intervention effect BHC adversely affected chilli germination and survival.
Intervention effect Nuvacron adversely affected chilli germination and survival.
Intervention effect Nuvacron injured chilli germination and survival more than BHC.
Intervention effect BHC produced abnormalities in dividing chilli PMCs.
Intervention effect Nuvacron produced abnormalities in dividing chilli PMCs.
Intervention effect Nuvacron caused a higher frequency of chilli PMC abnormalities than BHC.
Observation Chilli pollen sterility nine days after BHC spray was low.
Observation Chilli pollen sterility nine days after Nuvacron spray was high.
Association With increasing insecticide dose, chilli percent of anbormal meiotic cells showed increase.
Association With increasing insecticide dose, chilli percent of pollen sterility showed increase.
Intervention effect Chilli yield under BHC treatments was uneffected.
Intervention effect Chilli yield under normal concentration (0.04%) of Nuvacron was increased.
Intervention effect Chilli yield under highest concentration (0.12%) was decreased.
Intervention effect Chilli yield under Nuvacron 0.08 percent was on par.
Recommendation The authors recommended 0.04 percent Nuvacron for pest control and increased chilli yield.
Recommendation The authors advised against doses above the recommendation because of chromosomal abnormalities and yield reduction.

Other claims from this paper (4)

Intervention effect Acid rain at pH 3.6 significantly reduced corn seed yield relative to pH 5.6 rain.
Intervention effect Acidic agar medium inhibited corn pollen germination and tube elongation.
Intervention effect Pollen germination on silks exposed to pH 3.6 rain fell by up to 75% relative to pH 5.6.
Mechanism The authors suggest acid rain could reduce corn yield under limited-pollen conditions by inhibiting reproduction.
