Other claims from this paper (12)

Observation B. juncea and B. rapa had higher optimum temperatures than B. napus.
Intervention effect Moderate temperature stress left dry matter unaffected.
Intervention effect High temperature stress reduced dry matter.
Intervention effect The 35/15 °C treatment injured reproductive organs in all three species.
Intervention effect Heat at flowering affected yield more than heat at pod development.
Intervention effect Heat stress reduced main stem seed yield by a mean 89%.
Intervention effect Heat stress reduced fertile pods, thousand seed weight and seeds per pod.
Observation B. rapa was more heat sensitive than B. napus and B. juncea.
Observation Pods beyond a critical developmental threshold tolerated heat stress.
Observation Genotypes resumed flowering after recovery at 20/15 °C.
Observation B. napus showed the weakest recovery from severe flowering stress and formed abnormal pods.
Observation J90-4316 and Cutlass showed similar per plant yield responses.
