Other claims from this paper (16)

Observation Frost killed young ears in low winter type wheat and induced late tiller ears and delayed heading.
Observation Frost caused 68.3% dead stems in the severely damaged field.
Observation Frost caused 48.1% dead stems in the intermediately damaged field.
Observation Frost caused 23.3% dead stems in the lightly damaged field.
Association Damage differences were likely related to growth and developmental stage.
Observation Damage changed late stem number, stem length and stem diameter.
Observation Damage delayed wheat heading.
Association Frost damage degree correlated strongly with changed morphological characters and those characters correlated with each other.
Observation Frost decreased complete grains and their proportion.
Observation Frost increased incomplete grain quantity.
Observation Frost decreased thousand grain weight.
Observation Slightly damaged wheat fields had no actual yield decrease.
Observation Intermediate damage reduced wheat yield by about 30%.
Observation Severe damage reduced wheat yield by about 70%.
Method / resource Late stem productivity may estimate frost related wheat yield loss.
Association Late stem productivity correlated significantly with delayed heading days, stem length and stem diameter.

Other claims from this paper (9)

Association Plant and unit tiller weight increased throughout the season in the herbage removed at each cut.
Association The number of tillers declined, especially before shooting began.
Intervention effect Cutting up to 5 May did not affect the date of ear emergence.
Intervention effect Plants cut on 19 May had a slightly delayed date of ear emergence.
Intervention effect Plants treated subsequently flowered much later.
Observation The interval following defoliation before flowering was fairly constant.
Intervention effect Cutting on and after 7 April depressed fertile tiller formation with increasing severity.
Observation Only vegetative tillers appeared in the recovery growth after treatment at the beginning of August.
Association Seed yield per plant declined with the decrease in fertile tiller numbers.

Other claims from this paper (13)

Intervention effect Deficient soil moisture increased total sugar content in the leaves and stems of soybean
Intervention effect Excessive soil moisture increased starch content of soybean plants
Intervention effect Deficient or excessive soil moisture decreased nitrogen content in each organ of soybean plants
Intervention effect Deficient and excessive soil moisture inhibited nitrogen absorption by soybean plants
Intervention effect Inhibition of nitrogen absorption by soil moisture stress was greater when applied during the flowering period than during earlier periods
Intervention effect Deficient soil moisture reduced accumulation of carbohydrates in soybean plants
Intervention effect Excessive soil moisture gave a higher amount of accumulated carbohydrates in soybean plants
Intervention effect Vegetative growth of soybean was retarded when soil moisture was deficient or excessive during the earlier periods
Intervention effect Flower and pod shedding percentages of soybean were little different from control when soil moisture was stressed during the earlier periods
Intervention effect Number of flowers produced by soybean was almost the same as control when soil moisture was stressed during the flowering period
Intervention effect Shedding percentage of soybean was much higher when soil moisture was stressed during the flowering period
Intervention effect Amounts of carbohydrates translocated from leaves and stems to pods of soybean were reduced under soil moisture stress
Intervention effect Amount of nitrogen translocated to sexual organs of soybean was reduced under soil moisture stress
