Here a 10-year census of aphids on winter wheat tillers and a 6-year census of aphids on wheat ears are analysed.
The tillers used for aphid counts (see above) were cut from a randomly selected section of the row.
In this experiment too, the age of the seedlings appeared to be the most important factor affecting rice growth and tiller production.
A soil insecticide was applied to plots at different times during the tillering phase of rice in order to manipulate the timing of weevil infestation.
The second application of carbofuran was made to appropriate plots during the period of rice growth when rice was actively tillering.
The control of tillering in the barley plant.
The leaf nitrogen content was higher and leaf mass lower (because of incomplete leaf expansion and smaller tiller size) for late than for early-sown plants.
Responses of leaf and tiller emergence and primordium initiation in wheat and barley to interchanged photoperiod.
