Water content and ion concentration gradients were measured in soil near a plane of onion seedling roots. Using the water content-matric potential rel...

In general, bees collecting nectar only, as well as bees collecting nectar and pollen, preferred male-fertile to male-sterile cultivars of onion plant...

An autoradiographic method for measuring root length in the soil using ³²P injected into onion leaves is described. The soil containing the roots was ...

Blocks of onion plants were either caged with honeybee colonies or left uncaged. Although the uncaged plants produced fewer umbels, the weight of seed...

Seeds of calabrese, carrot, onion and sugar beet were sown in the field on successive occasions. Soil integral impedance (work done in penetrating the...

In two series of experiments, the relative leaf growth rates (RA) and relative growth rates (RW) of seedlings of 8 onion cvs of diverse geographic ori...

Concentration gradients of phosphate, K, Ca and Mg were measured near a plane of onion seedling roots at a range of soil water contents, in a special ...

At higher soil water contents, chloride uptake by onion roots was greater, and the zones of depletion extended further. Models of ion transport were d...

The 'Quantimet' Image Analysing Computer was used to measure the length of roots washed out from soil, and a new autoradiographic (32P) method for mea...

The long-range, host-finding behaviour of Delia antiqua was investigated in 16 mark-release-recapture experiments in Canada using onion-reared flies f...
