Development of the green Douglas fir in the Netherlands in different places with different methods of planting was studied by enquiry, personal research and from the literature. The climate and soil types seemed suitable. Game, insects and fungi caused little damage. The stands studied all derived from seed from north-west America but the exact ori...

The growth and development of sun and shade leaves was investigated in Populus euramericana 'Robusta', growing under various light intensities and temperatures and on a substrate optimal for the roots.Strong correlations exist between the dimensions of the various plant parts. The width of an individual growing leaf is always 2 cm smaller than its ...

Oryzalin (3,5-dinitro-N4,N4-dipropyl-sulfanilamide) and BAS 083 (l,l-dimethylpiperdinium chloride) reduced root-knot infection in tomato roots when respectively applied as a soil drench at 20 ppm and 10,000 ppm. Oryzalin reduced knot counts with various intervals between treatment and inoculation. BAS 083 reduced knot counts only when applied befor...

The effects of gibberellic acid (GA) and chlorocholine chloride (CCC) was studied on Brachiaria plantaginea initial growth. An experiment was carried out on a high infestation area in field conditions. The treatments were: CCC at 1000 and 2000 ppm, GA at 50 and 100 ppm and check. At the application time, the plants had, in average, 7 leaves and 25 ...
