The development and evaluation of an air pressurised fluid drill

, : The development and evaluation of an air pressurised fluid drill. Acta Horticulturae (72): 109-120

The design and operation of a pneumatically-operated pressurised fluid drill is described, together with experiments which show that very little damage was sustained by the seeds during drilling even when seeds with radicles longer than 10 mm were used. Experiments also showed that the spacing distribution of several crops obtained with this drill is comparable with conventional thin line seeding drills.

If the cells of the blue-green alga A. nidulans are put under unfavorable conditions, the pairs of photosynthetic membranes separate, vacuoles are formed within thylakoids, and degradation of the photosynthetic apparatus occurs the earlier the soo...

Interspecific hybrids between common buckwheat (Fagopyrum esculentum) and a wild relative (F. homotropicum) were produced by cross pollination and embryo rescue. Ovules were excised at 3, 5, 7 or 11 days after pollination of both pin (long-styled)...

The "catalytic triad" of serine proteases and lipases and the "catalytic diad" of phospholipase A-2 (PLA2) are the key catalytic machineries of these enzymes. We present evidence that the catalytic diad of PLA2 also plays an im...
