Regulated ripening of Coffea arabica L. in Kenya: studies on the use of 2-chloroethyl phosphonic acid

, : Regulated ripening of Coffea arabica L. in Kenya: studies on the use of 2-chloroethyl phosphonic acid. Acta Horticulturae (49): 125-135

Sprayed once at 1400 p.p.m. ethephon failed to concentrate the harvesting of trees bearing crop from multiple flowerings, although ripening was still brought forward. At a low altitude site (1522 m) where fruits develop quickly, ethephon at 1400 p.p.m., applied to 28-week-old fruits from a single large flowering, spread the harvesting period over 8 compared to 5 weeks required to harvest the unsprayed trees.

Lawrence, 2013: A petrographic and geochemical record of climate change over the last 4600 years from a northern Namibia stalagmite, with evidence of abruptly wetter climate at the beginning of southern Africa’s Iron Age. Stalagmite DP1, a speleothem 1.6 m in length from Dante Cave in northeastern Namibia, provides a paleoclimate record of a gradual transition from wetter to drier conditions from 4.6 to 3.3 ka BP, a variable but pronounced dry period from 3.3 to 1....

Ovarian weight and related indices such as gonadosomatic index were used to index fecundity, egg maturity, and spawning season in gizzard shad Dorosoma cepedianum. Individually, in simple regression, fecundity and mean egg volume each accounted fo...

The diphenylamine reaction used for the measurement of DNA was found sensitive to light activation but only when acetaldehyde was omitted from the reagent. The increase in sensitivity of the overall reaction was dependent on several factors, namel...

We report the case of a 27-year-old female who had an allergic contact dermatitis to topical corticosteroids belonging to the corticosteroid groups A and D. Upon oral treatment with prednisolone a disseminated exanthema began within 24 h. Patch te...

Our earlier method to detect and quantitate sulfamethazine (SMZ) in milk at the 10 ppb level was modified to quantitate SMZ in pork tissue. Sulfabromomethazine (SBZ) is added to the tissue as an internal standard. SMZ and SBZ are extracted from th...

In addition, an increased frequency of females with constant di...
