Leaf-level morphological and physiological responses of mature, winter-deciduous, shade-tolerant Acer saccharum Marsh. trees to gap formation caused by selection harvest were studied experimentally over a 2-year period. We found no evidence for either physiological stress or positive acclimation following gap creation during the 1-2-week post-harvest period. Rather, lower-canopy leaves showed g...

In 1987, J. Daniels and B. T. Roach published an exhaustive multidisciplinary review of evidence permitting the domestication and the early evolution of sugarcane to be traced. We try here to synthesize the new data that have been produced since, and their contribution to the understanding of the global picture. It is now highly probable that sugarcane evolved from a specific lineage restricted...

The present investigation highlights the free radical scavenging activity of Melochia corchorifolia, Sida acuta and Saccharum officinarum leaf extracts and their Phenolic contents by determining DPPH, Nitric oxide, Hydroxyl and Hydrogen peroxide scavenging activity. The shade dried leaves were coarsely powdered and subjected to fractional extraction by using chloroform and ethanol. The extracts...

Saccharum spontaneum L. known as Kasa (Family: Poaceae) is a traditional herb, it have excellence medicinal value; have been advocated in the treatment gynaecological troubles, respiratory disease. Roots are used as galactagogue and diuretic and in ayurveda system roots are also used as astringent, emollient, refrigerant, diuretic, purgative, tonic, aphrodisiac and useful in treatment of dyspep...

The genus “Saccharum” includes about 150 species under the family “Poaceae”. This occurs throughout India along the sides of the river and tropics of old world, it is widely distributed in Andhra Pradesh, Vellore district in Tamilnadu. Scientific information on their pharmacognosy, Phytochemistry and pharmacology are very scant. Hence the current study describes some pharmacognostical and preli...

This article assesses sugarcane yield gaps (YG) in Brazil to determine the degree to which production can be increased without land expansion. In our scenario assessments, we evaluated how much of the projected sugarcane demand to 2024 (for both sugar and bioethanol) can be satisfied through YG closure. The current national average yield is 62% of yield potential estimated for rainfed condition...

Introduction The nature of the processes reported here should not be regarded as occurring independently of other' reactions for the soil has a universe of its own in which a great number of different reactions are occurring simultaneously with one another. The type of investigations conducted below are thus only a part of a great number which can and do occur, and have 'been investigated in th...

The events in Natal of 100 years ago are of particular interest at the moment, as in those days the foundation was being laid of an agricultural industry which was destined to become one of the largest in South Africa. It is also of importance to realise that the cultivation of sugarcane was the early outcome of the trial of many crops, all of which eventually disappeared or only played a small...
