introduction sugarcane, a plant which sugar is extracted from, is planted in vast areas with hot and humid climate. brazil is the largest producer of sugarcane in the world. the next five major producers, in decreasing order, are india, china, thailand, pakistan and mexico. sugarcane is a tropical, perennial grass that forms lateral shoots at the base to produce multiple stems, typically three ...

Several etiological and epidemiological studies have been undertaken to determine the disease causal agent and the mechanism of spread of Cassava brown streak disease (CBSD). Until recently, two distinct potyviruses have been reported to cause the disease. These are Cassava brown streak virus (originated in Tanzania but most widely spread) and Ugandan Cassava brown streak virus (reported in Uga...

The standard two-step methods for grafting horticultural crops involve cultivating the rootstock a period of time and then connecting scion. Medicinal Cannabis differs from most annual because it is usually clonally propagated cuttings. We developed methodology specifically medicinal Cannabis, involving single step, in which freshly cut scion grafted to donor stem that will become rootstock. Th...

The thermal stress caused by high temperatures on cut rose flowers grown in greenhouses is a major environmental impact that reduces the yield of growing during summer. To confirm resistance grafted to high-temperature stress, roses were greenhouse summer season and analyzed for yield, quality, root activity, photo-physiological characteristics. A morphological change was observed stomata flowe...

Grafting has been increasingly used to overcome soilborne pathogens. The commercial rootstock hybrids AF-8253 (Sakata) and Fortaleza (Takii), as well Embrapa’s new hybrid, BRS Acará, were evaluated rootstocks for the bell pepper Margarita (Syngenta) Pampa (Clause) scions, under natural infestation of Ralstonia pseudosolanacearum, upon artificial inoculation with a) ten isolates, b) one Phytopht...

We find a parametrically light dilaton in special confining theories three dimensions. Their duals form what we call scion of solutions to the supergravity associated with large-N limit Coulomb branch N=4 Super-Yang-Mills (SYM) theory. The description contains one scalar bulk mass that saturates Breitenlohner-Freedman unitarity bound. new are defined within supergravity, they break supersymmetr...

Experience with tip grafting avocados has shown that there are distinct seasonal differences in success. Grafts made during the winter and early spring months, especially in January, February, and early March, are nearly 100 per cent successful, while in late spring, summer, and early fall the percentages are often much lower. This is especially true with certain varieties. For example, results...

In California, first-generation table grape vineyards were planted on their own roots. But in recent years growers have been replanting onto acreage previously in grapes more often. Grafted plants are being sought to overcome nematodes and other site-related problems. We investigated the etiology of the decline and death of ‘Redglobe’ table grape scions propagated on different rootstocks, using...
