Similar growth stages of each plant species are given the same BBCH code. Each code has a description and important growth stages have additional drawings included. The first digit of the scale refers to the principal growth stage. The second digit refers to the secondary growth stage which corresponds to an ordinal number or percentage value.
Saccharum spontaneum (wild sugarcane, [1] kans grass) is a grass native throughout much of tropical and subtropical Asia, northern Australia, and eastern and northern Africa. [2] It is a perennial grass, growing up to three meters in height, with spreading rhizomatous roots. [3] [4] The plant has hybridized with Saccharum officinarum, a ...
It originated in New Guinea, [1] and is now cultivated in tropical and subtropical countries worldwide for the production of sugar, ethanol and other products. S. officinarum is one of the most productive and most intensively cultivated kinds of sugarcane. It can interbreed with other sugarcane species, such as S. sinense and S. barberi.
The second domestication center of sugarcane is India, Indo China , southern China and Taiwan where S. sinense was a primary cultigen of the Austronesian peoples. Words for sugarcane exist in the Proto-Austronesian languages in Taiwan, reconstructed as *təbuS or **CebuS, which became *tebuh in Proto-Malayo-Polynesian.
It is also known as available water content (AWC), profile available water (PAW) [2] or total available water (TAW). The concept, put forward by Frank Veihmeyer and Arthur Hendrickson, [3] assumed that the water readily available to plants is the difference between the soil water content at field capacity (θ fc) and permanent wilting point (θ ...
Saccharum is a genus of tall perennial plants of the broomsedge tribe within the grass family. [5] The genus is widespread across tropical, subtropical, and warm temperate regions in Africa, Eurasia, Australia, the Americas, and assorted oceanic islands. Several species are cultivated and naturalized in areas outside their native habitats.
Water stress is the most ubiquitous stress factor, often denoted as K w. Stress coefficients tend to be functions ranging between 0 and 1. The simplest are linear, but thresholds are appropriate for some toxicity responses. Crop coefficients can exceed 1 when the crop evapotranspiration exceeds that of RET.
The most recognizable characteristic of this disease is a black or gray growth that is referred to as a "smut whip". [1] Resistance to sugarcane smut is the best course of action for management, but also the use of disease free seed is important. On smaller scale operations treatments using hot water and removing infected plants can be effective.
