To investigate the phenotypic plasticity in response to theheterogeneous soil water supply, ramet pairs of the species were subjected to heterogeneous watersupply by which either mother ramets or daughter ramets were in high or low soil water supply, respectively,in the Maowusu (Mu Us) Sandy Land of Nei Mongol.

Structure of ramets in clonal population of Carex duriuscula on Songnen plain of China;

Age structure and growth analysis of ramets of Chamaedaphne calyculata populations in a mire of the Xiaoxing an Mountains;

Morphological response and seasonal dynamics the ramets of Calamagrostis angustifolia populations in different habitats in Sanjiang Plain

[METHOD] Cotton plants height data collected from six sites of super-high-yield trails in two years were analyzed by date-plant height method, leaf number–plant height method and leaf number-relative plant height method, respectively.

After culturing the mutant strain,main differences were concluded by colony,mycelia and cell morphology in contrast to the wild strain.

Directed towards open fund project demand of modern agricultural equipment and technology key laboratory of Jiangsu province, then based on the analysis of infrared optical properties and working principle of detecting systems, the paper designed an infrared detecting system apply to plant targeting.
