01 Feb 2018TL;DR: The results of morphological observations showed different types of plant growth, which in the lowlands and medium plant growth types spread, twisted, more branches, wider leaf area, however, the plateau of plant Growth was relatively dwarf, erect, no twist, huddled and short rods and small leaf area.
Abstract: This research was conducted at three locations in low, medium and high plains. This study was aimed to determine the morphological changes and sugar content of sweet potato caused by potassium dose treatment and climate change. Data was analyzed by factorial randomized block design in time series with two factors. The first factor was Altitude: A1 (50 meter above sea level (MASL)), A2 (750 MASL) and A3 (1450 MASL). The second factor was Potassium: K0 (0 kg/ha), K1 (50 kg/ha), K2 (100 kg/ha) and K3 (150 kg/ha). The data of plant morphology change and sugar content was descriptively analized, while agronomic and harvest component data analysis by F test and continued with Duncan Multiple Range Test. The results of morphological observations showed different types of plant growth, which in the lowlands and medium plant growth types spread, twisted, more branches, wider leaf area. However, the plateau of plant growth was relatively dwarf, erect, no twist, huddled and short rods and small leaf area. The tuber weight per plant, number of tuber yield and tuber weight per plot in high altitude were significantly higher than lowland and medium. Similarly, increased altitude will be increased the sugar content significantly.

TL;DR: The results showed that colchicine concentrations at 5,000–6,000 ppm affected the size of vegetative and reproductive parts such as the leaves, infl orescence and staminate fl owers compared with normal plants.
Abstract: A study on the effect of colchicine on the physic nut (Jatropha curcas Linn.) was carried out at a research site in Pathum Thani province. Colchicine was used to treat plants of physic nuts of clones FF25B-14 and FF20SBr-3 at 500–8,000 ppm for 10 d. The results showed that colchicine concentrations at 5,000–6,000 ppm affected the size of vegetative and reproductive parts such as the leaves, infl orescence and staminate fl owers compared with normal plants. The treated plants showed larger stomatal size than nontreated plants. Study of the chromosome number revealed that the treated plants had doubled chromosomes (44) compared to the normal plants. These plants were assumed to be 4n or tetraploids while the normal plants were 2n or diploids (2n = 22). Both the vegetative growth and yield of the tetraploid plants were lower than in normal plants.
