| الوصف: | Changes in agronomic characters and the profile of various endogenous phytohormones during tuber development were studied in Dioscorea opposite (Chinese yam) cv. Guihuai 16. Tuber development exhibited a sigmoidal growth pattern according to the changes in tuber agronomic characters. The growth cycle of yam tuber could be divided into three stages: initiation stage, enlargement stage, and maturation stage. Moreover, the enlargement stage could be separated into three phases—slow growth phase, rapid growth phase, and late growth phase. Endogenous changes in phytohormones were associated with developmental changes in the tubers. The pulses of bioactive gibberellins (such as GA3 and GA4) were measured in tubers. The highest contents of GA3 and GA4 were reached 90 days after field planting, corresponding to the beginning of the rapid growth phase of tuber enlargement. Changes in trans-zeatin (tZ), jasmonic acid (JA), indole-3-acetic acid (IAA), and abscisic acid (ABA) levels were also observed, and seemed to be related to tuber enlargement at different phases. Continuous increases in JA and tZ contents accompanied tuber enlargement. Transient pulses of both IAA and ABA contents were also observed at the start of tuber rapid growth. Additionally, a second peak level of IAA was detected at the tuber maturation stage. These results suggest GAs play a key role at the beginning of the tuber rapid growth stage, and there is a close relationship between whole tuber enlargement and the contents of JA and tZ. Moreover, it is suggested that IAA and ABA also may be linked to the beginning of tuber rapid growth, and IAA also seems to be correlated to late tuber maturation. |
