Abstract


Vegetative and Generative Characters of Aluminium Sensitive Rice Varieties. Aluminium (Al)
tolerant mechanism in rice has not been fully understood. The objective of this research was to
study the vegetative and generative characters of Al sensitive rice varieties. Five days old of rice
seedlings were growned on minimum culture solution containing 15 ppm of Al for 72 hours and
then transferred to non Al-treated culture solution for 48 hours. The selected seedlings was
measured based on RRG value. RRG value was determined based on after Al-stress. This research
was held at Greenhouse in Faculty of Agriculture, University of North Sumatera Utara, Medan,
from May until October 2012, using latin square Design with treatment that was rice varieties:
Inpari 3, Inpari 4, Inpari 10, Inpari 12 and Inpari 13. Data analysis showed that varieties with Altreated
were significantly different the vegetative stage, the flower initation, the time of harvesting
and the generative stage time. Varieties were not significantly different the plant height, the number
of tillers, the number of productive tiller, the panicle length, the flag leaf length, the number of
panicle branches, the number of empty grain per panicle, the grain weight per panicle and the 1000
grain weight.
