Abstract:
Taking ornamental tomato ‘red pearls’ as materials that were cultivated with plastic pots of 5 different volumes，in order to explore effects of root volume on the growth and development of ornamental tomato.The results showed that with the different root volume，the growth index and the photosynthetic characteristics were significant difference，all its plant height，stem diameter，dry and fresh weight and root activity were increased and then decreased with smaller flowerpots volume.From the fruit setting stage to fruit mature period，the increase scope of T3 plant height (29.6%) was the biggest，and the increase scope of T2 stem diameter (41.48%) was the biggest；the root activity of fruit mature period was obviously lower than fruit setting stage，and the fruit setting stage of T4 was the strongest，reached 57.17 μg?g-1?h-1；with smaller flowerpots volume，the Tn of ornamental tomato increased，the WUE reduced gradually，the Gs，the Ci，and the Pn all increased and then decreased，each the Gs and the Ci of T4 were the highest，and T1 were the lowest；the Pn of T2 was the strongest.With smaller flowerpots volume，the per plant yield was increased and then decreased，the T3 was the highest with 181.24 g，and the T5 was the lowest with 124.6 g；the titratable acid，soluble sugar and vitamin C all increased gradually.On the basis of the above analysis，the flowerpots volume of T2 and T3 were suitable for the growth of ornamental tomato.
