Tomatoes varieties, Applied weight, Load bearing capacity


Tomato cultivars – Roma and Ibadan local (Ibadan L)  at stage five degree of ripeness were subjected to rupture test by application of varying weights of 1 – 2.5kg to determine the time it  takes to rupture the fresh tomato samples. Roma cultivar of 23g size took 28 min and 1.2 min to rupture under 1kg and 2.5 kg weight respectively while the same variety of 76g size took 90min and 50min to rupture under 1kg and 2.5 kg weight applied respectively. For Ibadan Local (Ibadan L) of 23g size, it took 17 min and 0.67 min to rupture under 1kg and 2.5 kg weight respectively while that of 76g size took 70 min and 15 min to rupture respectively. This result showed that for any variety, the bigger the size of the fruit, the longer the time taken for the fruit to rupture under any particular load applied. The extent fresh tomatoes are able to keep and maintain freshness in their ripen state depends on their load bearing capacity.
