Influence of soil moisture levels and packaging on postharvest qualities of tomato

Abstract: 
Plants respond to reduced soil water availability without experiencing any detectable change in shoot-water relations. The tomato seedlings (cv. ‘Moneymaker’) were planted in plastic pots under greenhouse conditions under five different soil moisture levels (20%, 40%, 60%, 80% and 100% of the pot capacity). They were then assessed for postharvest qualities including use of different types of packaging [non-packaged (control), perforated and non-perforated high density polythene bag (HDPE)]. Plant growth and yield were reduced due to moisture stress but postharvest qualities were enhanced. Packaging positively influenced tomato fruit quality and extended tomato shelf life.
Les plantes réagissent à la réduction des quantités d’eau disponible dans le sol sans manifester de changement visible dans les relations eau-racines. L’influence du stress hydrique et de l’emballage sur les qualités post-récoltes a été étudiée sur la tomate cultivée (cultivar ‘Moneymaker’) dans des pots en polyéthylène sous 5 niveaux de déficit en eau disponible (20%, 40%, 60%, 80% et 100%) en conditions de serre afin d’identifier les effets d’une irrigation déficitaire sur la croissance et le rendement de la tomate, ensuite et d’évaluer les qualités post-récoltes sous emballages (perforés, non-perforés et nonemballés). La croissance et le rendement avaient été réduits sensiblement sous l’influence de l’eau déficitaire mais les qualités post-récoltes avaient été améliorées. L’emballage a aussi eu d’influences positives sur les qualités de fruits et ainsi prolongé la durée de conservation avant la vente des produits.

The 2012 RUFORUM Biennial Conference is the third in the series. The main objective of the Biennial conferences is to provide a platform for agricultural research for development stakeholders in Africa and beyond to actively exchange findings and experiences, while at the same time learning lessons towards improving performance of the agricultural sector and ultimately people’s livelihoods. The biennial conference is RUFORUM’s most comprehensive meeting for the diversity of stakeholers in agriculture. It is especially dedicated to graduate students and their supervisors, grantees in RUFORUM member universities and alumni. It is a platform for peer review, quality control, mentorship, networking and shared learning. The third Biennial Conference was attended by 657 participants.This record contains an extended abstract accepted under the theme of Food Science and Value Addition.
