3. DECAY PREDICTION. Unfortunately, decay prediction models for stone fruit have not been developed yet. A possible method of disease prediction might consist of prior to commercial harvest placing fruit of more advanced maturity into a plastic bag with wet paper to induce decay development. If decay develops rapidly, this may suggest that some lots of fruit receive additional preharvest fungic...

Urinary stone disease is global problem and is due to alteration in the normal crystallization environment of urine in the urinary tract systems. Major factors responsible for crystal formation are super-saturation of Ca salts and level of crystallization inhibitors (Citrate & Phytate). Excessive citrate intake makes the urine more alkaline (pH between 6 and 7). This can be achieved by oral adm...

Pectin rich fruit juices need enzymatic treatment for clarification. As fruits are rich in pectin, pectinolytic treatment can efficiently reduce viscosity resulting in clarified fruit juice. Enzymatic treatment of mango pulp results in 80% recovery of total juice present in the fruit. Use of pectin degrading polygalacturonases increases both fruit juice extraction and clarification. Polygalactu...

Research to date indicates that post-transcriptional gene silencing (PTGS) is an effective strategy for the development of stable high-level resistance to Plum pox virus in plum. Field tests in Poland, Romania, and Spain show that after 5–6 years of natural aphid vectored inoculation, trees of the PTGS clone C5 remain virus-free. The effectiveness of transgene-based PTGS for imparting potyvirus...

We studied the influence of sucrose and nitrogen concentration on in vitro flowering and fruit setting in elongated shoots of Withania somnifera. BA (1.5 mg/l) and IAA (0.3 mg/l) on MS medium supplemented with 4% sucrose showed 67% of in vitro flower induction frequency, 9 flowers/shoot, 4 fruits/shoot and 11 seeds/fruit in elongated-shoots. Different concentrations of nitrogen sources (L-gluta...

Shi, Biying. M.S., Purdue University, May 2015. Growth Parameters for 'Golden Delicious' Apple Trees (Malus × domestica Borkh.). Major Professor: Peter Hirst. High yield and high quality of tree fruit result from appropriate orchard design and management practices. This requires an accurate knowledge of vegetative growth, branching, and flowering processes of fruit trees. Tree development knowl...
