This is very interesting Mr. Pankaj Kumar Yadav

The higher incidence of rotting in large bulbs may be attributed to higher water content. Moreover, the sprouting of larger sized bulbs in storage may also be attributed to the late time of harvesting. The colour of the outer scale is correlated with the storability of the onion. The onion bulbs with high pyruvic acid content have better storage quality. The red onion varieties have higher phenolic compounds than the white varieties, which protect them against pathogenic infection, and thus have a better keeping quality. Light red-coloured onions were found to have a lower respiration rate while comparatively higher respiration rate was found in dark red and white-coloured varieties. These show that colour and bulb size likely have an influence on storability/ shelflife of onion, however, it seems also other factors associated with postharvest and storage are attributing the storability of onion bulbs.

The pest is plague while predator is any animal or other organism that hunts and kills other organisms (their prey), primarily for food.This link shows the difference between them:

Thank You very much.

KC Dahal Dear i think it doesn't matter. Any plant journal with higher impact would be better than any specific with less impact factor.

i think the decrease of some macro plant nutrition such as N,K

Hello

It is well known that many Rosaceae fruit trees mainly use sorbitol as a translocated sugar, which is synthesized in leaves by sorbitol-6-phosphate dehydrogenase.

Dear Dr Peter Roussos, the methodolgy I suggested four years ago (see above) is now bearing fruit and the first of a series of papers on ageing monumental specimens of yew will soon be forthcoming. It is with Fellows of Brunel and Harvard Forest for revision right now. There are a few surprises, and the current methodology which yields a parabolic age/girth curve based on constant annual increment derived from John White's Forestry Commission note 250 (e.g. Tabbush and White 2006) is overturned. I believe that the method may be transferrable to monumental olives. Key is measure/re-measure data in order to inform and verify theoretical work. This ageing conundrum cannot be solved using mathematics and theory only. I will alert you when publication is complete. Keep measuring and re-measuring to the highest accuracy possible.

Hello

A long term commitment is necessary to find the best selections once you've

successfully made crosses and produced seedlings. The more seedlings planted and the longer spent evaluating them, the better the chance of finding the exceedingly rare selection with potential.

Local clones, which are exclusively of seed-origin,  poor drainage and aeration, waterlogging in heavy soils are some of the reasons. Climate change effect on flowering and fruiting may be one of the reasons. Commercial date production requires artificial pollination which ensures good fertilization and overcomes disadvantages of dichogamy (different opening time for male and female spathes) and also reduces the number of male palms (with no fruit production).

Yes , you are right Daniel.o depends on the kind of isomers that are exposed to such temperature, cis or trans form , however there is usually no difference with regard to their comparative susceptibility.

I think there are some reports in the literature:

Thank you for your answers. Actually, I rescued immature embryos after 2x X4x hybridization and obtained some seedlings. Now I would like to confirm that my new hybrid offspring are polyembryony or Monoembryony. Because, I can not wait until the fruit bearing stages of new hybrids. 

Dear Dr. Nabil,

If your proposal is in relation to plant water use efficiency, we can be a potential partner (University of Gabès, Tunisia).

Thank you a lot.

Hi Mr. Yavari

I think you should study about ion nutrient uptake modeling. Generally we have tow model uptake first: series model and second: parallel model.

I can only support the answers of my predecessors that you will need to identify the causal disease first, before you can find an effective control. To my knowledge there is a very good compendium of strawberry diseases from APS press. Generally you should check your cultivation condition and propagation material, before using plant protection products, otherwise you will not achive sustainable control. After you have found the cause you should be able to find adequate advice and effective control.
