- David Pattemore talks about avocados flowers and the research being carried out by his team at Plant & Food Research to discover the effects of cooler temperatures on the flowers.
After an initial career in conservation, David headed to Princeton University on a Fulbright Award in 2005 to begin his PhD.
As a scientist with Plant & Food Research he now studies the pollination of economically important crops, bringing an ecologist’s perspective to production systems.

Wow David, a pollination expert that's so stinking cute? This is some serious science I never knew about. I'll bet your mother was surprised when you told her, "Mom, I want to become a pollination expert when I grow up," lol! No darn bees around here in Feb:( Thanks so much for sharing your knowledge. I'm on it. Subscriber from Florida.
I've been researching avocados the past few days, they're so fascinating!
This was my best year ever thanks to the bees , South Africa
Thank you you have explained what I wanted to know. I have them coming up every where in my garden where I put the scraps . So I have to dig them out all the time .
I am quite grateful for this video...even if it did not directly address a specific avocado specie. A little over 3 years ago, I bought a young grafted Bragdon purple avocado. Only about 2 feet tall, it already had young avocadoes which was exactly tantalized me to buy that small tree for a lot of money. That same year, the 4 baby avocadoes grew well for a time. Eventually, the squirrels brought down three of them of them and I was left with a single one which I picked as soon as it got completely purple (in color). Last year and this one (2021) the young tree was covered with blooms. EVERY FLOWER dropped and so were the few fruits which had already gained formation. I cried and use a profaned word! As to the cause of the droppings, I think it has to do with the quality of the soil. I am DONE with avocado cultivation!
Thank you for the video and your work. Maybe I misunderstood but 0,3% of 1 million would give 3000 fruits not 1000.
Great video.thanks for sharing
Great video
very useful I hope other videos can also provide information that is useful for fellow Aamiin and awaited always other videos ..
hi, thanks for the informative video....hmmm. unusual. my tree is flowering now, so mid Autumn. its approx 10 years old, grown from seed in a pot for first 5 years. only now have i ever seen the flowers, not masses like your trees but quite a few, it has had a huge growth period, so happy in the spot and out of the shared pot. lol.
should I remove these first flowers and hope it flowers again in summer. Hibiscus Coast location so quite tropical ish.
GREAT INFORMATION
Hi David ,, has anyone understood how the evolution to the unique pollination system came to produce the avocado fertilization?
Have to worked out why the type A and B has a different flowering mechanism and window ?
Great video, I have an Etinger Avocado in Israel, Last year I got hundreds of flowers and small Avocados, but most of them fell, and only 6 survived. They were huge and delicious. How can I get much more to hang on this year? Thanks Blessings.
Awesome thanks for sharing bro
thanks for great amount of information. do you know why Wurtz Avocado (little cado dwarf) is branded both A and B type? most other avocados are either A type or B type.
Thx so much for your video and the research that you've been working on. I realize that you're in NZ, and I'm aware of the manuka myrtle. I know that the bees absolutely love this tree. I have been studying the Chinese 5 Elements for many years now, and have observed that there are certain plants/trees that carry an elemental vibration that the bees do NOT prefer, like avocado trees (although they will visit these plants as a secondary preference). I believe (and would like to prove in some way) the truth of this. My theory is that the avocado trees would pollinate much better if they receive visitation from some other insect species, although I don't know which ones yet!! 😊 So, maybe you could do some investigations with this? I don't believe the answer lies in any insects coming from the Hymenoptera, Coleoptera or Diptera Orders. Of course, I'm aware that if you bring in non-native insects, then you might be opening the door to an imbalance in the NZ native environmental/biodiversity space (invasive species). Anyway, thx for taking time to read this, and please keep me posted if you have found out some answers!
All over avocado trees in south Florida are flowering
At the trunk. Any idea. Mutation. Chemtrails?
do the female avocado's flower will only turn into avocado fruit? how about the male avocado's flower?
Fascinating; thank you for the info
avocado is great1! i like
I have avocado tree, its been 5 yrs old now. But still no fruit to produce. It has a flower november.
Hello.. How many kg a 13 years old tree should carry ?
A large fruitset results in small poor quality fruit. There is a limited amount of nutrients to go round. I tend to thin my fruit to stop rub, nutrient allocation etc
Looks like hemp flower
What about those fruits on the ground??
How can we know male and female plants?when we planting avocado how many female plant between male plant should plant?
Avocado is a monoecious plant, meaning the flowers are hermaphroditic and have both male and female organs. The striking thing of avocados is that the flowers open first as female flowers for about a couple hours, then closes and the next day open up again but this time as male flowers.
@@GustavoRodriguezRodAG I thought it changed male to female in the same day.
@@therespectedlex9794 The tree has flowers open in male and female stages on the same day, but not the same individual flower.
What are the chances that they only have type A 🥑 varieties in that grove? I’d say close to zero.
I bought a flowering/fruiting avocado tree and since it's been planted, it has not produced a single FLOWER in two years. Any suggestions? Please help!
Add potassium fertilizer
@@leif-zu7cb I'll try, thanks!
Hi David, I have Avocado plant, tree now 5 years old but it doesn't get any flowers. What to do?
Hello,I live in central Florida and also have an avacodo tree that is about the same age and eight feet tall....but not one flower.
Is it requred more than one plant for polination
cool
Maybe a moth pollenator
Mr student biology teacher sir (only joking), I thought it was male and female in the same day?
Spray honey/water on the flowers
1:3 1honey 3 water
...daniel???
Seems like your shotting at a moving target. Temperature, wind, insect pollinators, and or avocado pollinators.
Wow, I am just trying to grow an avocado tree. After listening to the complicated pollination process I Might as well stop as I will never get fruit....
You're lucky my avocado tree haven't bear flower yet alone fruit after 2 years
2 years? No wonder. Don't expect miracles.
Most avocado trees take 10-15 years to reach maturity to flower, if it was grown from seed, and even so it can turn out to be an infertile tree which only one can it tell AFTER that 10-15 years.
As for grafted avocado trees, it will still take around 7 years (half the time) to reach maturity for it to even flower, and likewise, can turn out to be an infertile tree.
@@littlebluedolphin There is flowers but it did not turn into fruits
@@tunbadly In that case, either there's no pollinators visiting the flowers, or that the window between male and female flowers blooming never coincides or the window is too short, so there's no cross pollination occuring for the tree to bear fruits.
