Though soursop timber are comparatively straightforward to maintain and normally do not require a whole lot of upkeep, they’re fairly tough to get pollinated if left completed naturally. Because of this many growers hand pollinate the flowers. This isn’t solely to extend the fruit set price but additionally to enhance the form of the fruits and their high quality.
However as somewhat aspect be aware, so I heard that bees do not appear to love to pollinate the guayabana (soursop) flowers. It is the beetle or one thing once they get pollen sticking round their physique in a single flower and go pollinate different soursop flowers.
Anyway, allow us to try the way to pollinate the soursop timber now.
Selecting A Soursop Flower for Pollen
To pick out a flower for pollen, you must search for these which might be close to the highest of a smaller department or the flower itself is of a small dimension. It’s because these flowers are comparatively tougher to get fertilized or even when so the fruit dropping price is excessive or at instances fruits do not get developed in any respect.
Take a look at these flowers which have their three petals barely open outwards. Gently raise open one petal to have a look inside. For those who see that the anthers are calmly darker and they’re starting separate, we are able to reduce the flowers to gather the pollen.
The most effective time to choose the flowers is within the cool afternoon. After choosing the entire flowers, we are able to lay them on a bit of paper in an hermetic field or just a paper bag to guard them from moisture loss or the wind blowing the pollen away. We are able to do the pollination tomorrow morning.
The following morning, you’ll be able to break off the flower petals of the collected flowers. Shake the flowers somewhat bit so the darkish grey anthers fall onto the piece of paper.
You may then use a dry cotton swab or Q-tip to softly rub the pollen out of the pollen sac (anthers). Normally, the pollen from one flower will likely be sufficient to pollinate 6-8 different flowers.
Now we are able to get on to:
Selecting A Flower to Pollinate
To decide on a flower for pollination, you’ll search for these on the principle soursop trunk. As somewhat enjoyable reality, these fruits that develop instantly on the soursop trunk are sometimes the easiest and sweetest.
We are able to additionally search for flowers on large branches, with large flower stems or with no pests or illnesses for a superb pollination.
Some growers select flowers close to the bottom of a department or close to the bottom of a fork (like close to the assembly level on the letter Y) and never too far out. As a result of a soursop can weigh as much as 4-7 lbs (1-3 kg) per fruit, that is so the department would not must droop or bend down manner an excessive amount of when bearing the fruits.
Once you see that the three flower petals are barely open, the stigma could also be of age and mature. Gently open the petals to see the stigma inside. If it appears moist and slimy, we are able to start the pollination.
Let’s Get to Pollinating
The most effective time to pollinate is round 8-9 AM within the morning. Simply as properly, the stigma of the female-stage flower is most receptive from 8-10 AM. In full bloom time, we are able to hand pollinate the flowers each 3-4 days.
Once you do the pollination, you should utilize the index and center finger to type of safe the flower stem in place. Then, use your thumb to barely open one flower petal.
Alternatively, with a cotton swab in hand, dab somewhat pollen on. It’s okay to dip the cotton swab head a bit in water. This will enhance the pollen sticking price.
Then, gently unfold or rub the pollen onto the stigma. It might be higher if the pollen is unfold evenly throughout. Repeat this 3 times. The fruit will develop even and never too deformed or bizarre wanting.
If there’s a flower rising between two little fruits which have set on the department and also you wish to pollinate it, simply be somewhat additional cautious although. With a skillful pair of palms, it is okay. Nonetheless, if it is certainly one of your first few instances doing the job of a bee, then chances are you’ll wish to go away that sandwiched in-between flower alone.
Some poking and drilling right here and there may disturb the neighboring new fruits, inflicting them to drop. It might be an actual waste.
After Pollination
After pollination, simply go away the flowers as-is and do not contact them. About 4-7 days after hand pollinating the flowers, you’ll be able to have a test on the flower stem (or pistil).
If it appears nonetheless inexperienced and appears to have grown somewhat larger, then congratulations this implies the pollen takes and our pollination course of is full. We are able to then look ahead to the soursop fruit to type.
In one other case, if the pollination is not profitable, the flower stem will flip extra darkish, dry up and finally fall off. Higher luck subsequent time. We cannot have any soursop to get pleasure from this time.
Additionally, if a female-stage flower has been pollinated, it should nonetheless develop and turn out to be a male-stage flower and develop anthers (with pollen). Some growers, somewhat bit greedily talking, nonetheless exit and acquire the pollen on these flowers. It sadly causes the flowers to drop.
So when you have got pollinated a flower simply go away it as-is and do not go for extra pollen. You may tie some form of string or break off a small piece of the flower petal for marking which flower has receieved pollen. It might be a safer guess.
After the male stage, some pollinated Annona flower petals will dry up and switch extra darkish. Some growers thought that these darkened flowers had been lifeless and thus plucked them off.
However earlier than you accomplish that, have somewhat sneak peak inside. If there appears to be somewhat fruit rising inside, then the pollination takes. The flower petals turning darkish and dry after the 2 phases are regular. That is partly why you’d have a greater probability of figuring out by wanting on the flower stem or pistil (it might develop larger and extra woody). So simply ensure to take a look so you do not waste any new-forming fruits.
The Fruit
If the soursop tree is hand pollinated, the fruit set price will usually be a lot increased. With a skillful pair of palms, the profitable fertilization price could possibly be round 80-90%.
