is there such a thing as male and female papaya trees? if so, which one will fruit? male or female tre?

Answer 1

the male papaya only makes flowers you have to cut it down as soon as you know ,otherwise they contaminatr the female fruit bearing trees
got lots in the garden
out of a handfull of seeds about half are useless males

Answer 2

Yes, there are male and female papaya trees. That is because according to sexuality, The plant, Carica papaya, has imperfect flowers. On how it is arranged in the plant,, we call it dioecious-- male and female flowers borne on different plants.

note: the opposite is monoecious- male and female flowers borne on the same plant (like corn, Zea mays, for example).

Regarding which one is a fruit, the obvious answer will be the female one. That is because it is the ovary of the flower which becomes ripened into a fruit upon fertilization; and the ovary is part of the carpel, the female part of the flower.

The male flower, on the other hand, is the source of pollen, the microgametangium, that will pollinate the carpel, and will release the 2 sperm cells by means of a pollen tube. When the egg and sperm fuse (a process called syngamy or fertilization), the ovary becomes the fruit, and the ovules, the seeds. So that is why, seeds in flowering plants can always be found inside the fruit; because the ovules are found inside the ovary.

note: Carica papaya has marginal placentation; the many seeds are found along the margins; and has a single locule; as seen when we cut in cross or transverse section.

Hope that helps. :-)

Answer 3

Let us talk about papaya tree.

Though it is difficult to be sure about the gender of the tree yet an identification of male trees is essential as letting a number of male trees grow is a waste.

Do not, however, under estimate the importance of male trees.

While sometimes both male and female flowers grow on the same plant or both sexes may be present in the same flower, but there are those trees that have only female flowers and need a male plant nearby.
Such plants help increase productivity. ( Papaya is one such plant)

However, most people cannot distinguish between male and female trees. (See the accompanying pictures).

Male flowers are borne on long, wire-like twigs, whereas female or hermaphrodite flowers are attached near the mainstem, either singly or in tows or threes.

These are also bigger in size than their male counterparts.

One male tree is generally sufficient for 10 female trees, the rest can be cut.

Answer 4

Only female papaya tree will fruit. Male one has a lot of flowers but never gain fruits.

Answer 5

yes there r different trees n papaya for male and female.
u have to have at least one male tree in ur garden to pollinate the females to bear fruit . it may work otherwise also but better to have one male . others can be cut down and not required. females only will bear fruits.

Answer 6

Depends on the individual. Where I live (Adelaide), I don't see a huge difference between males and females when it comes to mobile usage. A lot of the teens I see at school seem to have their phones in class on Facebook, boy or girl, and text each other from different classrooms (pretty pathetic, in my opinion). I, a female, rarely use my phone, except when I am on school trips, in which case I keep my phone in my pocket, and when on the train or bus I sit on my lap in case my mother texts or calls.

Answer 7

Dioecous plants have seperate plant bodies, female plants bear fruits and male plants become only the source for pollen grains.
