Phool — Paudhe Ka Reproduction Ang 🌸
Phool sirf sundarta ke liye nahi hai — wo paudhe ka reproduction (prajanan) ang hai! Uske rang, khushboo aur meethe ras (nectar) ka ek hi maqsad hai: keedon ko bulakar pollination (paraagan) karwana.
📌 Phool ke 4 hisse:
🍃 Sepal — kali ki suraksha
🌸 Petal — keedon ko aakarshit karna
♂️ Stamen (anther + filament) — NAR hissa, pollen banata hai
♀️ Carpel/Pistil (stigma + style + ovary) — MAADA hissa
🌼 Ubhaylingi (bisexual) phool: jisme stamen aur carpel dono hon —
jaise gudhal (hibiscus), sarson.
🌽 Eklingi (unisexual) phool: jisme sirf ek hissa ho — jaise papita, tarbooz,
makka.
🐝 Pollination
📌 Pollination: Anther se pollen ka stigma tak pahunchna.
| Prakar | Kya hota hai | Variation (vividhata) |
|---|---|---|
| Self-pollination (swa-paragan) | Usi phool ka (ya usi paudhe ke doosre phool ka) pollen | Kam |
| Cross-pollination (par-paragan) | Doosre paudhe ka pollen | Zyada ✅ |
🚚 Pollen kaise pahunchta hai? Keede (bhaware, titli), hawa, paani, ya pakshi (jaise sunbird). Isiliye phoolon ne rang, khushboo aur nectar "vikasit" kiye — ye keedon ke liye vigyapan (advertisement) hai!
Gehun, makka aur ghaas ke phool rangeen nahi hote aur unme khushboo bhi nahi hoti — kyunki unhe keedon ki zaroorat hi nahi! Unka pollen halka aur sookha hota hai jo hawa mein ud jaata hai, aur unka stigma bada aur pankh jaisa hota hai taaki hawa se pollen pakad sake. Prakriti ne har tareeke ke liye alag design banaya.
💫 Fertilisation
1️⃣ Pollen stigma par chipakta hai (stigma chipchipa hota hai)
2️⃣ Pollen se ek POLLEN TUBE nikalti hai jo style ke andar se
neeche ovary tak badhti hai
3️⃣ Tube ovule tak pahunchti hai aur nar gamete (male gamete) ko
andar pahuncha deti hai
4️⃣ Nar gamete (yugmak) + maada gamete (ande) mil jaate hain →
ZYGOTE banta hai
📌 Fertilisation ke baad kya banta hai:
• Zygote → badhkar embryo (bhroon)
• Ovule → BEEJ (seed)
• Ovary → PHAL (fruit)
• Baaki hisse (petal, stamen, stigma) sookh kar gir jaate hain
Jo aam aap khaate ho, wo kabhi ek phool ki ovary tha! Aur uske andar ki guthli — wo kabhi ek chhota sa ovule tha. Isiliye har phal ke andar beej hote hain: kyunki phal ovary se banta hai aur beej ovule se. Aur agle baar dhyan dena — kai phalon (jaise seb, tamatar) par neeche ek chhota sookha nishaan hota hai. Wo purane phool ke sepal ya style ka nishaan hai!
🌱 Germination (ankuran): Sahi nami, hawa aur taapmaan milne par beej ke andar ka embryo badhna shuru karta hai — jad neeche aur ankur upar. Naya paudha taiyaar!
Bharat mein madhumakkhi paalan (beekeeping) sirf shahad ke liye nahi — makkhiyan kheton mein pollination karti hain jisse paidavaar 20-30% tak badh jaati hai! Isiliye keetnashak (pesticide) ka andha-dhundh istemal khatarnaak hai — wo makkhiyon ko maar deta hai, aur phir pollination hi nahi hoti. Kisan aur madhumakkhi dono ek doosre par nirbhar hain.
