Selektsiya - bu o'simlik xususiyatlarini ataylab yaxshilash va kerakli iste'mol xususiyatlariga erishish jarayonidir. Ko'pgina zamonaviy bog'bonlar bu jarayonda bilmagan holda ishtirok etadilar va ekish uchun eng yaxshi urug'larni tanlaydilar. Biroq, ongli ravishda selektsiya noyob shakllar, ta'mlar va atrof-muhitga chidamlilikni yaratish uchun navlarni ataylab chatishtirish imkonini beradi. Bu mahorat oddiy bog'ni botanika tajribalari uchun maydonga aylantiradi.<\/p>\n

\"O'zingizning<\/p>\n

Naslchilikda sun'iy selektsiya usullari<\/h2>\n

Sun'iy selektsiya eng aniq xususiyatlarga ega bo'lgan ota o'simliklarni tanlashga asoslangan selektsiyaning asosidir. Sabzavotchilikda bu usul ma'lum bir ekinda hosildorlikni, erta pishishni yoki katta meva hajmini oshirish uchun ishlatiladi. Bir necha fasl davomida eng yaxshi namunalarni izchil tanlash navni sizning uchastkangizning mikroiqlimiga moslashtirish imkonini beradi.<\/p>\n

Pomidor yoki loviya kabi o'z-o'zini changlatadigan ekinlar uchun bu usul izchil natijalar beradi, chunki nasl ota-onaning xususiyatlarini deyarli to'liq takrorlaydi. Biroq, o'zaro changlanadigan turlar bilan ishlashda hasharotlar tomonidan ochiq changlanish oldindan aytib bo'lmaydigan o'zgaruvchanlikka olib keladi. Changlatuvchilarni nazorat qilmasdan, yangi avlod xususiyatlarining sofligini kafolatlash mumkin emas.<\/p>\n

Yangi boshlovchilarning asosiy xatosi - turli navlar orasida asalarilar tomonidan tasodifiy changlanishga tayanishdir. Bu xususiyatlarning xilma-xilligiga olib keladi, yuzlab urug'lardan atigi bir nechtasi kutilgan natijalarga erishadi. Izchil natijalarga erishish uchun changni uzatish jarayoniga qo'lda aralashish talab etiladi.<\/p>\n

O'zaro changlanishning o'ziga xos xususiyatlari<\/h2>\n

Qovoq kabi ko'pgina bog' ekinlari o'zaro changlanadi, bu ularni hasharotlarga juda bog'liq qiladi. Asalarilar va arilar changni tasodifiy ravishda uzatadilar, turli xil gullarga va hatto turli o'simlik turlariga tashrif buyuradilar. Natijada, tuxumdon normal rivojlanishi mumkin, ammo urug'lar ichidagi genetik material faqat keyingi yilda paydo bo'ladigan xususiyatlar aralashmasi bo'ladi.<\/p>\n

\"Bog'<\/p>\n

Bunday mevalardan urug'lardan foydalanganda, bog'bonlar oldindan aytib bo'lmaydigan nasllarga duch kelishadi. Buning oldini olish uchun sun'iy changlatishdan oldin va keyin urg'ochi gullarni ajratib olish kerak. Bu tanlangan "otalik" navning changi pistilga yetib borishiga ishonch hosil qilishning yagona yo'li.<\/p>\n

Tajribalar uchun ekin tanlash<\/h2>\n

Gibridizatsiyaning birinchi urinishi uchun qovoq eng yaxshi tanlovdir. Ularning katta, osongina ajralib turadigan erkak va urg'ochi gullari bor, bu esa qo'lda changlatishni osonlashtiradi. Muvaffaqiyatli gibridizatsiya faqat bitta tur ichida mumkinligini yodda tutish muhimdir.<\/p>\n

Qovoq turi<\/td>\nMadaniyatlarga misollar<\/td>\n<\/tr>\n

Qo'lda changlatish bo'yicha bosqichma-bosqich ko'rsatmalar<\/h2>\n
    \n
  1. Kechqurun erkak va urg'ochi o'simliklardagi ochilmagan kurtaklarni folga bilan o'rab yoki ip bilan bog'lab ajratib oling.<\/li>\n
  2. Ertalab, soat 11:00 dan oldin, izolyatsiyani olib tashlang, erkak guldan barglarni olib tashlang, faqat anterlarni qoldiring.<\/li>\n
  3. Anterlardan changni ehtiyotkorlik bilan urg'ochi gulning stigmasiga surting.<\/li>\n
  4. Begona gulchanglarning kirib kelishini oldini olish uchun urg'ochi gulni ip bilan qayta yoping.<\/li>\n
  5. Changlangan gulga sana va ota navining nomini yozing.<\/li>\n
  6. Meva pishganidan so'ng, urug'larni olib tashlang, yaxshilab quriting va qog'oz paketlarga soling.<\/li>\n<\/ol>\n

    Gibrid xususiyatlarni fiksatsiya qilish<\/h2>\n

    Birinchi avlod duragaylari (F1) odatda bir xil bo'ladi, lekin ularning urug'lari har doim ham ota-ona xususiyatlarini to'liq saqlab qolavermaydi. Agar hosil bo'lgan urug' ushbu mezonlarga javob bersa, xususiyatlarni mustahkamlash uchun bitta o'simlik ichida majburiy o'z-o'zini changlatish zarur. Bu genotipni "tozalash" imkonini beradi va keyingi avlodlarda duragayni barqarorroq qiladi.<\/p>\n

    \"Kelgusi<\/p>\n

    Tez-tez so'raladigan savollar<\/h2>\n

    Qovoqni qovoq bilan chatishtirish mumkinmi?<\/h3>\n

    Ha, agar ular bir xil turga mansub bo'lsa, masalan, qattiq po'stloqli qovoq. Aks holda, urug'lar pishmaydi yoki yashovchan bo'lmaydi.<\/p>\n

    Changlatish uchun eng yaxshi vaqt qachon?<\/h3>\n

    Optimal vaqt - erta tong, gulchang eng faol bo'lgan va hasharotlar hali begona genetik materialni o'tkazishga ulgurmagan payt.<\/p>\n

    Gulning changlanishga tayyorligini qanday bilasiz?<\/h3>\n

    Kurtak katta bo'lishi kerak, barglari sarg'aygan uchlari bilan, lekin hali ochilmagan.<\/p>\n

    Tanlashdan oldin o'simliklarni boqish kerakmi?<\/h3>\n

    Ha, yuqori sifatli urug'larni yetishtirish uchun o'simliklar yetarli miqdorda ozuqa bilan ta'minlanishi kerak, aks holda meva changlanishdan keyin tuxumdonini tushirishi mumkin.<\/p>","protected":false},"excerpt":{"rendered":"
