Baklagillerde generatif organ
(çiçek ve bakla) dökümü önemli bir problemdir. Bitki tarafından çok sayıda
çiçek üretilse de bu çiçeklerin çoğu dökülmekte ve baklaya dönmemektedir.
Aslında, aşırı sayıda bakla sayısı, kaliteyle ters orantılı olduğundan, orta
derecede çiçek dökümü tarımsal açıdan istenen bir özelliktir. Fakat genellikle
baklagiller normalden fazla sayıda generatif organı yüksek sıcaklık, yetersiz
ışık, kuraklık, besin elementi yetersizliği, yüksek bitki yoğunluğu sonucunda
dökmektedir. Bu çalışmada, öne çıkan iki hipotez olan besin eksikliği ve hormonal
kontrol hipotezleri ışığında, baklagillerde generatif döküm sorunu
incelenmiştir. Ayrıca, bu konuda yürütülmüş çalışmalardaki bazı eksikliklere ve
bunların ortaya çıkardığı fırsatlara değinilmiştir.

Reproductive Abortion Problem in Legumes

Öz

Generative organ (flower and pods) abortion is an important problem in
legumes. Although many flowers are produced by the plant, most of these flowers
are shed and do not produce pods. In fact, modest flower abortion is an
agriculturally desirable feature since an excessive number of pods is inversely
proportional to quality. But generally, legumes shed excessive number of
generative organs as a result of high temperature, insufficient light, drought,
nutrient deficiency and high plant density. In this article, generative
abortion was investigated in the light of two current hypothesis -nutritional
deficiency and hormonal control hypothesis. In addition, some deficiencies in
the literatures on this subject and the opportunities they create are
mentioned.
