Baklagillerde Generatif Döküm Sorunu

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

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.
