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

Some Characters of Rangeland Vegetation In Batman Province of Beşiri District
Amaç: Batman ili Beşiri ilçesine bağlı 14 köyün mera vejetasyonlarının mera durumu, mera sağlığı, botanik kompozisyondaki baklagiller, buğdaygiller, diğer familya bitkileri, azalıcı, çoğalıcı ve istilacı bitki oranları rapor edilmiştir. Materyal ve Metot: Meraların vejetasyon ölçümleri modifiye edilmiş tekerlekli lup (halka) metodu kullanılarak belirlenmiştir. Vejetasyon etüdü meradaki hakim bitkilerin çiçeklendiği dönemde, her durakta 4 hatta toplam 400 noktada; doğu, batı, kuzey ve güney yöneyleri esas alınarak, bitki okumak suretiyle yapılmıştır. Okuma neticesinde tespit edilen bitki türleri azalıcılar, çoğalıcılar ve istilacılar olmak üzere 3 sınıfa ayrılmışlardır. Bulgular: Yapılan vejetasyon etütlerinde 117 farklı tür tespit edilmiştir. Tespit edilen türlerin 17 tanesi (%30.87) buğdaygil, 32 tanesi (%34.65) baklagil ve 68 tanesi (%34.48) diğer familyalara ait türler olduğu belirlenmiştir. Belirlenen türlerin kalite derecelerine göre dağılımına göre bitkilerin 7 adedinin (%2.56) azalıcı, 8 adedinin (%6.83) çoğalıcı ve 102 adedinin (%90.61) istilacı türlerden oluştuğu tespit edilmiştir. Sonuç: Araştırma alanlarının mera durumu yönünden “zayıf mera”, mera sağlığı açısından ise “sağlıklı mera “ sınıfına dahil olmuştur. Ülkemiz koşullarındaki meralarda olduğu gibi, araştırma alanı meraları üzerinde de aşırı, erken ve düzensiz otlatma yapılmaktadır. Meralarımızın bozulmasında en önemli etkenlerden biri de meraların kapasitelerinin çok üzerinde hayvanla otlatılmasıdır. Bu meralarda sürdürülebilirliğin devam etmesi bakımından, en başta otlatma planının doğru bir şekilde yapılması, sonrasında başta gübreleme ve yabancı ot savaşımı olmak üzere bazı bakım ve ıslah işlemlerinin uygulamaya konulması ve ayrıca uygulamaların da sık sık güncellemeleri gerekliliği göz önünde bulundurulmalıdır.Objective: The aim of this study was to determine the status, health, rate of legumes, wheat and other family plants in botanical composition; proportions of decreasing, increasing and invasive plants in pasture vegetations of 14 villages of Batman province Beşiri district. Materials and Methods: The vegetation measurements of the rangelands were determined by modified wheel loop method. Vegetation surveys was conducted by readings at flowering stage of dominant plants in the rangeland, at a total of 400 points, including 4 lines at each stop through to the east, west, north and south directions. Identified plant species were divided into 3 classes as decreasers, increasers and invaders. Results: In the vegetation studies, 117 different species were determined. Of the identified species, 17 were gramineae (30.87%), 32 were leguminous (34.65%) and 68 were from other families (34.48%). It was determined that 7 of the plants (2.56%) were decreasers, 8 of them (6.83%) were replicator and 102 of them (90.61%) were invasive species. Conclusion: As a result, the studied rangelands were classified as “weak” in terms of condition and “healthy” in terms of rangeland health. As same in other rangelands in Turkey, the studied rangelands were found under extreme, early and irregular grazing pressure. This situation is the most important factor in the degradation of Turkish rangelands. In order to maintain sustainability of these rangelands, it is necessary to perform a grazing plan and then to implement some maintenance and rehabilitation processes, particularly fertilization and weed control, and also to update applications frequently
