Flowering in apple

Gibberellins (GAs) can have profound effects on growth and development in higher plants. In contrast to their flowering-promotive role in many well-studied plants, GAs can repress flowering in woody perennial plants such as apple (Malus x domestica Borkh.).

Flower bud formation is a intricate phenomenon. Numerous studies on flower bud formation of temperate fruit plants have been conducted in many .In spite of that, a great part of the most important characteristics of flower bud formation remains insufficiently clarified both by theoretical biology and applied horticulture. Special attention deserves the clarification of the morphogenetic changes that occur between the vegetative state of the buds and the initiation of flower organs.

An investigation was carried out at cashew research station under AICRP on cashew Ranasinghapur, Bhubaneswar, Khurda, during the year 2015-2017, to study the variability in thirty land races of cashew. It was found that, the heritability was highest in canopy area per m2 (99.82%) and minimum was recorded in canopy spread north-south (61.54%). The genetic variability with heritability gives a reliable picture of the genetic advance to be expected for the selection.

Generally, double-flowered varieties are more attractive than single-flowered varieties in ornamental plants. Japanese gentian is one of the most popular floricultural plants in Japan, and it is desirable to breed elite double-flowered cultivars. In this study, we attempted to characterize a doubled-flower mutant of Japanese gentian.

Floral induction is an important stage in the apple tree life cycle. In ‘Nagafu No. 2’, which was derived from a ‘Fuji’ bud sport, flower bud formation is associated with serious problems, such as fewer and inferior flower buds, a long juvenile phase, and an alternate bearing phenotype.

Although the most common path of infection for fire blight, a severe bacterial disease on apple, is via host plant flowers, quantitative trait loci (QTLs) for fire blight resistance to date have exclusively been mapped following shoot inoculation. It is not known whether the same mechanism underlies flower and shoot resistance.

The flowering behavior of wax apple in new alluvial zone of West Bengal with five germplasm was carried out at Horticulture Research Station, Mondouri, Bidhan Chandra Krishi Viswavidyalaya in the year 2015-16 with an objective to provide a wealth of usable information to improve wax apple breeding programme. A wide range of variation was noted in respect of different parameters of flowering behavior. Flower bud emerged from 3 rd week of October to last week of April with a period of bud development of 15.25 to 31.75 days among different germplasm of wax apple.

The present investigation aimed at evaluating the importance of ca based nutrient sprays viz., the Bio-efficacy of Megacal containing Ca, Mg, K, Zn, Iron and Cu, as organic product. The sprays were used on apple cv. Red Delicious for a period of two years at farmers’ field in district Shopian during 2016 and 2017. Healthy trees of uniform age (20 years) were selected. Cultural practices and plant protection measures were uniform for all the selected trees, irrespective of treatments. On each tree four branches from four sides were marked, for different flower and fruit observation measures.

The study was carried out in the experimental orchard of the HRTS & KVK, Kandaghat, Dr Yashwant Singh Parmar University of Horticulture and Forestry, Nauni, Solan (H.P.) during the year 2015-16. The experiment was laid out in Randomized Block Design with four replications. The observations were recorded on various parameters of tree growth, flowering, fruit set and yield. Among different cultivars Oregon Spur II recorded maximum increment in the trunk girth (8.10 %) and tree height (22.37 %). Tree spread (1.74 m) and tree volume (2.

Apple blossom thrips (Thysanoptera: Thripidae) is serious pest of apple bloom in some areas of Bandipora and Anantnag of kashmir valley. A field trials were laid out at Dangerpora Kullar, Luckbown (District Anantnag) and Arin and bagh (District Bandipora) in a completely Randomized Block Design during 2015 - 2017. Apple trees of variety “Red Delicious”, 13-16 years of age were selected for the field trial. The highest pest incidence (5-8) thrips per flower was recorded in Madar bandipora. The spraying of the treatments, viz., Thiochloroprid @ 0.3, 0.4 and 0.

Apple flavor is characterized by combinations of ester compounds, which increase markedly during fruit ripening. The final step in ester biosynthesis is catalyzed by alcohol acyl transferases (AATs) that use coenzyme A (CoA) donors together with alcohol acceptors as substrates. The gene MpAAT1, which produces a predicted protein containing features of other plant acyl transferases, was isolated fromMalus pumila(cv. Royal Gala). TheMpAAT1gene is expressed in leaves, flowers and fruit of apple.
