“…Female flowers, of which there are less than male flowers, are borne at the inflorescence's tip, while the male flowers, of which there are many more, are carried lower on the plant. While there is usually a ratio of 29 male flowers to every female flower on an inflorescence, the actual ratio can be anywhere from 25 male flowers to 93 female flowers [14]. Jatropha Curcas L. oil production is expected to reach 1,590 kg/ha [15The fruit is an ovoid capsule shaped like a trilobite and measuring between 23 and 30 millimeters in length and 28 millimeters in breadth.…”

This article provides a bibliography discussing the significance of Jatropha as a biofuel crop around the world. In the family Euphorbiaceae, the genus Jatropha contains about 170 species of shrubs and trees (some of which are deciduous, such as Jatropha Curcas L.). It’s a perennial that can withstand dry conditions, grows well in soil with low fertility, and yields a lot of oil per plot. Plants produce seeds for up to 50 years and grow rapidly. Due to its many advantages, jatropha has attracted attention as a potentially useful tropical plant in the expansion of renewable energy sources. It has more real and intangible environmental advantages than any other competition, and it deserves to be recognized as such. In comparison to other biodiesel feedstocks, jatropha produces more oil for its price, and it has excellent fuel characteristics. It’s a source of energy rather than food because it comes from an oilseed that isn’t edible. If you’re looking for a cleaner alternative to diesel, consider jatropha, which may be utilized in diesel engines without sacrificing performance. Additionally, jatropha has a major impact on the quality of life in rural areas. According to some estimates, the plant might give a weight-based oil production of up to 40% per seed. This article explores the environmental and economic significance of the Jatropha tree, as well as the characteristics of its seeds in relation to oil production and the possibility of using it as an environmentally friendly biofuel, as well as its methods of propagation, requirements for its growth, and what it needs from developmental processes in cultivation.

The scarcity of fuel oil in the future needs to be anticipated by preparing alternative energy. One of the alternative energy sources developed is Jatropha. However, the development of Jatropha should use marginal land as a cultivation area, like a dry land, because the food crops and horticulture use productive land for cultivation. Furthermore, Jatropha development through breeding is an effort to obtain superior varieties as biodiesel producers. This study aimed to determine the best phenotype characteristics of hybrid Jatropha plants as superior candidate trees. This research applied a descriptive qualitative method to determine the characteristics of Jatropha crossing results. The Jatropha characterization was conducted at the experimental garden of Kedung Pengaron Village, Kejayan Sub-district, Pasuruan Regency. The experimental garden was included dry land for Jatropha cultivation. The result showed ten selected genotypes of hybrid Jatropha were found, including 05.01.01, 05.01.02, 05.02.02, 05.02.09, 05.03.17, 05.03.16, 05.04.16, 05.04.15, 06.01.02, 06.01.15. These were based on the two-phase observations, consisting of vegetative and generative observations. The plants’ morphological characters were observed, comprising the stems, leaves, flowers, fruits and seeds. In the vegetative phase, diversity was found in the number of leaves, leaf length and age of flowering, while in the qualitative phase, the shoot colors were more diverse. Moreover, less variations were figured out in the color character of the petiole and the number of shoots. These ten genotypes of hybrid Jatropha are the best genotypes that are resistant to drought with selected agronomic characters.

“…The plants are monoecious with masculine and feminine flowers in the same inflorescence (Chang-wei, Kun, You, & Yongyu, 2007). Normally, inflorescences produce a central female flower surrounded by a group of male flowers, which normally include 1-5 female flowers and 25-93 male flowers (Raju & Bahadur, 2013). Masculine flowers have ten stamens arranged in two tiers of five each.…”

Jatropha curcas is a native Mexican plant, distributed in the forests of coastal regions; it has shown potential for the production of biofuel, and its raw protein can be used as animal feed. Nevertheless, its current varieties have low yield and production variability, as it is in domestication period. The knowledge of the pollen grains is fundamental for studies of Jatropha reproductive biology and breeding for genetic improvement to generate new hybrids and improve fruit and seed yield. This study compared pollen morphology of four Jatropha species, which include two varieties of J. curcas (one toxic from India and one non-toxic from Mexico), and two varieties of wild J. cinerea (Sinaloa and Baja California Sur); additionally, pollen was collected from wild J. platyphylla (Sinaloa) and J. vernicosa (Baja California Sur) to characterize them palynologically. We used a scanning electron microscope to describe the size and shape of pollen grains. Pollen grains were observed spheroidal. The diameter of the varieties of toxic and non-toxic J. curcas and that of J. platyphylla were 58 ± 2.3, 54 ± 1.7, and 51 ± 2.4 µm, respectively; the number of clavae was 84 ± 10, 108 ± 15, and 180 ± 15.5, respectively. Pollen grains of J. cinerea (Sinaloa) had a diameter of 50 ± 1.7 µm and 220 ± 14 clavae by area; J. cinerea (Baja California Sur) had a diameter of 45 ± 1.9 µm and 195 ± 14.7 clavae. Pollen grains of J. vernicosa had a diameter of 46 ± 2.1 µm and 231 ± 25.6 clavae. The ornamentation of the exine showed clava with capita gemma shaped for varieties of J. curcas species and clavum shaped for J. platyphylla, J. cinerea and J. vernicosa species. The studied varieties have a cross-linked endexine and ectexine intectate. Luminal bacules were observed in the reticular space of J. curcas varieties while none were present in the varieties of J. cinerea, J. platyphylla, and J. vernicosa. Rev. Biol. Trop. 65 (2): 799-806.
